DIAGNOSING AN ELECTRICAL FAILUREPerforming Efficient Electrical Circuit Diagnosis and Troubleshooting
STEP DESCRIPTION
Step 1 Obtain detailed information about the conditions and the environment when the electricalincident occurred.
Step 2Operate the affected system, road test the vehicle if necessary.Verify the parameter of the incident.If the problem cannot be duplicated, refer to “Electrical Failure Simulation Tests”.
Step 3
Gather the proper diagnosis material together including:• Electrical Power Supply Routing Diagram• System Operation Descriptions• Applicable Service Manual Sections• Check for any Service Bulletins• Identify where to begin diagnosis based upon your knowledge of the system operation
and the customer comments.
Step 4Inspect the system for mechanical binding, loose connectors or wiring damage.Determine which circuits and components are involved and diagnose using the ElectricalPower Supply Routing Diagram and Harness Layouts.
Step 5 Repair the circuit or replace the component as necessary.
Step 6Operate the system in all modes. Verify the system functions properly under all conditions.Confirm you have not inadvertently created an additional new incident during yourdiagnosis or repair steps.
Electrical Circuit Failure Simulation TestsOften the symptom is not present when the vehicle is brought in for service. If possible, re-create the conditionspresent at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The following illustratestests to simulate the conditions/environment under which the owner experiences an electrical incident.
The tests are broken into the seven following topics:• Vehicle Vibration Test• Heat Sensitive Test• Freezing Test• Water Intrusion Test• Electrical Load Test• Cold or Hot Start Up Test• Voltage Drop Test
NOTE :Always get a thorough description of the incident from the customer. It is important for simulating the conditions ofthe problem.
01–16 Chery Automobile Co., Ltd.
DIAGNOSING AN ELECTRICAL FAILURE
01
Vehicle Vibration TestThe problem may occur or become worse while driving on a rough road or when the engine is vibrating (idle with A/Con). In such a case, check for a vibration related condition. Refer to the following vehicle areas:
Connectors & Harness
• Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gentlyshake each connector and harness while monitoring the system for the incident you are trying to duplicate. Thistest may indicate a loose or poor electrical connection.
NOTE :Connectors can be exposed to moisture. It is possible for a thin film of corrosion to form on the connector terminals.A visual inspection may not reveal this without disconnecting the connector. If the problem occurs intermittently, per-haps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the terminals on relatedconnectors in the system.
Sensors & Relays
• Gently apply a slight vibration to sensors and relays in the system you are inspecting. This test may indicate aloose or poorly mounted sensor or relay.
Engine Compartment
• There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the thingsto check for are:
− Connectors not fully seated.− Wiring harness not long enough and is being stressed due to engine vibrations or rocking.− Wires laying across brackets or moving components.− Loose, dirty or corroded ground wires.− Wires routed too close to hot components.
• To inspect components under the hood, start by verifying the integrity of the ground connections (See GroundInspection described later). First, verify that the system is properly grounded. Then check for any loose connec-tions by gently shaking the wiring or components as previously explained. Using the wiring diagrams, inspectthe wiring for continuity.
Behind The Instrument Panel
• An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehiclevibration can aggravate a harness which is routed along a bracket or near a mounting screw.
• An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)during vehicle vibration. If the wiring runs under seating areas, inspect wire routing for possible damage orpinching.
Heat Sensitivity TestThe customer’s concern may occur during hot weather or after the vehicle has sat for a short time. In such cases youwill want to check for a heat sensitive condition.
To determine if an electrical component is heat sensitive, heat the component with a heat gun or equivalent.
CAUTION:Do not heat components above 60 °C (140 °F).
If the incident occurs while heat testing the component, replace or properly insulate the component as needed.
Freezing TestThe customer may indicate the incident goes away after the vehicle warms up (winter time). The cause could berelated to water freezing somewhere in the wiring/electrical system. There are two methods to check for this:• The first method is to arrange for the owner to leave the vehicle overnight. Make sure it will get cold enough to
demonstrate the complaint. Leave the vehicle parked outside overnight. In the morning, do a quick and thor-ough diagnosis of those electrical components which could be affected.
• The second method is to put the suspect component into a freezer long enough for any water to freeze. Rein-stall the part into the vehicle and check for the reoccurrence of the incident. If it occurs, repair or replace thecomponent as needed.
01–17Chery Automobile Co., Ltd.
DIAGNOSING AN ELECTRICAL FAILURE
Water Intrusion TestThe incident may occur only during high humidity or in rainy/snowy weather. In such cases the incident could becaused by water intrusion on an electrical part. This can be simulated by soaking the car or running it through a carwash.
Electrical Load TestThe incident may be electrical load sensitive. Perform diagnosis with all accessories (including A/C, rear windowdefogger, radio, fog lamps) turned on.
Cold or Hot Starting TestOn some occasions an electrical incident may occur only when the vehicle is started cold, or it may occur when thevehicle is restarted hot shortly after being turned off. In these cases you may have to keep the vehicle overnight tomake a proper diagnosis.
Voltage Drop TestVoltage drop tests are often used to find components or circuits which have excessive resistance. A voltage drop ina circuit is caused by a resistance in the circuit during operation.• Check the circuit using a Digital Multimeter (DMM).• When measuring resistance with a DMM, remember that contact by a single strand of wire will give a reading
of 0 ohms. This would indicate a good circuit. When the circuit operates, this single strand of wire is not ableto carry the current. The single strand will have a high resistance to the current. This will be indicated as aslight voltage drop.
• Unwanted resistance can be caused by the following:− Undersized wiring (single strand example)− Corrosion on switch contacts− Loose wire connections or splices.
Precautions For Handling Control Modules and Electrical Components• Never reverse polarity of battery terminals.• Only install components specified for the vehicle.• Before replacing the control module, check the input and output and functions of the components.• When disconnecting components:
− Do not apply excessive force when disconnecting a connector.− If a connector is installed by tightening bolts, loosen mounting bolt, then remove it by hand.
• When connecting components:− Before installing a connector, make sure the terminal is not bent or damaged, and then correctly connect it.− When installing a connector by tightening bolts, tighten the mounting bolt until the painted area of the con-
nector becomes even with the surface.• Do not apply excessive shock to the control module by dropping or hitting it.• Be careful to prevent condensation in the control module due to rapid temperature changes and do not let
water or rain get on it. If water is found in the control unit, dry it fully and then install it in the vehicle.• Be careful not to let oil get on the control module connector.• Avoid cleaning the control module with volatile oil.

DIAGNOSING AN ELECTRICAL FAILURE
01
• When using a DMM, be careful not to let the test probes touch each other causing a short circuit. Prevent thepower transistor in the control module from beingshorted to damaging battery voltage.
• When checking input and output signals of the con-trol module, use the specified test adapter (if appli-cable).
How To Check Electrical ConnectorsMany electrical problems are caused by faulty electricalconnections or wiring. It is also possible for a stickingcomponent or relay to cause a problem. Before con-demning a component or wiring assembly, alwayscheck the electrical connectors for good continuity.
How To Probe Connectors• Connector damage and an intermittent connection
can result from improperly probing the connectorduring circuit checks.
• The probe of a DMM may not correctly fit the con-nector cavity. To correctly probe the connector, fol-low the procedures below using a “T” pin. For thebest contact grasp the “T” pin using an alligatorclip.
Probing From Harness Side• If the connector has a rear cover connector,
remove the rear cover before probing the terminal.• Do not probe waterproof connectors from the har-
ness side. Damage to the seal between the wireand connector may result.
Probing From Terminal Side• Female Terminal:
− Do not insert any object into the female connector, that is bigger than the male terminal.• Male Terminal:
− Carefully probe the contact surface of each terminal using a “T” pin. Do not bend terminal.
How To Check Proper Contact Spring Tension Of Terminal• An enlarged contact spring of a terminal may create intermittent signals in the circuit.• If an intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged contact
spring of female terminal.− Use a male terminal which matches the female terminal.− Disconnect the suspected faulty connector and hold it terminal side up.− While holding the wire of the male terminal, attempt to insert the male terminal into the female terminal.− While moving the connector, check whether the male terminal can be easily inserted or not.
NOTE :If the male terminal can be easily inserted into the female terminal, replace the female terminal.

GENERAL INFORMATIONDescriptionThe 1.6L & 1.8L in-line four cylinder engines have the following features:• Dual overhead camshafts• Four valves per cylinder• Aluminum cylinder head• Aluminum cylinder block (1.6L Engine)• Cast iron cylinder block (1.8L Engine)
OperationThe 1.6L & 1.8L engines utilize 4 valve-per-cylinders and a dual overhead camshaft design. The engines use anindividual coil ignition system. The 1.6L engine uses an aluminum cylinder block, and the 1.8L engine is made of castiron The bearing caps are integrated into the lower cylinder block assembly. An aluminum oil pan bolts to the bottomof the lower cylinder block. The camshafts are mounted in the cylinder head and act against valve tappets to openand close the valves. The camshafts are driven off the front of the cylinder head by one timing belt. The belt is drivenby a sprocket that is located on the crankshaft. The piston assembly is an aluminum piston with a cast iron con-necting rod.
The aluminum cylinder head contains dual overhead camshafts with 4 valve-per-cylinder construction. The valves arearranged in two in-line banks. The cylinder head incorporates powdered metal valve guides and seats. The cylinderhead is sealed to the block using a multi-layer steel head gasket and retaining bolts.

Lubrication SystemThe engine lubrication system operates as follows:• Oil is drawn into the oil pump through the oil pump strainer tube in the sump of the oil pan.• Oil is pumped through the oil filter on the cylinder block.• Oil enters the main oil gallery where it is distributed to the crankshaft main journals and to the cylinder head.• From the main journals, the oil is routed through cross-drilled passages in the crankshaft to lubricate the con-
necting rod bearings. Controlled leakage through the crankshaft main bearings and connecting rod bearings isslung radially outward to cool and lubricate the cylinder walls as well as the entire connecting rod, piston andpiston ring assembly.
• The engine lubrication system is a full-flow filtration, pressure feed type. The oil pump body is mounted to theengine block. The pump inner rotor is driven by the crankshaft.

DIAGNOSIS & TESTING
02–14 Chery Automobile Co., Ltd.
Cylinder Compression Pressure Test• The result of a cylinder compression pressure test can be utilized to diagnose several engine malfunctions.• Ensure the battery is completely charged and the engine starter motor is in good operating condition. Otherwise
the indicated compression pressures may not be valid for diagnostic purposes.− Check engine oil level and add oil if necessary.− Disconnect the spark plug wires.− Remove all spark plugs from engine (as spark plugs are being removed, check electrodes for abnormal
firing indicators fouled, hot, oily, etc.).− Record cylinder number of each spark plug for future reference.− Disconnect fuel injector electrical connectors.− Be sure throttle blade is fully open during the compression check.− Insert compression pressure adaptor or the equivalent into each spark plug hole in cylinder head.− Crank engine until maximum pressure is reached on gauge. Record each cylinder pressure.− Compression should not be less than 1000 kPa and not vary more than 25 percent from cylinder to cylinder.− If one or more cylinders have abnormally low compression pressures, repeat the compression test.− If the same cylinder or cylinders repeat an abnormally low reading on the second compression test, it could
indicate the existence of a problem in the cylinder in question.
NOTE :The recommended compression pressures are to be used only as a guide to diagnosing engine problems. An engineshould not be disassembled to determine the cause of low compression unless some malfunction is present.
Cylinder Head Gasket Test• A cylinder head gasket leak can be located between adjacent cylinders, between a cylinder and the adjacent
water jacket or from an oil passage to the exterior of the engine.• Possible indications of the cylinder head gasket leaking between adjacent cylinders are:
− Loss of engine power− Engine misfiring− Poor fuel economy
• Possible indications of the cylinder head gasket leaking between a cylinder and an adjacent water jacket are:− Engine overheating− Loss of coolant− Excessive steam (white smoke) emitting from exhaust− Coolant foaming

GENERAL INFORMATIONDescriptionThe Engine Control Module (ECM) controls the engine management system. The ECM can adjust for varying drivingconditions and modify fuel and ignition requirements as needed to maintain optimum performance and economy.
The following are the input and output components monitored by the ECM.
ECM Inputs
• Brake Switch Sensor• A/C Pressure Sensor• Camshaft Position (CMP) Sensor• Crankshaft Position (CKP) Sensor• Engine Coolant Temperature (ECT) Sensor• Manifold Absolute Pressure (MAP) Sensor (1.6L)• Air Flow Sensor (1.8L)• Electric Throttle Control Actuator• Power Steering Switch• Accelerator Pedal Position (APP) Sensor• Knock Sensor• Upstream Oxygen Sensor• Downstream Oxygen Sensor• Clutch Pedal Switch• Immobilizer• CAN Bus
ECM Outputs
• Canister Control Valve• Fuel Injectors• Fuel Pump Relay• Electronic Throttle Control Actuator• Ignition Coil• A/C Compressor• Cooling Fan• Oxygen Sensor Heater (Upstream & Downstream)• CAN Bus
OperationThe ECM is a pre-programmed, microprocessor-based digital computer. It regulates ignition timing, air-fuel ratio,emission control devices, charging system, certain transmission features, speed control, air conditioning compressorclutch engagement and idle speed. The ECM can adapt its programming to meet changing operating conditions.
The ECM monitors components and circuits and tests them in various ways depending on the hardware, function,and type of signal. For example, analog inputs such as throttle position or engine coolant temperature are typicallychecked for opens, shorts and out-of-range values. This type of monitoring is carried out continuously. Some digitalinputs like vehicle speed or crankshaft position rely on rationality checks - checking to see if the input value makessense at the current engine operating conditions. These types of tests may require monitoring several componentsand can only be carried out under appropriate test conditions.

DIAGNOSIS & TESTINGDiagnostic Help1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronic
modules through the data network.2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.3. If the Diagnostic Trouble Code (DTC) cannot be deleted, it is a current fault.4. Use only a digital multimeter to perform voltage readings on electronic systems.5. Refer to any Technical Bulletins that may apply to the failure.6. Visually inspect the related wiring harness.7. Inspect and clean all Engine Control Module (ECM) grounds that are related to the most current DTC.8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage
supply circuits that may apply to the DTC.
Intermittent DTC TroubleshootingIf the failure is intermittent perform the following:• Check for loose connectors.• Look for any chafed, pierced, pinched, or partially broken wires.• Monitor the scan tool data relative to this circuit.• Wiggle the related wiring harness and connectors while looking for an interrupted signal on the affected circuit.• If possible, try to duplicate the conditions under which the DTC set.• Look for the data to change or for the DTC to reset during the wiggle test.• Look for broken, bent, pushed out or corroded terminals.• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age, or foreign material.• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.• Remove the Engine Control Module (ECM) from the troubled vehicle and install in a new vehicle and test. If
the DTC cannot be deleted, the ECM is malfunctioning. If the DTC can be deleted, return the ECM to the origi-nal vehicle.
Ground InspectionGround connections are very important to the proper operation of electrical and electronic circuits. Ground connec-tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwantedresistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasticallyaffect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following wheninspecting a ground connection:
1. Remove the ground bolt or screw.2. Inspect all mating surface for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for �add-on� accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires
are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, makesure no excess wire insulation has been crimped creating a bad ground.
Electronic Throttle Control Actuator Self-Learning Operation Introduction
Electronic Pedal Control (EPC) Lamp Control StrategyThe EPC lamp will light when the ignition switch is turned to the ON position and the engine is not running. After theengine is started, the EPC lamp will go off if there is no EPC DTCs that exist in the ECM. If the internal EPC self-check failed, the EPC lamp will continue to light.
Electronic Throttle Control Actuator Self-Learning Condition• Engine stopped and the ignition switch on.• Vehicle speed is 0 km/h.

• The Engine Coolant Temperature (ECT) is between 5.25 °C and 100.5 °C.• The intake air temperature is more than 5.25 °C.• The accelerator pedal fully released.• Battery voltage is more than 12 V.
Electronic Throttle Control Actuator Self-Learning Operating ProcedureTurn ignition switch on for 10 seconds, then turn the ignition switch off. During the procedure, don’t operate any othercomponents.
Self-Learning ComponentsSelf-Learning should be performed on these components under the following conditions:• After replacing the ECM.• After disconnecting and reconnecting the ECM.• After replacing the Accelerator Pedal or Electronic Throttle Control Actuator.
Self-Learning Operating ProcedureTurn the ignition switch on for 10 seconds, then turn the ignition switch off. During the procedure, don’t operate anyother components.
Self-Learning ConditionThe self-learning condition is known as the �Electronic Throttle Control Actuator Self-Learning Condition�.
CAUTION:Make sure that the Electronic Throttle Control Actuator self-learning procedure lasts for at least 10seconds according to the Electronic Throttle Control Actuator self-learning condition. If the self-learning procedure fails, the engine cannot be started, or the EPC lamp will be lit. If this conditionoccurs, the self-learning procedure should be performed again after the DTCs have been erased inECM.

Engine Coolant Temperature Sensor
DescriptionThe Engine Coolant Temperature (ECT) sensor threads into the coolant outlet connector. The ECT is a negativethermal coefficient sensor.
OperationThe ECT provides an input to the Engine Control Module (ECM). As temperature increases, resistance of the sensordecreases. As coolant temperature varies, the ECT sensor resistance changes resulting in a different voltage valueat the ECT sensor signal circuit. The ECM uses the input to control air-fuel mixture, timing, and radiator fan on/offtimes.
Removal & Installation1. Disconnect and isolate the negative battery cable.2. Release the coolant system pressure.
WARNING!
Never remove the pressure relief cap under any conditions while the engine is operating or hot. Failure to followthese instructions could result in personal injury or damage to the cooling system or engine. To avoid havingscalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pressurerelief cap. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn itslowly one turn (counterclockwise). Step back while the pressure is released from the cooling system. When youare certain all the pressure has been released, (with a cloth) turn and remove the pressure relief cap. Failure tofollow these instructions may result in serious personal injury.
3. Disconnect the coolant temperature sensor electri-cal connector.
CAUTION:Remove the coolant temperature sensor whenthe engine is cold.4. Remove the engine coolant temperature sensor

Installation Notes:
• After installing the coolant temperature sensor, check and adjust the coolant level.
Knock Sensor
DescriptionThe knock sensor is attached to the cylinder block. The knock sensor is designed to detect engine vibration that iscaused by detonation.
OperationKnock sensors contain a piezoelectric material which constantly vibrates and sends an input voltage (signal) to theECM while the engine operates. As the intensity of the crystal’s vibration increases, the knock sensor output voltagealso increases.
When the knock sensor detects a knock in one of the cylinders, it sends an input signal to the Engine Control Module(ECM). In response, the ECM retards ignition timing for all cylinders by a specified amount.
The ECM ignores knock sensor input during engine idle conditions. Once the engine speed exceeds a specifiedvalue, knock retard is allowed.
Removal & Installation1. Disconnect and isolate the negative battery cable.2. Disconnect the knock sensor electrical connector.3. Remove the knock sensor retaining bolt (1) and
remove the knock sensor.(Tighten: Knock sensor retaining bolt to 20 N·m)
4. Installation is in the reverse order of removal.
Oxygen Sensor
DescriptionThis oxygen sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1 volt in richerconditions to 0 volt in leaner conditions. This vehicle is equipped with two oxygen sensors (upstream oxygen sensor& downstream oxygen sensor). The oxygen sensors are located before and after the three way catalyst.
OperationThe oxygen sensor has a much longer switching time between rich and lean than the air flow sensor. The oxygenstorage capacity of the three way catalyst (manifold) causes the longer switching time. The oxygen senses the oxy-gen content in the exhaust flow and outputs a voltage between 0 and 1.0 volt. Lean of stoichiometric, air/fuel ratio ofapproximately 14.7:1, the oxygen sensor generates a voltage between 0 and 0.45 volt. Rich of stoichiometric, theoxygen sensor generates a voltage between 0.45 and 1.0 volt.

Crankshaft Position Sensor
DescriptionThe Crankshaft Position (CKP) sensor is located on the flywheel shell facing the gear teeth of the signal plate. Itdetects the fluctuation of the engine revolution. The sensor consists of a permanent magnet and Induction coil.
OperationWhen the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. Thechanging gap causes the magnetic field near the sensor to change. Due to the changing magnetic field, the voltagefrom the sensor changes. The Engine Control Module (ECM) receives the voltage signal and detects the fluctuationof the engine revolution.
Removal & Installation1. Disconnect and isolate the negative battery cable.2. Disconnect the CKP sensor electrical connector.3. Remove the CKP sensor retaining bolt (1) and

Camshaft Position Sensor
DescriptionThe Camshaft Position (CMP) sensor senses the protrusion of the intake valve cam sprocket to identify a particularcylinder. The CMP sensor senses the piston position. When the Crankshaft Position (CKP) sensor becomes inoper-ative, the CMP sensor provides various controls of engine parts instead, utilizing timing of cylinder identification sig-nals. The sensor consists of a permanent magnet and Hall IC.
OperationWhen the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. Thechanging gap causes the magnetic field near the sensor to change. Due to the changing magnetic field, the voltagefrom the sensor changes. The Engine Control Module (ECM) detects the voltage signal and identify piston positionand cylinder timing.

Air Flow Sensor - 1.8L
DescriptionThe air flow sensor is placed in the stream of intake air. The air flow sensor measures the intake flow rate by mea-suring a part of the entire intake flow. The air flow sensor converts the amount of air drawn into the engine into avoltage signal. The Engine Control Module (ECM) needs to know intake air volume to calculate engine load. This isnecessary to determine how much fuel to supply to the engine.
OperationThe air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wireis reduced as the intake air flows around it. The more air,the greater the heat loss. Therefore, the electric currentsupplied to the hot wire is changed to maintain the temperature of the hot wire as air flow increases. The ECMdetects the air flow by means of this current change.
Removal & Installation1. Disconnect the negative battery cable.2. Disconnect the air flow sensor electrical connector.3. For 1.8L engine, remove the air flow sensor retain-
ing bolts (1).(Tighten: Air flow sensor retaining bolts to 5 N·m)
4. Pull sensor up and remove it.5. Installation is in the reverse order of removal.
Accelerator Pedal Position Sensor
DescriptionThe Accelerator Pedal Position (APP) sensor is located inside the accelerator pedal. The accelerator pedal positionsensor can not be serviced by itself. The accelerator pedal must be replaced as a unit.
OperationThe accelerator pedal position (APP) sensor works according to the Hall principal. the sensor is integrated into thepedal lever axis. It consists of a shaft with a ring magnet. This rotates in a printed circuit board with a stator in thefixed Hall elements. This produces a change in the voltage. The accelerator pedal position sensor is supplied with 5volts from the Engine Control Module (ECM). The information regarding accelerator position is supplied to the ECMby means of two voltages.
Removal & Installation1. Disconnect the negative battery cable.2. Remove the instrument panel lower trim panel (See Instrument Panel Removal & Installation in Section 15 Body

Electronic Throttle Control Actuator
DescriptionThe throttle body is located on the intake manifold. It controls air into the intake manifold.
The electronic throttle control actuator consists of the throttle control motor, throttle position sensor, etc. The throttlecontrol motor is operated by the ECM and it opens and closes the throttle valve. The throttle position sensor detectsthe throttle valve position.
OperationFiltered air from the air cleaner enters the intake manifold through the throttle body. A throttle valve (plate) is used tosupply air for idle and driving conditions. The throttle position sensor is part the throttle body. The throttle positionsensor signal is used by the ECM to determine throttle position. The ECM controls the electronic throttle control tometer air into the engine. This regulates engine power. The vehicle is in sense a “Drive by Wire” system.

GENERAL INFORMATIONDescriptionThe evaporation control system prevents the emission of fuel tank vapors into the atmosphere. When fuel evaporatesin the fuel tank, the vapors pass through vent hoses or tubes to an activated carbon filled evaporative canister. Thecanister temporarily holds the vapors. The Engine Control Module (ECM) allows intake manifold vacuum to drawvapors into the combustion chambers during certain operating conditions.
Operation
The ECM will only energize the solenoid when the engine is at operating temperature, but will de-energize it duringperiods of deceleration. When de-energized, no vapors are purged. The pulse-width modulated canister control valvemodulates the fuel vapor purge rate from the vapor canister and fuel tank to the engine intake manifold.

The battery system for this vehicle contains the following components:• Battery - The battery provides a reliable means of storing a renewable source of electrical energy within the
vehicle.• Battery Cables - The battery cables connect the positive and negative charged battery terminal posts to the
vehicle electrical system.• Battery Hold Down - The battery hold down hardware secures the battery in the battery tray.• Battery Tray - The battery tray provides a secure mounting location in the vehicle for the battery and an anchor
point for the battery hold down hardware.
OperationThe battery is designed to store electrical energy in a chemical form. When an electrical load is applied to the ter-minals of the battery, an electrochemical reaction occurs. This reaction causes the battery to discharge electricalcurrent from its terminals. As the battery discharges, a gradual chemical change takes place within each cell. Thesulfuric acid in the electrolyte combines with the plate materials, causing both plates to slowly change to lead sulfate.At the same time, oxygen from the positive plate material combines with hydrogen from the sulfuric acid, causing theelectrolyte to become mainly water. The chemical changes within the battery are caused by the movement of excessor free electrons between the positive and negative plate groups. This movement of electrons produces a flow ofelectrical current through the load device attached to the battery terminals.

GENERAL INFORMATIONDescriptionThe cooling system regulates engine operating temperature. It allows the engine to reach normal operating temper-ature as quickly as possible, maintains normal operating temperature and prevents overheating.
The cooling system also provides a means of heating the passenger compartment. The cooling system is pressurizedand uses a centrifugal water pump to circulate coolant throughout the system.
The cooling system consists of the following components:• Radiator• Coolant• Coolant pump• Electric cooling fans• Electric cooling fans control module• Thermostat• Coolant reservoir• Hoses and clamps• Coolant temperature sensor• Coolant level sensor• Heater core
OperationThe primary purpose of a cooling system is to maintain engine temperature in a range that will provide satisfactoryengine performance and emission levels under all expected driving conditions. It also provides hot coolant for heaterperformance. It does this by transferring heat from engine metal to coolant, moving this heated coolant to the radi-ator, and then transferring this heat to the ambient air.

DIAGNOSIS AND TESTINGCooling System Pressure TestWARNING!
Always allow the engine to cool before opening the cooling system. Do not unscrew the coolant pressure reliefcap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam andhot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions mayresult in serious personal injury.
CAUTION:Do not pressurize the cooling system beyond the maximum pressure listed in the specificationstable in this section, or cooling system components can be damaged.1. Turn the engine off.2. Check the engine coolant level. Adjust the coolant level as necessary.3. Attach the pressure tester to the coolant recovery reservoir. Install a pressure test pump to the quick-connect
fitting of the test adapter.4. Pressurize the engine cooling system. Observe the gauge reading for approximately 2 minutes. Pressure should
not drop during this time. If the pressure drops within this time, inspect for leaks and repair as necessary.5. If no leaks are found and the pressure drops, the pressure relief cap may be leaking. Install a new pressure
relief cap and retest the system.6. If no leaks are found after a new pressure relief cap is installed, and the pressure drops, the leak may be inter-
nal to the radiator transmission cooler (if equipped). Inspect the coolant for transmission fluid and the transmis-sion fluid for coolant. Repair as necessary.
7. If there is no contamination of the coolant or transmission fluid, the leak may be internal to the engine. Inspectthe coolant for engine oil and the engine oil for coolant.
8. Release the system pressure by loosening the pressure relief cap. Check the coolant level and adjust as nec-essary.
Cooling System Concentration Test
CAUTION:Do not mix types of coolant, corrosion protection will be severely reduced.
Coolant concentration should be checked when any additional coolant is added to the cooling system or after a cool-ant drain, flush and refill. The coolant mixture offers optimum engine cooling and protection against corrosion whenmixed to a freeze point of -37 °C to -46 °C. The use of a hydrometer or a refractometer can be used to test coolantconcentration.

GENERAL INFORMATIONDescription
The exhaust system contains the following components:• Catalytic converter assembly• Muffler assembly• Exhaust brackets with isolators• Heated oxygen sensors mounted to the exhaust pipes• Tailpipe assembly
The exhaust system provides an exit for exhaust gases and reduces engine noise by moving exhaust gases throughthe catalytic converter, a muffler inlet pipe and a muffler. Rubber exhaust hanger insulators attach the exhaust systemto the mounting hooks.
WARNING!
Exhaust gases contain carbon monoxide which can be harmful to your health and are potentially lethal. Exhaustsystem leaks should be repaired immediately. Never operate the engine in enclosed areas. Failure to followthese instructions may result in personal injury or death.
OperationIn order to reduce vehicle emissions released by the engine, the catalytic converter is required to perform in all oper-ating conditions. This reduction is especially beneficial during the cold start and warm up phases of operation. It isduring these phases when a majority of the tailpipe emissions occur on today’s cars because the catalytic converterhas not yet reached its operating temperature. The exhaust system channels exhaust gases from the engine andaway from the vehicle.

Catalytic Converter
DescriptionThe catalytic converter is attached to the exhaust manifold using fasteners and a gasket for sealing.
The catalytic converter plays a major role in the emission control system by operating as a gas reactor. Its catalyticfunction is to speed the heat-producing chemical reaction of components in the exhaust gases in order to reduce airpollutants.
OperationCatalyst operation is dependent on its ability to store and release the oxygen needed to complete the emissions-reducing chemical reactions. As a catalyst deteriorates, its ability to store oxygen is reduced. Since the catalyst’sability to store oxygen is somewhat related to proper operation, oxygen storage can be used as an indicator of cat-alyst performance.
CAUTION:Unleaded gasoline must be used in order to avoid damaging the catalyst core.
CAUTION:Do not allow the engine to operate above 1200 RPM in Neutral for more than 5 minutes. This mayresult in excessive exhaust system/floor pan temperatures because of the lack of air movementunder the vehicle.

GENERAL INFORMATIONDescriptionThe QR519MHA five-speed transaxle is a constant-mesh manual transaxle that is synchronized in all gear ranges,including reverse.
The transaxle consists of three major sub-assemblies:• Input shaft• Output shaft• Differential assembly
The transaxle shift system consists of the following components:• Mechanical shift cover• Shift rails• Shift forks• Shift cables
OperationThe following are the details of the manual transaxle:
NeutralEngine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. Since no synchro-nizers are engaged on either the input or output shafts, power is not transmitted to the output shafts, power is nottransmitted to the output shaft and the differential does not turn.
1st GearEngine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft firstgear is integral to the input shaft, and is in constant mesh with the intermediate shaft first speed gear. Because ofthis constant mesh, the output shaft first speed gear freewheels until first gear is selected. As the gearshift lever ismoved to the first gear position, the 1-2 fork moves the 1-2 synchronizer sleeve towards first gear on the outputshaft. The synchronizer sleeve engages the first gear clutch teeth, engaging the gear to the output shaft, and allow-ing power to transmit through the output shaft to the differential.

2nd GearEngine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaftsecond gear is integral to the input shaft, and is in constant mesh with the output shaft second speed gear. Becauseof this constant mesh, the output shaft second speed gear freewheels until second gear is selected. As the gearshiftlever is moved to the second gear position, the 1-2 fork moves the 1-2 synchronizer sleeve towards second gear onthe output shaft. The synchronizer sleeve engages the second gear clutch teeth, engaging the gear to the outputshaft, and allowing power to transmit through the output shaft to the differential.
3rd GearEngine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft thirdspeed gear is in constant mesh with the output shaft 3-4 cluster gear which is fixed to the output shaft. Because ofthis constant mesh, the input shaft third speed gear freewheels until third gear is selected. As the gearshift lever ismoved to the third gear position, the 3-4 fork moves the 3-4 synchronizer sleeve towards third gear on the inputshaft. The synchronizer sleeve engages the third gear clutch teeth, engaging the gear to the input shaft, and allowingpower to transmit through the output shaft to the differential.
4th GearEngine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft fourthspeed gear is in constant mesh with the output shaft 3-4 cluster gear which is fixed to the output shaft. Because ofthis constant mesh, the input shaft fourth speed gear freewheels until fourth gear is selected. As the gearshift leveris moved to the fourth gear position, the 3-4 fork moves the 3-4 synchronizer sleeve towards fourth gear on the inputshaft. The synchronizer sleeve engages the fourth gear clutch teeth, engaging the gear to the input shaft, and allow-ing power to transmit through the output shaft to the differential.
5th GearEngine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaft fifthspeed gear is pressed on to the input shaft, and is in constant mesh with the output shaft fifth speed gear. Becauseof this constant mesh, the output shaft fifth speed gear freewheels until fifth gear is selected. As the gearshift leveris moved to the fifth gear position, the 5-R fork moves the 5-R synchronizer sleeve towards the output shaft fifthspeed gear. The synchronizer sleeve engages the fifth gear clutch teeth, engaging the gear to the input shaft, andallowing power to transmit through the output shaft to the differential.
Reverse GearEngine power is transmitted to the input shaft via the clutch assembly and the input shaft turns. The input shaftreverse gear integral to the input shaft, and is in constant mesh with the reverse idler gear. The reverse idler gear,which reverses the rotation of the output shaft, is in constant mesh with the output shaft reverse gear. Because ofthis constant mesh, the output shaft reverse gear freewheels until reverse gear is selected. As the gearshift lever ismoved to the reverse gear position, the 5-R fork moves the 5-R synchronizer sleeve towards the output shaft reversegear. The synchronizer sleeve engages the reverse gear clutch teeth, engaging the gear to the output shaft, andallowing power to transmit through the output shaft to the differential.

DIAGNOSIS & TESTINGAbnormal Transaxle NoiseTransaxle noise is most often a result of worn or damaged components. Chipped, broken gear or synchronizer teeth,and worn bearings all cause noise.
Inspect the following:• Insufficient lubrication• Incorrect lubricant• Miss-assembled or damaged internal components• Improper operation
Symptom Diagnostics
Hard Shifting• Hard shifting may be caused by a mis-adjusted crossover cable. If hard shifting is accompanied by gear clash,
synchronizer clutch and stop rings or gear teeth may be worn or damaged.
Slips Out Of Gear• Transaxle disengagement may be caused by misaligned or damaged shift components, or worn teeth on the
drive gears or synchronizer components. Incorrect assembly also causes gear disengagement.
Low Lubricant Level• Insufficient transaxle lubricant is usually the result of leaks, or inaccurate fluid level check or refill method. Vehi-
cle must be level to accurately check fluid level. Leakage is evident by the presence of fluid around the leakpoint. If leakage is not evident, the condition is probably the result of an under fill.
• If air-powered lubrication equipment is used to fill a transaxle, be sure the equipment is properly calibrated.Equipment out of calibration can lead to an under fill condition.
Clutch Problems• Worn, damaged, or misaligned clutch components can cause difficult shifting, gear clash, and noise.• A worn or damaged clutch disc, pressure plate, or a faulty slave cylinder can cause hard shifting and gear
clash.
Abnormal Noise• Transaxle noise is most often a result of worn or damaged components. Chipped, broken gear or synchronizer
teeth, and worn bearings all cause noise.
Inspect the following:
− Insufficient lubrication− Incorrect lubricant− Improperly assembled or damaged internal components

GENERAL INFORMATIONDescription
The hydraulic clutch system consists of a clutch master cylinder (2), slave cylinder (3), and an interconnectinghydraulic fluid line. Hydraulic fluid is supplied by the clutch system via the clutch master cylinder reservoir (1).
OperationThe clutch hydraulic system is responsible for engaging and disengaging the clutch. Depressing the clutch pedaldevelops fluid pressure in the clutch master cylinder. This pressure is transmitted to the integral release bearingwhich is in contact with the pressure plate diaphragm spring. As additional force is applied, the bearing depresses thediaphragm spring fingers inward on the fulcrums. The action moves the pressure plate rearward, relieving clampingforce on the clutch disc.

Clutch Master Cylinder
DescriptionThe clutch master cylinder mounts to the clutch pedaland consists of a piston and cylinder housing, an actu-ating push rod, and an interconnecting hydraulic tube.Fluid is supplied to the clutch master cylinder via thebrake fluid reservoir.
OperationWhen the clutch pedal is depressed, the push rod moves the piston in the master cylinder, displacing fluid throughthe hydraulic line and into the release bearing. As the release bearing extend it is forced into the fingers of the clutchdiaphragm springs. As the fingers move, they release the clamping pressure on the clutch disc between the clutchpressure plate and the flywheel. The clutch becomes disengaged as this pressure is released. When the clutch pedalis released, the system hydraulic pressure is released. This allows the force of the clutch diaphragm springs to returnthemselves to their original position, re-clamping the clutch disc between the flywheel and the clutch pressure plate.Also, the release bearing is forced to return, which reverses the movement of the hydraulic system and returns thepedal to its original position against the up stop.

OperationThe strut assembly cushions the ride of the vehicle, controlling vibration, jounce and rebound of the suspension. Thecoil spring controls ride quality and maintains proper ride height. The spring isolators isolate the coil spring at the topand bottom from coming into metal-to-metal contact with the upper mounting seat and the strut. The strut dampensjounce and rebound motions of the coil spring and suspension.
Diagnosis & TestingBefore removing the front strut, perform the following to test the front strut functionality:• Adjust the tire pressure to all tires to proper specifications.• Push and shake the front of the vehicle three or four times with identical force every time• During the pushing and recoiling, the resistance and recoil times of the vehicle should be equal.• If the strut (shock absorber) functions properly, the vehicle will recoil several times and then stop recoiling after
the pushing force is removed.
Removal & Installation
CAUTION:At no time when servicing a vehicle can a sheet metal screw, bolt or other metal fastener beinstalled into the strut tower to take the place of an original plastic clip. Also, do not drill holes inthe front strut tower for the installation of any metal fasteners.1. Open the engine hood.2. Raise and support the vehicle.3.

Front Coil Spring
DescriptionA coil-over front strut assembly supports each front coil spring. The top of the strut assembly mounts to the struttower.
OperationCoil springs are designed to store energy and subsequently release it and to absorb shock and maintain a forcebetween contacting surfaces. Coil springs are rated for specific vehicle applications.
NOTE :Each component is serviced by removing the strut assembly from the vehicle and disassembling it. Coil springs arerated separately for each corner or side of the vehicle depending on optional equipment and type of vehicle service.If a coil spring requires replacement, be sure that it is replaced with a spring meeting the correct load rating for thevehicle and its specific options.
Removal & Installation
CAUTION:At no time when servicing a vehicle can a sheet metal screw, bolt or other metal fastener beinstalled into the strut tower to take the place of an original plastic clip. Also, do not drill holes intothe front strut tower for the installation of any metal fasteners into the strut tower area indicated.1.

GENERAL INFORMATIONDescriptionVehicle wheel alignment is the positioning of all interrelated front and rear suspension angles. These angles affect thehandling and steering of the vehicle when it is in motion. Proper wheel alignment is essential for efficient steering,good directional stability, and proper tire wear.
The method of checking a vehicle’s front and rear wheel alignment varies depending on the manufacturer and typeof equipment used. The manufacturer’s instructions should always be followed to ensure accuracy of the alignment.On this vehicle, the suspension angles that can be adjusted are as follows:
Front-axle
• Camber• Toe-in• Caster
Rear-axle
• Camber• Toe-in
Check the wheel alignment and make all wheel alignment adjustments with the vehicle standing at its proper curbheight specification. Curb height is the normal riding height of the vehicle. It is measured from a certain point on thevehicle to the ground or a designated area while the vehicle is sitting on a flat, level surface.
Operation
Curb Height MeasurementThe wheel alignment is to be checked and all alignment adjustments made with the vehicle at its required curb heightspecification.• Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack.• The tires are to be inflated to the recommended pressure.• All tires are to be the same size as standard equipment.• Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.• Vehicle height is not adjustable.• If the measurement is not within specifications, inspect the vehicle for bent or weak suspension components.• Compare the parts tag on the suspect coil spring(s) to the parts book and the vehicle sales code, checking for
a match.• Once removed from the vehicle, compare the coil spring height to a new or known good coil spring. The
heights should vary if the suspect spring is weak.
NOTE :Prior to reading the curb height measurement, the front and rear of the vehicle must be jounced to settle the sus-pension. Induce jounce by pushing down on the center of the bumper (fascia), using care not to damage the vehicle,moving the vehicle up and down, gradually increasing the suspension travel with each stroke. Release the bumper atthe bottom of each stroke, repeating this action several times. Perform this to both front and rear suspensions anequal amount of times.
Pre-Wheel Alignment InspectionBefore any attempt is made to change or correct the wheel alignment, the following inspection and necessary cor-rections must be made to the vehicle to ensure proper alignment.
1. Verify the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height ofthe vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equip-ment.
10
10–36Chery Automobile Co., Ltd.
3. Check the tires on the vehicle. The tires are to beinflated to the recommended air pressure. All tiresmust be the same size and in good condition withapproximately the same tread wear.
4. Check the front tire and wheel assemblies for excessive radial runout.5. Inspect all suspension component fasteners for looseness and proper torque.6. Inspect all ball joints and all steering linkage for looseness and any sign of wear or damage.7. Inspect the rubber bushings on all the suspension components for signs of wear or deterioration. If any bushings
show signs of wear or deterioration, they should be replaced prior to aligning the vehicle.8. Check vehicle curb height.
Wheel Alignment Setup1. Position the vehicle on an alignment rack.
2. Install all required alignment equipment on the vehicle, per the alignment equipment manufacturer’s instructions.On this vehicle, a four-wheel alignment is recommended.
3. Read the vehicle’s current front and rear alignment settings. Compare the vehicle’s current alignment settings tothe vehicle specifications for camber, caster and toe-in.
NOTE :Prior to reading the vehicle’s alignment readouts, the front and rear of vehicle should be jounced. Induce jounce (rearfirst, then front) by grasping the center of the bumper and jouncing each end of vehicle an equal number of times.The bumper should always be released when vehicle is at the bottom of the jounce cycle.

DIAGNOSIS & TESTINGVehicle InspectionVisual inspection of the vehicle is recommended prior to road testing or performing any other procedure. Raise thevehicle on a suitable hoist.
Inspect the following:• Inspect tires and wheels for damage, mud packing and unusual wear; correct if necessary.• Check and adjust tire air pressure to the pressure listed on the label attached to the driver’s door opening.
Tire and Wheel VibrationTire and wheel imbalance, runout and force variation can cause vehicles to exhibit steering wheel vibration.
NOTE :Balance equipment must be calibrated and maintained per equipment manufacturer’s specifications.
Tire Wear PatternsTire wear patterns can be traced to the following tire conditions:• Under inflation will cause wear on the shoulders of tire.• Over inflation will cause wear at the center of tire.• Excessive camber causes the tire to run at an angle to the road. One side of tread is then worn more than the
other.• Excessive toe-in or toe-out causes wear on the tread edges and a feathered effect across the tread.
NOTE :Tread wear indicators are molded into the bottom of the tread grooves. When tread depth is 1.6 mm, the tread wearindicators will appear as a band. Tire replacement is necessary when indicators appear in two or more grooves or iflocalized balding occurs.
Wheel Out-Of-Round Inspection• Raise vehicle and securely support it.• Attach a dial indicator on the edge of rim and measure its unevenness.• Replace the rim if necessary.
NOTE :On both edges of the rim, the maximum allowed average value of the unevenness should not exceed the following:

OperationTurning of the steering wheel is converted into linear travel through the meshing of the helical pinion teeth with therack teeth within the steering gear. The lateral travel pushes and pulls the tie rods to change the direction of thevehicle’s front wheels.
Power assist steering is provided by a belt driven rotary pump. It directs fluid through power steering fluid hoses tothe power steering gear where it is used to assist the driver’s turning effort.
Manual steering control of the vehicle can be maintained if power steering assist is lost. However, under this condi-tion, steering effort is significantly increased.
WARNING!
Power steering fluid, engine components and the exhaust system may be extremely hot if the engine has beenrunning. Do not start the engine with any loose or disconnected hoses. Do not allow hoses to touch the hotexhaust manifold or catalyst. Fluid level should be checked with the engine off to prevent personal injury frommoving parts.

Removal & InstallationWARNING!
Before servicing the steering column, the airbag system must be disarmed. Failure to do so may result in acci-dental deployment of the airbag and possible personal injury (See Airbag System Disarming Procedure in Sec-tion 14 Restraints).
NOTE :To help maintain alignment of the spiral cable connector during reassembly, apply a small piece of tape to the spiralcable and the steering column to keep them in alignment.
1. Set the front wheels to straight-ahead position.2. Disconnect the negative battery cable.3. Remove the driver airbag (See Driver Airbag Removal & Installation in Section 14 Restraints).4. Disconnect the spiral cable electrical connector.5. Remove the steering wheel lock nut (1).
(Tighten: Steering wheel lock nut to 35 ± 5 N·m)
6. Using the steering wheel puller, remove the steering wheel.7. Installation is in the reverse order of removal.
Installation Notes:
• The spiral cable could be damaged if installed in an improper position.• Do not rotate the spiral cable quickly or beyond the limit of turns (this can cause the cable to break).• Verify the airbag system is operating properly after the repair is complete.
Inspection - Hydraulic System1. Steering Wheel Free-Play Inspection
• Set the front wheels to straight-ahead position with the engine idling (hydraulic system is working).
VISM110013
11–12 Chery Automobile Co., Ltd.
• Slightly turn steering wheel to the right and left, and before the wheels begin turning, measure the freeplay of steering wheel.Maximum Limit: 40 mm.
• If the free play exceeds the limit value, inspect the gap between the steering shaft joint and the steeringlinkage, repair or replace the related parts as necessary. If the free play still exceeds the limit value, turnthe steering wheel to the right position with the engine off. Apply 5 N·m of load to the steering wheel andinspect the free-play again.(Standard value: Less than 15 mm steering wheel free play with the engine off)
• If free play exceeds standard value, remove steering gear housing and inspect the gross torque of piniongear.
2. Static Steering Force Inspection• Park the vehicle on a level surface, and turn the steering wheel to the straight-ahead position. Start the
engine, adjust engine speed to 1000 ± 100 RPM.
CAUTION:After adjusting the engine speed, return it back to standard idle speed.
• Connect a spring scale to the outer circle of steering wheel. Measure the steering force required whenturning the steering wheel leftward and rightward (within 1.5 circles) at straight-ahead position. If obvioussteering force fluctuation exists, inspect the steering force as necessary.
− Standard steering force: Less than 34 N·m− Fluctuation tolerance: Less than 5.9 N·m
• If the measured force exceeds the standard value, see the trouble shooting section for inspection andadjustment.
3. Steering Wheel Return to Center InspectionNOTE: This test shall be performed during a road test. The following procedures should be performed during theroad teat:
• Make smooth turns and sharp turns. Check the driving �sense� to ensure there is no difference between the leftand right turns in terms of steering force and the steering wheel returning to center.
• When the vehicle speed is between 20 to 30 km/h turn the steering wheel 90° for 1 or 2 seconds and releasethe steering wheel. If the steering wheel returnsover 70°, the steering wheel return function can beconsidered good.
NOTE :When rapidly turning the steering wheel, there will be a sense of “heavy”, however, this does not indicate a problemwith the steering system (this is due to insufficient steering fluid supplied to the steering fluid pump during idlespeed).

GENERAL INFORMATIONDescriptionThe Electronic Power Steering (EPS) system provides power steering assist to the driver by replacing the conven-tional hydraulic valve system with an electric motor coupled to the steering shaft. The motor is controlled by the EPScontrol unit that senses the steering effort through the use of a torque sensor mounted between the steering columnshaft and the steering gear. Steering assist is provided in proportion to the steering input effort and vehicle speed.
The EPS system consists of these major components:• Steering Wheel (1)• Steering Column (2)• EPS Motor (3)• Steering Clutch• EPS Module (4)• Steering Torque Sensor• Wheel Speed Sensor• Steering Direction Sensor• Steering Gear Assembly (5)
VISM110006

11–30Chery Automobile Co., Ltd.
OperationThe vehicle speed, which is sent by the Engine Control Module (ECM) over the CAN bus, provides the necessaryvehicle speed information to the electronic power steering system to determine the amount or level of power assist.As vehicle speed increases, the amount of power assist provided by the system is reduced to improve and enhanceroad feel at the steering wheel. If the vehicle speed is missing or out of range, the Electronic Power Steering (EPS)control unit defaults to a reduced level of assist. If the vehicle speed returns to the correct in-range values, the EPScontrol unit adjusts the steering assist level accordingly.
The EPS control unit manages the electronic power steering system. The power steering control unit receives vehiclespeed information from the ECM via the CAN bus, the unit also receives information from the steering shaft torquesensor to determine the amount of assist that is needed. At lower speeds, the control unit will provide greater assist.At higher speeds, the control unit will provide less assist. The power steering control unit is part of the steeringcolumn and is not serviceable separately.

GENERAL INFORMATIONDescriptionThe Electronic Power Steering (EPS) control unit manages the electronic steering system. The EPS control unitreceives vehicle speed information from the Engine Control Module (ECM) via the CAN bus, the EPS control unitalso receives information from the steering shaft torque sensor to determine the amount of assist that is needed. Atlower speeds, the EPS control unit will provide greater assist. At higher speeds, the EPS control unit will provide lessassist. The power steering control unit is part of the steering column and is not serviced separately.
OperationThe Electronic Power Steering (EPS) control unit is self-monitoring and has the capability of setting DTCs. If a faultoccurs in the system, the EPS control unit will set a DTC. Depending on the DTC set, the EPS control unit will enterinto a safe mode and will provide a set amount of assist to the steering system.

DIAGNOSIS & TESTINGDiagnostic Help1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the Electronic Power
Steering (EPS) control unit through the data network.2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.3. If the Diagnostic Trouble Code (DTC) cannot be deleted, it is a current fault.4. Use a digital multimeter to perform voltage readings on electronic systems.5. Refer to Technical Bulletins that have been issued.6. Visually inspect the related wiring harness.7. Inspect and clean all EPS control unit grounds that are related to the most current DTC.8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage
supply circuits that may apply to the DTC.
Intermittent DTC TroubleshootingIf the failure is intermittent perform the following:• Check for loose connectors.• Look for any chafed, pierced, pinched, or partially broken wires.• Monitor the scan tool data relative to this circuit.• Wiggle the related wiring harness and connectors while looking for an interrupted signal on the affected circuit.• If possible, try to duplicate the conditions under which the DTC set.• Look for the data to change or for the DTC to reset during the wiggle test.• Look for broken, bent, pushed out or corroded terminals.• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age, or foreign material.• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.• Remove the EPS from the troubled vehicle and install in a new vehicle and test. If the DTC cannot be deleted,
the EPS control unit is malfunctioning. If the DTC can be deleted, return the EPS control unit to the originalvehicle.
Ground InspectionGround connections are very important to the proper operation of electrical and electronic circuits. Ground connec-tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwantedresistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasticallyaffect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following wheninspecting a ground connection:
1. Remove the ground bolt or screw.2. Inspect all mating surface for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for �add-on� accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires
are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, makesure no excess wire insulation has been crimped creating a bad ground.
Electronic Power Steering (EPS) System Maintenance SpecificationThe Electronic Power Steering (EPS) system is a highly accurate and high-powered steering system.
In order to ensure all of the capability and enhance the service life of the steering system, the following guidelinesshould be followed:
1. Keep the battery in good condition: If the battery voltage is low, it will cause hard steering effort.2. All electrical connectors should be properly connected: Proper connector connections will keep moisture and
heat away from the terminals.3. The harness of the EPS system should be routed independently: To ensure the voltage supply capability, the
EPS system harness should be separate from the other electronic control system harnesses.
11–59 Chery Automobile Co., Ltd.
4. The EPS control unit should not be placed in a wet or a high temperature environment.5. When the steering wheel is at the maximum steering angle, and the steering gear reaches the end of its travel,
electrical current reaches the maximum. The EPS control unit and the EPS actuator will heat quickly under thiscondition. When turning the steering wheel, pay attention not to turn it to the maximum position. When this con-dition cannot be avoided, the maximum time that the steering should be held to the maximum is 3 seconds.Damage to steering components could occur if the time is exceeded.

GENERAL INFORMATIONDescriptionThe power steering pump uses hydraulic pressure to operate the power steering gear. The power steering pump isa belt driven droop-flow type power steering pump.
OperationThe power steering pump is mounted to the engine and driven by the engine accessory drive belt. Power steeringfluid enters the pump from the reservoir. The power steering fluid is then trapped between the pump vanes andmoved to the high-pressure side of the pump creating a flow of fluid. The restriction of this flow by the steering gearcreates the pressure that provides the steering assist.

CAUTION:• Use DOT 4 brake fluid or equivalent from a tightly sealed container. Do not use petroleum-based
fluids, which would cause seal damage in the brake system.• Brake fluid will damage painted surfaces. If brake fluid is spilled on any painted surfaces, wash
it off immediately with water.• Never use gasoline, kerosene, alcohol, motor oil, transmission fluid or any fluid containing min-
eral oil to clean system components. These fluids damage rubber cups and seals.• During service procedures, grease or any other foreign material must be kept off the caliper
assembly, brake linings, brake rotor and external surfaces of the hub.• When handling the brake rotor and caliper, be careful to avoid damaging the brake rotor and
caliper, and scratching or nicking the brake shoe lining.
OperationApplying the brake pedal uses lever action to push a rod into the brake booster, which through the use of vacuum,boosts the force of the rod and then transmits this force into the master cylinder. This produces hydraulic pressure inthe master cylinder. On vehicles not equipped with an Antilock Brake System (ABS), the hydraulic pressure is trans-mitted by brake fluid through the brake tubes to the individual brake calipers or wheel cylinders. On vehiclesequipped with ABS, the hydraulic pressure is transmitted by brake fluid through the brake tubes to the ABS HydraulicControl Unit (HCU), which then distributes that pressure to the individual brake calipers and wheel cylinders. Thebrake calipers use hydraulic pressure to apply the brake pads. The application of the brake pads or shoes will causethe rotation of the wheels to slow or stop depending on how much brake pressure is applied. The parking brakescarry out the same function except that they are mechanically actuated by a cable that connects only to the rearbrakes.

DIAGNOSIS & TESTINGDiagnostic HelpBrake diagnosis involves determining if the concern is related to a mechanical, hydraulic, electrical or vacuum oper-ated component.
NOTE :The brake reservoir fluid level will decrease in proportion to normal lining wear.
NOTE :Brake fluid tends to darken over time. This is normal and should not be mistaken for contamination.
NOTE :Before starting repairs which do not require battery power:• Turn off ignition switch.• Disconnect the negative battery terminal.
Preliminary Brake Check:• Check the condition of the tires and wheels. Damaged wheels and worn, damaged or under inflated tires can
cause a pull, shudder, vibration and a condition similar to brake grab.• If a complaint was based on noise while braking, check the suspension components. Jounce the front and the
rear of vehicle and listen for anything that might be caused by a loose, worn or damaged suspension or steer-ing component.
• Inspect the brake fluid level and condition.1. If the fluid level is abnormally low, look for any evidence of leaks at the calipers, brake lines, master cyl-inder and at the Antilock Brake System (ABS) Hydraulic Control Unit (HCU).2. If the fluid appears to be contaminated, drain a sample to examine.
• The system will have to be flushed if the fluid is separated into layers, or contains a substance other thanbrake fluid. The system seals, cups, hoses, master cylinder and HCU will also have to be replaced after flush-ing. Use clean brake fluid to flush the system.
• Check the parking brake operation. Verify free movement and full release of the cables and the lever. Also noteif the vehicle was being operated with the parking brake partially applied.
• Check the brake pedal operation. Verify that the pedal does not bind and has adequate free play. If the pedallacks free play, check the pedal and the power booster for looseness or for a binding condition. DO NOT roadtest the vehicle until the condition is located and corrected.
• Check the vacuum booster check valve and vacuum supply hose.• If the preliminary checks appear to be OK, road test the vehicle.
Diagnosing Intermittent DTCsWhen diagnosing intermittent DTCs observe the following guide lines:• �Changing� components is not the recommended method to diagnosis an intermittent DTC.• An intermittent DTC is usually caused by chafed, pierced, pinched, or partially broken wires.
There are three ways to isolate an intermittent fault:• Perform a self-check to confirm if the DTC is repeatable.• Allow the engine to reach normal operating temperature.• Drive the vehicle and road test on specific road surfaces to allow any loose components to vibrate to verify the
intermittent faults.• Monitor the scan tool data relative to the circuit in question and wiggle test the wiring and connectors. Look for
the data to change or for the DTC to reset during the wiggle test.

Brake Bleeding Procedure
Brake Bleeding InformationWARNING!
When bleeding the brake system, wear safety glasses. A clear bleed tube must be attached to the bleederscrews and submerged in a clear container filled partially with clean brake fluid. Direct the flow of brake fluidaway from yourself and the painted surfaces of the vehicle. Brake fluid at high pressure may come out of thebleeder screws when opened.
CAUTION:Before removing the master cylinder cap, wipe it clean to prevent dirt and other foreign matterfrom dropping into the master cylinder reservoir. Use brake fluid or an equivalent from a fresh,tightly sealed container. Brake fluid must conform to DOT 4 specifications.
NOTE :During the brake bleeding procedure, be sure the brake fluid level remains close to the �MAX� level in the mastercylinder fluid reservoir. Check the fluid level periodically during the bleeding procedure and add brake fluid asrequired.
NOTE :Do not pump the brake pedal at any time while having a bleeder screw open during the bleeding process. This willonly increase the amount of air in the system and make additional bleeding necessary. Do not allow the mastercylinder reservoir to run out of brake fluid while bleeding the system. An empty reservoir will allow additional air intothe brake system. Check the fluid level frequently and add fluid as needed. The following wheel circuit sequence forbleeding the brake hydraulic system should be used to ensure adequate removal of all trapped air from the hydraulicsystem.
Brake Bleeding ProcedureThe following wheel circuit sequence for bleeding the brake hydraulic system should be used to ensure adequateremoval of all trapped air from the hydraulic system:• Left rear wheel• Right front wheel• Right rear wheel• Left front wheel
12–10 Chery Automobile Co., Ltd.
Manual Bleeding
NOTE :To bleed the brakes manually, the aid of a helper will be required.
Attach a clear plastic hose to the bleeder screw andfeed the hose into a clear jar containing enough freshbrake fluid to submerge the end of the hose.
1. Turn the ignition switch off.2. Have a helper pump the brake pedal three or four times and hold it in the down position.3. With the pedal in the down position, open the bleeder screw at least one full turn.4. Once the brake pedal has dropped, close the bleeder screw. After the bleeder screw is closed, release the
brake pedal.5. Repeat the above steps until all trapped air is removed from that wheel circuit (usually four or five times).6. Bleed the remaining wheel circuits in the same manner until all air is removed from the brake system. Monitor
the fluid level in the master cylinder reservoir to make sure it does not go dry.7. Check and adjust brake fluid level to the �MAX� mark.8. Check the brake pedal travel. If pedal travel is excessive or has not been improved, some air may still be
trapped in the system. Re-bleed the brakes as necessary.9. Test drive the vehicle to verify the brakes are operating properly and pedal feel is correct.
Pressure Bleeding
NOTE :Follow pressure bleeder manufacturer’s instructions for use of pressure bleeding equipment.
Attach the pressure bleeding equipment to the mastercylinder.
Attach a clear plastic hose to the bleeder screw andfeed the hose into a clear jar containing enough freshbrake fluid to submerge the end of the hose.
1. Turn the ignition switch off.2. Open the bleeder screw at least one full turn or more to obtain a steady stream of brake fluid.3. After approximately 120-240 ml of fluid have been bled through the brake circuit and an air-free flow is main-
tained in the clear plastic hose and jar, close the bleeder screw.4. Repeat this procedure at all the remaining bleeder screws.5. Check and adjust brake fluid level to the �MAX� mark on the reservoir.6. Check the brake pedal travel. If pedal travel is excessive or has not been improved, some air may still be
trapped in the system. Re-bleed the brakes as necessary.7. Test drive the vehicle to verify the brakes are operating properly and pedal feel is correct.

DescriptionThe master cylinder body is an anodized aluminum casting. It has a machined bore to accept the master cylinderpistons and also has threaded ports with seats for hydraulic brake tube connections. The master cylinder has thebrake fluid reservoir mounted on top of it and supplies brake fluid to the master cylinder as required. The brake fluidreservoir also feeds the clutch hydraulic circuit. The reservoir is made of clear plastic and it houses the brake fluidlevel switch.
OperationWhen the brake pedal is pressed, the master cylinder pistons apply brake pressure through the chassis brake tubesto each brake assembly. The brake fluid reservoir supplies the brake hydraulic system with the necessary fluid tooperate properly.
Removal & Installation
CAUTION:The vacuum in the power brake booster must be pumped down before removing the master cyl-inder to avoid damaging the master cylinder and to prevent the booster from sucking in any con-tamination. This can be done by pumping the brake pedal while the engine is not running until afirm brake pedal is achieved.1. Turn the ignition switch off.2. Siphon out as much brake fluid as possible from the master cylinder.3. With the engine off, pump the brake pedal 4-5 strokes until the pedal feel is firm.4. Disconnect the negative battery cable.5. Disconnect the brake fluid level switch electrical connector at the brake fluid reservoir.6. Disconnect the brake tubes (1) at the master cylin-
der outlet ports. Install plugs at all of the openbrake tube outlets on the master cylinder.(Tighten: Brake tube nuts to 10 ± 1 N·m)

OperationWhen the brakes are applied, fluid pressure is exerted against the caliper piston. The fluid pressure is exertedequally and in all directions. This means pressure exerted against the caliper piston and within the caliper bores willbe equal. Fluid pressure applied to the pistons is transmitted directly to the inboard brake pad. This forces the padlining against the inner surface of the disc brake rotor. At the same time, fluid pressure within the piston bores forcesthe caliper to slide inward on the slide pins. This action brings the outboard brake pad lining into contact with theouter surface of the disc brake rotor.
Removal & Installation1. Using a brake pedal holding tool, depress the brake pedal past its first 25 mm of travel and hold it in this posi-
tion. This will isolate the master cylinder from the brake hydraulic system and will not allow the brake fluid todrain out of the master cylinder reservoir when the lines are opened.

InspectionExcessive runout or wobble in a rotor can increase pedal travel due to piston knock-back. This increases guide pinsleeve wear due to the tendency of the caliper to follow the rotor wobble.
Braking Surface InspectionLight braking surface scoring and wear is acceptable. If heavy scoring or warping is evident, the rotor must be resur-faced or replaced. Excessive wear and scoring of the rotor can cause improper lining contact on the rotor’s brakingsurface. If the ridges on the rotor are not removed before new brake linings are installed, improper wear of the shoeswill result. Some discoloration or wear of the rotor surface is normal and does not require resurfacing when liningsare replaced. If cracks or burned spots are evident, the rotor must be replaced.
Rotor Minimum ThicknessMeasure the rotor thickness (1) at the center of thebrake pad contact surface. Replace the rotor (2) if it isworn below minimum thickness or if machining the rotorwill cause its thickness to fall below specifications.
CAUTION:Do not machine the rotor if it will cause the rotor to fall below minimum thickness.

GENERAL INFORMATIONDescription
This Antilock Brake System (ABS) uses components of the base brake system, but also features the following com-ponents:• Hydraulic Control Unit (HCU) and Antilock Brake System (ABS) Module• Wheel Speed Sensors (wheel speed sensor) - Four sensors (one sensor at each wheel making it a four-chan-
nel system)
The purpose of the ABS is to prevent wheel lockup under braking conditions on virtually any type of road surface.Antilock braking is desirable because a vehicle that is stopped without locking the wheels retains directional stabilityand some steering capability. This allows the driver to retain greater control of the vehicle during braking.

Operation
ABS Braking
• ABS operation is activated when the ABS hydraulic control module senses a wheel lock-up condition. If a wheellock-up is detected during a brake application, the brake system enters the ABS mode. During ABS braking,hydraulic pressure in the four wheel circuits is modulated to prevent any wheel from locking. Each wheel circuitis designed with a set of electric solenoids to allow modulation. The system can build and release pressure ateach wheel, depending on signals generated by the wheel speed sensors at each wheel and received at theABS hydraulic control module.
• There are a few performance characteristics of the ABS that may at first seem abnormal, but in fact are nor-mal. These characteristics are described below.
− If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative andthe ABS warning lamp turns on.
− During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This isnormal.
− Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, orsnow-covered (fresh, deep snow) roads.

DIAGNOSIS & TESTING
Diagnostic Help
Diagnostic Help1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronic
modules through the class two serial data circuit.2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.3. If the Diagnostic Trouble Code (DTC) cannot be deleted, it is a current fault.4. Use a digital multimeter to perform voltage readings on electronic systems.5. Refer to any Technical Bulletins that may apply to the failure.6. Visually inspect the related wiring harness.7. Perform a voltage drop test on the related circuits between the suspected component and the ABS module.8. Inspect and clean all ECM, ABS, engine, and chassis grounds that are related to the most current DTC.9. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage
supply circuits that may apply to the DTC.10. For any wheel speed sensor DTCs, inspect for dirt/metal debris.11. Use the scan tool to perform a System Test if one applies to the failed component.
Intermittent DTC TroubleshootingIf the failure is intermittent perform the following:• Check for loose connectors.• Look for any chafed, pierced, pinched, or partially broken wires.• Monitor the scan tool data relative to this circuit.• Wiggle the related wiring harness and connectors while looking for an interrupted signal on the affected circuit.• If possible, try to duplicate the conditions under which the DTC set.• Look for the data to change or for the DTC to reset during the wiggle test.• Look for broken, bent, pushed out or corroded terminals.• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age or foreign material.• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.• Remove the ABS module from the troubled vehicle and install in a new vehicle and test. If the DTC can not be
deleted, the ABS module is malfunctioning. If the DTC can be deleted, return the ABS module to the originalvehicle.
Ground InspectionGround connections are very important to the proper operation of electrical and electronic circuits. Ground connec-tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwantedresistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasticallyaffect an electronically controlled circuit. A poor or corroded ground can affect the circuit.
Perform the following when inspecting a ground connection:
1. Remove the ground bolt or screw.2. Inspect all mating surfaces for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for �add-on� accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires
are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, makesure no excess wire insulation has been crimped creating a bad ground.

Antilock Brake System (ABS) Bleeding Procedure
ABS Bleeding InformationWARNING!
When bleeding the brake system, wear safety glasses. A clear bleed tube must be attached to the bleederscrews and submerged in a clear container filled partially with clean brake fluid. Direct the flow of brake fluidaway from yourself and the painted surfaces of the vehicle. Brake fluid at high pressure may come out of thebleeder screws when opened.
CAUTION:Before removing the master cylinder cap, wipe it clean to prevent dirt and other foreign matterfrom dropping into the master cylinder reservoir. Use brake fluid or an equivalent from a fresh,tightly sealed container. Brake fluid must conform to DOT 4 specifications.
NOTE :During the brake bleeding procedure, be sure the brake fluid level remains close to the �MAX� level in the mastercylinder fluid reservoir. Check the fluid level periodically during the bleeding procedure and add brake fluid asrequired.
NOTE :Do not pump the brake pedal at any time while having a bleeder screw open during the bleeding process. This willonly increase the amount of air in the system and make additional bleeding necessary. Do not allow the mastercylinder reservoir to run out of brake fluid while bleeding the system. An empty reservoir will allow additional air intothe brake system. Check the fluid level frequently and add fluid as needed. The following wheel circuit sequence forbleeding the brake hydraulic system should be used to ensure adequate removal of all trapped air from the hydraulicsystem.
ABS Bleeding InstructionsWhen bleeding the ABS system, the following bleeding sequence must be followed to ensure complete and adequatebleeding:1. Make sure all hydraulic fluid lines are installed and properly torqued.2. Connect the X-431 scan tool to the Data Link Connector.3. Using the scan tool, check to make sure the ABS module does not have any fault codes stored. If it does,
clear them.4. Bleed the base brake system (See Manuel Brake Bleeding In Section 12 Brakes).
NOTE :Pressure bleeding is recommended to bleed the base brake system to ensure all air is removed from the brakesystem.5. Using the scan tool, access ABS bleeding. Follow the instructions displayed. When finished, disconnect the
scan tool and proceed.6. Bleed the base brake system a second time. Check brake fluid level in the reservoir periodically to prevent
emptying, causing air to enter the hydraulic system.7. Fill the master cylinder fluid reservoir to the �MAX� level.8. Test drive the vehicle to be sure the brakes are operating correctly and that the brake pedal does not feel
spongy.

Manual Bleeding Instructions
NOTE :To bleed the brakes manually, the aid of a helper will be required.
Attach a clear plastic hose to the bleeder screw andfeed the hose into a clear jar containing enough freshbrake fluid to submerge the end of the hose.
1. Turn the ignition switch off.2. Have a helper pump the brake pedal three or four times and hold it in the down position.3. With the pedal in the down position, open the bleeder screw at least one full turn.4. Once the brake pedal has dropped, close the bleeder screw. After the bleeder screw is closed, release the
brake pedal.5. Repeat the above steps until all trapped air is removed from that wheel circuit (usually four or five times).6. Bleed the remaining wheel circuits in the same manner until all air is removed from the brake system. Monitor
the fluid level in the master cylinder reservoir to make sure it does not go dry.7. Check and adjust brake fluid level to the �MAX� mark.8. Check the brake pedal travel. If pedal travel is excessive or has not been improved, some air may still be
trapped in the system. Re-bleed the brakes as necessary.9. Test drive the vehicle to verify the brakes are operating properly and pedal feel is correct.
Pressure Bleeding Instructions
NOTE :Follow pressure bleeder manufacturer’s instructions for use of pressure bleeding equipment.
Attach the pressure bleeding equipment to the MasterCylinder.
Attach a clear plastic hose to the bleeder screw andfeed the hose into a clear jar containing enough freshbrake fluid to submerge the end of the hose.
1. Open the bleeder screw at least one full turn or more to obtain a steady stream of brake fluid.2. After approximately 120-240 ml of fluid have been bled through the brake circuit and an air-free flow is main-
tained in the clear plastic hose and jar, close the bleeder screw.3. Repeat this procedure at all the remaining bleeder screws.4. Check and adjust brake fluid level to the �MAX� mark on the reservoir.5. Check the brake pedal travel. If pedal travel is excessive or has not been improved, some air may still be
trapped in the system. Re-bleed the brakes as necessary.6. Test drive the vehicle to verify the brakes are operating properly and pedal feel is correct.

DIAGNOSIS & TESTINGParking Brake Warning LightThe parking brake switch is part of the circuit for the red warning lamp in the dash panel. The switch will cause thelamp to illuminate only when the parking brakes are applied. If the lamp remains on after parking brake is released,the switch or circuit is faulty.
Parking Brake OperationThe leading cause of improper parking brake operation, is excessive clearance between the parking brake shoes andthe shoe braking surface. Excessive clearance is a result of lining and/or drum wear, drum surface machined over-size.
In most cases, the actual cause of an improperly functioning parking brake (too loose/too tight/won’t hold), can betraced to a parking brake component.
Inspect the following when diagnosing a parking brake problem:• Brake shoe wear• Drum surface (in rear rotor) machined oversize• Front cable not secured to lever• Rear cable not attached to actuator• Rear cable seized• Parking brake lever not seated• Parking brake lever bind
Parking Brake AdjustmentAdjust the parking brake only if the parking brake lever can be pulled up more than 3 notches without having anadequate solid braking effect.
NOTE :Excessive parking brake lever travel (sometimes described as a loose lever or too loose condition) could be theresult of worn brake shoes, improper brake shoe adjustment, or improperly assembled brake parts. A too-loose con-dition can also be caused by inoperative or improperly assembled parking brake components. Always confirm that theparking brake components are assembled properly. Perform the following procedure to adjust the parking brake:
1. Verify the parking brake lever is in the released (down) position.2. Raise and support the vehicle.3. Remove the wheel mounting nuts and the rear tire and wheel assemblies.4. Using the access hole (1) in the rotor, use a suitable tool to adjust the brake shoes.

GENERAL INFORMATIONDescriptionAll models are equipped with a common Heating, Ventilation and Air Conditioning (HVAC) housing assembly thatcombines A/C and heating capabilities into a single unit mounted within the passenger compartment. The HVAChousing assembly consists of three separate housings:• HVAC housing — The HVAC housing is mounted to the dash panel behind the instrument panel and contains
the A/C evaporator. The HVAC housing has mounting provisions for the air inlet housing, blower motor and theair distribution housing.
• Air distribution housing — The air distribution housing is mounted to the rear of the HVAC housing and con-tains the heater core, blend-air and mode-air doors and door linkage.
• Air inlet housing — The air inlet housing is mounted to the passenger side end of the HVAC housing. The airinlet housing contains the recirculation-air door and actuator.
OperationThe A/C system is designed for the use of a non-CFC, R-134a refrigerant and uses an A/C evaporator to cool anddehumidify the incoming air prior to blending it with the heated air. A temperature control determines the discharge airtemperature by operating the temperature control cable, which moves the blend-air door. This allows an almostimmediate control of the output air temperature of the system. The mode door cable operates the mode-air doorswhich direct the flow of the conditioned air out the various air outlets, depending on the mode selected. Whenequipped with A/C, the recirculation door actuator operates the recirculation-air door which closes off the fresh airintake and recirculates the air already inside the vehicle. The electric recirculation door actuator and the blower motorare connected to the vehicle electrical system by the instrument panel wire harness. The blower motor controls thevelocity of air flowing through the HVAC housing assembly by spinning the blower wheel within the HVAC housing atthe selected speed by use of the blower motor resistor, which is located in the dash panel in the engine compart-ment.
The air distribution housing must be removed from the HVAC housing and disassembled for service of the blend-airand mode-air doors. The air inlet housing must be removed from HVAC housing and disassembled for service of therecirculation-air door. The HVAC housing must be removed from the vehicle and disassembled for service of the A/Cevaporator.

GENERAL INFORMATIONDescriptionThe A/C refrigerant lines and pipes are used to carry the refrigerant between the various A/C system components.
Any kinks or sharp bends in the refrigerant lines and hoses will reduce the capacity of the entire A/C system and canreduce the flow of refrigerant within the system.
OperationHigh pressure is produced in a refrigerant system when the A/C compressor is operating. Extreme care must beexercised to make sure that each of the refrigerant system connections is pressure-tight and leak free. It is a goodpractice to inspect all flexible hose refrigerant lines at least once a year to make sure they are in good condition andproperly routed. Depending on vehicle, model and market application, refrigerant lines are connected to each other orother A/C system components with block-type or quick-connect type fittings. To ensure the integrity of the refrigerantsystem, O-rings and/or gaskets may be used to seal the refrigerant system connections. The refrigerant lines andhoses cannot be repaired and must be replaced if leaking or damaged.
WARNING!
The A/C system contains refrigerant under high pressure. Repairs should only be performed by qualified servicepersonnel. Serious or fatal injury may result from improper service procedures.If an accidental A/C system discharge occurs, ventilate the work area before resuming service. Large amounts ofrefrigerant released in a closed work area will displace the oxygen and cause suffocation and serious or fatalinjury.
CAUTION:• Never add R-12 to a refrigerant system designed to use R-134a. Do not use R-12 equipment or
parts on an R-134a A/C system. These refrigerants are not compatible and damage to the A/Csystem will result.
• Do NOT run the engine while using a vacuum pump on the A/C system or with a vacuum presentwithin the A/C system. Failure to follow this caution will result in serious A/C compressor dam-age.
• Do not overcharge the refrigerant system. Overcharging will cause excessive compressor headpressure and can cause compressor noise and A/C system failure.

DIAGNOSIS & TESTINGA/C Compressor Noise TestingWhen investigating an A/C system related noise, you must first know the conditions under which the noise occurs.These conditions include: weather, vehicle speed, transaxle in gear or neutral, engine speed, engine temperature,and any other special conditions. Noises that develop during A/C operation can often be misleading. For example:what sounds like a failed bearing, may be caused by loose bolts, nuts, mounting brackets or a loose compressorassembly.
NOTE :The A/C compressor must be replaced if any unusual noise is heard from the compressor itself.
NOTE :Drive belts are speed sensitive. At different engine speeds and depending upon drive belt tension, drive belts candevelop noises that are mistaken for an A/C compressor noise. Improper drive belt tension can cause a misleadingnoise when the compressor is operating at maximum displacement, which may not occur when the compressor is atminimum displacement.
1. Select a quiet area for testing.2. Duplicate the complaint conditions as much as possible.3. Turn the A/C system On and Off several times to clearly identify any compressor noise.4. Listen to the A/C compressor while it is operating at maximum and minimum displacement.5. Probe the A/C compressor with an engine stethoscope or a long screwdriver with the handle held to your ear to
better localize the source of the noise.6. To duplicate high-ambient temperature conditions (high head pressure), restrict the air flow through the A/C con-
denser. Install a manifold gauge set or a scan tool to be certain that the discharge pressure does not exceed2600 kPa.
7. Check the condition of the accessory drive belt.NOTE: The A/C compressor must be replaced if the drive hub is broken or if the compressor shaft does notrotate smoothly.
8. Check the compressor hub and pulley and bearing assembly. Be certain that the hub and pulley are properlyaligned and that the pulley bearing is mounted securely to the A/C compressor. .
9. Check the refrigerant system plumbing for incorrect routing, rubbing or interference, which can cause unusualnoises. Also check the refrigerant lines and hoses for kinks or sharp bends that will restrict refrigerant flow, whichcan cause noises.
10. Loosen all of the compressor mounting hardware and retighten.CAUTION:Do NOT run the engine with a vacuum pump in operation or with a vacuum present within theA/C system. Failure to follow this caution will result in serious A/C compressor damage.
11. If the noise is from opening and closing of the high pressure relief valve, recover, evacuate and recharge therefrigerant system, If the high pressure relief valve still does not seat properly, replace the A/C compressor.
12. If the noise is from liquid refrigerant slugging in the A/C suction line, replace the A/C accumulator and check therefrigerant oil level and the refrigerant system charge.
13. If a slugging condition still exists after replacing the A/C accumulator, then replace the A/C compressor.
Refrigerant System LeaksWARNING!
R-134a service equipment or vehicle A/C system should not be pressure tested or leak tested with compressedair. Mixture of air and R-134a can be combustible at elevated pressures. These mixtures are potentially danger-ous and may result in fire or explosion causing property damage, personal injury or death. Avoid breathing A/Crefrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved serviceequipment meeting SAE requirements to discharge an R-134a system. If accidental system discharge occurs,ventilate work area before resuming service.
13
13–35Chery Automobile Co., Ltd.
NOTE :If the A/C refrigerant system charge is empty or low, a leak in the A/C system is likely. Visually inspect all A/C lines,fittings and components for an oily residue. Oil residue can be an indicator of an A/C system leak location.
NOTE :The only way to correctly determine if the refrigerant system is fully charged with R-134a is to completely evacuateand recharge the A/C system.
Refrigerant System Empty1. Evacuate the refrigerant system to the lowest degree of vacuum possible . Determine if the system holds a vac-
uum for 15 minutes. If vacuum is held, a leak is probably not present. If system will not maintain vacuum level,proceed to STEP 2.
2. Prepare and dispense 0.3 kilograms of R-134a refrigerant into the evacuated refrigerant system and proceed toSTEP 1 of the System Low procedure.
Refrigerant System Low1. Position the vehicle in a wind-free work area. This will aid in detecting small leaks.2. Operate the heating-A/C system with the engine at idle under the following conditions for at least 5 minutes:
Doors or windows openTransaxle in Park or Neutral with the parking brake set (depending on application)HVAC control panel set to outside airFull coolPanel modeHigh blower
€ A/C compressor engaged3. Shut the vehicle off and wait 2 - 7 minutes. Then use an electronic leak detector that is designed to detect
R-134a refrigerant and search for leaks. Fittings, lines or components that appear to be oily usually indicate arefrigerant leak. To inspect the A/C evaporator for leaks, insert the leak detector probe into the drain tube open-ing or an air outlet. A dye for R-134a is available to aid in leak detection. Use only approved refrigerant dye.
CAUTION:A leak detector only designed for R-12 refrigerant will not detect leaks in an R-134a refrigerant sys-tem.

A/C System Evacuation
CAUTION:Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/Csystem. Failure to follow this caution will result in serious A/C compressor damage.
NOTE :Special effort must be used to prevent moisture from entering the A/C system oil. Moisture in the oil is very difficultto remove and will cause a reliability problem with the A/C compressor.
If the refrigerant system has been open to the atmosphere, it must be evacuated before the system can be filled.Moisture and air mixed with the refrigerant will raise the compressor high pressure above acceptable operating lev-els. This will reduce the performance of the A/C system and damage the A/C compressor. Moisture will boil at nearroom temperature when exposed to vacuum. To evacuate the refrigerant system:
NOTE :When connecting the service equipment coupling to the line fitting, verify that the valve of the coupling is fully closed.This will reduce the amount of effort required to make the connection.
1. With the engine OFF, connect a suitable refrigerant recovery/recycling station, refrigerant recovery machine or amanifold gauge set with vacuum pump and refrigerant recovery equipment. Do not operate the engine with avacuum on the A/C system.
2. Open the suction and discharge valves and start the vacuum pump. The vacuum pump should run a minimumof 45 minutes prior to charge to eliminate all moisture in system. When the suction gauge reads to the lowestdegree of vacuum possible for 30 minutes, close all valves and turn off vacuum pump. If the system fails toreach specified vacuum, the refrigerant system likely has a leak that must be corrected. If the refrigerant systemmaintains specified vacuum for at least 30 minutes, start the vacuum pump, open the suction and dischargevalves. Then allow the system to evacuate an additional 10 minutes.
3. Close all valves. Turn off and disconnect the vacuum pump.4. Charge the refrigerant system.
A/C System RechargeAfter all refrigerant system leaks have been repaired and the refrigerant system has been evacuated, a refrigerantcharge can be injected into the system.
CAUTION:A small amount of refrigerant oil is removed from the A/C system each time the refrigerant systemis recovered and evacuated. Before charging the A/C system, you MUST replenish any oil lost dur-ing the recovery process.1. Evacuate the refrigerant system (See A/C System Evacuation And Recharge In Section 13 Heating & Air Con-
ditioning).2. A manifold gauge set and an R-134a refrigerant recovery/recycling/refrigerant recovery/recycling station that
meets SAE standard J2210 should be connected to the refrigerant system.3. Open both the suction and discharge valves, then open the charge valve to allow the refrigerant to flow into the
system.

4. When the transfer of refrigerant has stopped, close both the suction and discharge valves.5. If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle
and set the heating-A/C system controls so that the A/C compressor is operating and the blower motor is runningat its lowest speed setting. Run the engine at a steady high idle (approx. 2000 RPM).
6. Open the low-pressure valve to allow the remaining refrigerant to transfer to the refrigerant system.
WARNING!
Take care not to open the discharge (high pressure) valve at this time. Failure to follow this warning could resultin possible personal injury or death.
7. Disconnect the refrigerant recovery/recycling station and manifold gauge set from the refrigerant system serviceports.
8. Reinstall the caps onto the refrigerant system service ports.
Compressor
DescriptionThe A/C system uses a 7-piston incline-disk compressor. The compressor is a variable displacement compressor.The variable displacement compressor has a swash plate that rotates to reciprocate pistons, which compress refrig-erant. The variable displacement compressor changes the swash plate angle to change the refrigerant displacement.The variable displacement compressor manages displacement by controlling refrigerant differential pressure beforeand after a throttle at the discharge side; achieving precise cooling capability in accordance with the cabin environ-ment and driving conditions.
CAUTION:Do NOT run the engine with a vacuum pump in operation or with a vacuum present within the A/Csystem. Failure to follow this caution will result in serious A/C compressor damage.
NOTE :The compressor drive hub and the pulley and bearing assembly cannot be serviced separately from the A/C com-pressor. In the event of drive hub or pulley and bearing assembly damage or failure, the A/C compressor, drive huband pulley and bearing must be replaced as an assembly.
OperationThe A/C compressor is controlled by the Engine Control Module (ECM), depending on engine application. The ECMcalculates compressor displacement required by A/C system load and demand by monitoring vehicle speed, A/C highside pressure, engine speed, evaporator temperature, accelerator pedal position, ambient temperature and A/C-heater request signals. The ECM then sends a pulse width modulated signal to the A/C compressor control solenoidto increase or decrease refrigerant flow through an orifice located within the compressor housing. The amount ofrefrigerant allowed to pass through the orifice in the compressor determines the head pressure which controls theangle of the swash plate, which in turn, determines the amount of compressor displacement. When there is nodemand for A/C, the swashplate is adjusted to nearly a zero degree angle, which removes compressor torque dragfrom the engine.
NOTE :The A/C compressor cannot be repaired and it must be replaced if found inoperative or damaged. If an internal fail-ure of the A/C compressor has occurred, the A/C accumulator and the A/C liquid line must also be replaced.

CAUTION:The A/C accumulator and the A/C liquid line must be replaced if an internal failure of the A/C com-pressor has occurred. Failure to replace the A/C accumulator and the A/C liquid line can causeserious damage to the replacement A/C compressor.
NOTE :When replacing multiple A/C system components, determine how much oil should be removed from the new A/Ccompressor.
NOTE :Replacement of the refrigerant line O-ring seals and gaskets is required anytime a refrigerant line is opened. Failureto replace the rubber O-ring seals and metal gaskets could result in a refrigerant system leak.
1. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).2. Disconnect the A/C compressor electrical connector.3.

Evaporator
DescriptionThe evaporator coil is located in the HVAC housing, under the instrument panel. The evaporator coil is positioned inthe HVAC housing so that all air that enters the housing must pass over the fins of the evaporator before it is dis-tributed through the system ducts and outlets. However, air passing over the evaporator coil fins will only be condi-tioned when the compressor is engaged and circulating refrigerant through the evaporator coil tubes.
OperationRefrigerant enters the evaporator from the orifice tube as a low-temperature, low-pressure liquid. As air flows overthe fins of the evaporator, the humidity in the air condenses on the fins, and the heat from the air is absorbed by therefrigerant. Heat absorption causes the refrigerant to boil and vaporize. The refrigerant becomes a low-pressure gasbefore it leaves the evaporator. The evaporator core housing directs airflow from the blower motor through the evap-orator core and heater core. All airflow from the blower motor passes through the evaporator core. The airflow is thendirected through or around the heater core by the temperature blend door(s).
Removal & Installation1. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).2. Remove the instrument panel (See Instrument Panel Removal & Installation in Section 15 Body & Accessories).3.

5. Installation is in the reverse order of removal.
Installation Notes:
• Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the refriger-ant line fittings.
• Use only the specified O-rings as they are made of a special material for the R-134a system.• Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.• Recharge the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Condition-

Condenser
DescriptionThe condenser is located in the air flow in front of the engine cooling radiator. The condenser transforms the refrig-erant from a gas into a liquid. It is attached to the vehicle with bolts and the A/C lines with fittings.
OperationWhen the refrigerant gas releases its heat, it condenses. When the refrigerant leaves the condenser, it has becomea high-pressure liquid refrigerant. The volume of air flowing over the condenser fins is critical to the proper coolingperformance of the air conditioning system. Therefore, it is important that there are no objects placed in front of theradiator grille openings in the front of the vehicle or foreign material on the condenser fins that might obstruct proper

Active Restraints
• Front Seat Belts• Rear Seat Belts
Passive Restraints
• Driver Airbag• Passenger Airbag• Seat Belt Tensioner
Operation
Active RestraintsThe primary passenger restraints are the seat belts. Seat belts are referred to as an active restraint because thevehicle occupants are required to physically fasten and properly adjust these restraints in order to benefit from them.
Passive RestraintsThe passive restraints are referred to as a supplemental restraint system because they were designed and areintended to enhance the protection for the occupants of the vehicle only when used in conjunction with the seat belts.They are referred to as passive restraints because the vehicle occupants are not required to do anything to makethem operate; however, the vehicle occupants must be wearing their seat belts in order to obtain the maximum safetybenefit from the supplemental restraint system.
The supplemental restraint system electrical circuits are continuously monitored and controlled by a microprocessorand software contained within the Restraints Control Module (RCM). An airbag indicator in the Instrument Clusterilluminates for about seven seconds as a bulb test each time the ignition switch is turned to the ON or START posi-tions. Following the bulb test, the airbag indicator is turned ON or OFF by the RCM to indicate the status of thesupplemental restraint system. If the airbag indicator comes ON at any time other than during the bulb test, it indi-cates that there is a problem in the supplemental restraint system electrical circuits. Such a problem may causeairbags not to deploy when required, or to deploy when not required.
Deployment of the supplemental restraints depends upon the angle and severity of an impact. When an impact issevere enough, the microprocessor in the RCM signals the inflator of the appropriate airbag units to deploy theirairbag cushions. The front seat belt tensioners are provided with a deployment signal by the RCM in conjunction withthe front airbags.

DIAGNOSIS & TESTINGDiagnostic Help1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronic
modules through the data network.2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.3. If the Diagnostic Trouble Code (DTC) cannot be deleted, it is a current fault.4. Use only a digital multimeter to perform voltage readings on electronic systems.5. Refer to any Technical Bulletins that may apply to the failure.6. Visually inspect the related wiring harness.7. Inspect and clean all Restraints Control Module (RCM) grounds that are related to the most current DTC.8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage
supply circuits that may apply to the DTC.
Intermittent DTC TroubleshootingIf the failure is intermittent perform the following:• Check for loose connectors.• Look for any chafed, pierced, pinched, or partially broken wires.• Monitor the scan tool data relative to this circuit.• Wiggle the related wiring harness and connectors while looking for an interrupted signal on the affected circuit.• If possible, try to duplicate the conditions under which the DTC set.• Look for the data to change or for the DTC to reset during the wiggle test.• Look for broken, bent, pushed out or corroded terminals.• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age, or foreign material.• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.• Remove the Restraints Control Module (RCM) from the troubled vehicle and install in a new vehicle and test. If
the DTC cannot be deleted, the RCM is malfunctioning. If the DTC can be deleted, return the RCM to the origi-nal vehicle.
Ground InspectionGround connections are very important to the proper operation of electrical and electronic circuits. Ground connec-tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwantedresistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasticallyaffect an electronically controlled circuit. A poor or corroded ground can affect the circuit. Perform the following wheninspecting a ground connection:
1. Remove the ground bolt or screw.2. Inspect all mating surface for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for �add-on� accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires
are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, makesure no excess wire insulation has been crimped creating a bad ground.
Diagnostic Tools
Diagnostic Scan Tool X-431Read the following when connecting the X-431 scan tool:• Connect the scan tool to the Data Link Connector (DLC) for communication with the vehicle.• The DLC is located on the driver side compartment under the steering column (it is attached to the instrument
panel and accessible from the driver seat).• The DLC is rectangular in design and capable of accommodating up to 16 terminals.• The electrical connector has keying features to allow easy connection.

DTC Confirmation Procedure:Before performing the following procedure, confirm that battery voltage is more than 12 V.• Turn ignition switch off.• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.• Turn the ignition switch on.• With the scan tool, record and erase stored DTCs in the Restraints Control Module (RCM).• Turn ignition switch off, and then turn the ignition switch on.• With the scan tool, select view DTC and data stream in the RCM.• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 14 Restraints for more information).
NOTE :• Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.• If the warning lamp goes out immediately after the warning lamp flashed for 6 - 7 seconds, this indicates that the
system is OK.• If the warning lamp is on for 6 - 7 seconds continuously, then goes out, or the warning lamp is on continuously,
this indicates that there are history DTCs in the system. Use the Scan Tool to erase the DTCs.• If any other condition occurs, use the Scan Tool to erase the history DTCs first, then check the warning lamp. If
the warning lamp does not go out immediately after the warning lamp flashes for 6 - 7 seconds when using theScan Tool, erase the history DTCs first.
• In the course of troubleshooting the airbag system, make sure the system power supply is shut off, and wait twominutes for the system capacitor to discharge.
• The following tools are required to perform the following test:• X-431 Scan Tool• Airbag Special Load Tool• Digital Multimeter• The squib circuit connectors integrate a �shorting� spring (which prevents the airbag from deploying unintentionally
due to static electricity by shorting the positive wire to the negative wire in the squib circuit when the connectorsare disconnected). Therefore, if the airbag electrical connector or spiral cable electrical connector is damaged orimproperly connected, the shorting spring may not be released when the electrical connector is connected.

Go to Diagnostic Procedure - Step 1.• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 14 Restraints for more information).
NOTE :• Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.• If the warning lamp goes out immediately after the warning lamp flashed for 6 - 7 seconds, this indicates that the
system is OK.• If the warning lamp is on for 6 - 7 seconds continuously, then goes out, or the warning lamp is on continuously,
this indicates that there are history DTCs in the system. Use the Scan Tool to erase the DTCs.• If any other condition occurs, use the Scan Tool to erase the history DTCs first, then check the warning lamp. If
the warning lamp does not go out immediately after the warning lamp flashes for 6 - 7 seconds when using theScan Tool, erase the history DTCs first.
• In the course of troubleshooting the airbag system, make sure the system power supply is shut off, and wait twominutes for the system capacitor to discharge.
• The following tools are required to perform the following test:• X-431 Scan Tool• Airbag Special Load Tool• Digital Multimeter• The squib circuit connectors integrate a �shorting� spring (which prevents the airbag from deploying unintentionally
due to static electricity by shorting the positive wire to the negative wire in the squib circuit when the connectorsare disconnected). Therefore, if the airbag electrical connector or spiral cable electrical connector is damaged orimproperly connected, the shorting spring may not be released when the electrical connector is connected.

CAN VEHICLE COMMUNICATIONSDescriptionController Area Network (CAN) communication is a multiplex communication system. The CAN system allows thevehicles electronic components and electronic modules to transmit and receive data. The following electronic com-ponents are located on the CAN network:• Engine Control Module (ECM)• Instrument Cluster (IC)• Antilock Brake System (ABS) Hydraulic Control Module• Yaw Rate Sensor• Front Body Control Module (FBCM)• Spiral Cable• Electronic Power Steering Actuator (if equipped)• Restraints Control Module• HVAC Conditioner Control Unit
OperationThe CAN network uses a twisted pair of circuits to transmit data (+) and data (-). The data (+) and the data (-)circuits are each regulated to approximately 2.5 volts during neutral or rested network traffic. As bus messages aresent on the data (+) circuit, voltage is increased by approximately 1.0 volt. Inversely, the data (-) circuit is reduced byapproximately 1.0 volt when a bus message is sent. Multiple bus messages can be sent over the CAN circuits allow-ing multiple modules to communicate with each other.

DIAGNOSIS & TESTINGDiagnostic Help1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronic
modules through the class two serial data circuit.2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.3. If the DTC cannot be deleted, it is a current fault.4. Use a digital multimeter to perform voltage readings on electronic systems.5. Refer to Technical Bulletins that have been issued.6. Visually inspect the related wiring electrical harness.7. Inspect and clean all FBCM grounds that are related to the DTC.8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage
supply circuits that may apply to the DTC.
Intermittent DTC TroubleshootingIf the failure is intermittent perform the following:• Check for loose connectors.• Look for any chafed, pierced, pinched, or partially broken wires.• Monitor the scan tool data relative to this circuit.• Wiggle the related wiring electrical harness and connectors while looking for an interrupted signal on the
affected circuit.• If possible, try to duplicate the conditions under which the DTC set.• Look for the data to change or for the DTC to reset during the wiggle test.• Look for broken, bent, pushed out or corroded terminals.• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age or foreign material.• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.• Remove the FBCM module from the troubled vehicle and install in a new vehicle and test. If the DTC cannot
be deleted, the FBCM module is malfunctioning. If the DTC can be deleted, return the FBCM module to theoriginal vehicle.
Ground InspectionGround connections are very important to the proper operation of electrical and electronic circuits. Ground connec-tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwantedresistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasticallyaffect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following wheninspecting a ground connection:
1. Remove the ground bolt or screw.2. Inspect all mating surface for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for �add-on� accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires
are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, makesure no excess wire insulation has been crimped creating a bad ground.

DIAGNOSIS & TESTINGDiagnostic Help1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronic
modules through the class two serial data circuit.2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.3. If the DTC cannot be deleted, it is a current fault.4. Use a digital multimeter to perform voltage readings on electronic systems.5. Refer to Technical Bulletins that issued.6. Visually inspect the related wiring electrical harness.7. Inspect and clean all RBCM grounds that are related to the DTC.8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage
supply circuits that may apply to the DTC.
Intermittent DTC TroubleshootingIf the failure is intermittent perform the following:• Check for loose connectors.• Look for any chafed, pierced, pinched, or partially broken wires.• Monitor the scan tool data relative to this circuit.• Wiggle the related wiring electrical harness and connectors while looking for an interrupted signal on the
affected circuit.• If possible, try to duplicate the conditions under which the DTC set.• Look for the data to change or for the DTC to reset during the wiggle test.• Look for broken, bent, pushed out or corroded terminals.• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age or foreign material.• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.• Remove the RBCM module from the troubled vehicle and install in a new vehicle and test. If the DTC cannot
be deleted, the RBCM module is malfunctioning. If the DTC can be deleted, return the RBCM module to theoriginal vehicle.
Ground InspectionGround connections are very important to the proper operation of electrical and electronic circuits. Ground connec-tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwantedresistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasticallyaffect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following wheninspecting a ground connection:
1. Remove the ground bolt or screw.2. Inspect all mating surface for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for �add-on� accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires
are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, makesure no excess wire insulation has been crimped creating a bad ground.

DIAGNOSIS & TESTINGDiagnostic Help1. The X-431 scan tool connects to the Data Link Connector (DLC) and communicates with the vehicle electronic
modules through the class two serial data circuit.2. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.3. If the DTC cannot be deleted, it is a current fault.4. Use a digital multimeter to perform voltage readings on electronic systems.5. Refer to any Technical Bulletins that issued.6. Visually inspect the related wiring electrical harness.7. Inspect and clean all Immobilizer grounds that are related to the DTC.8. If numerous trouble codes were set, use a wiring schematic and look for any common ground circuits or voltage
supply circuits that may apply to the DTC.
Intermittent DTC TroubleshootingIf the failure is intermittent, perform the following:• Check for loose connectors.• Look for any chafed, pierced, pinched, or partially broken wires.• Monitor the scan tool data relative to this circuit.• Wiggle the related wiring electrical harness and connectors while looking for an interrupted signal on the
affected circuit.• If possible, try to duplicate the conditions under which the DTC set.• Look for the data to change or for the DTC to reset during the wiggle test.• Look for broken, bent, pushed out or corroded terminals.• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as dam-
age or foreign material.• A data recorder, and/or oscilloscope should be used to help diagnose intermittent conditions.
Ground InspectionGround connections are very important to the proper operation of electrical and electronic circuits. Ground connec-tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwantedresistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drasticallyaffect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following wheninspecting a ground connection:
1. Remove the ground bolt or screw.2. Inspect all mating surface for tarnish, dirt, rust, etc.3. Clean as required to assure good contact.4. Reinstall bolt or screw securely.5. Inspect for �add-on� accessories which may be interfering with the ground circuit.6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires
are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, makesure no excess wire insulation has been crimped creating a bad ground.

EXTERIOR LAMPSDescriptionThe exterior lamps consist of the following:• Headlamps• Turn Signal Lamps• Fog Lamps• Stop Lamps• Backup Lamps• Position Lamps
Operation• Headlamps: With the light switch in the 2nd position, the Front Body Control Module (FBCM) receives input
requesting head lamp operation. The FBCM then supplies power to the head lamps.• Turn Signal Lamps: When the turn signal switch is in LH or RH position with the ignition switch in ON position,
the FBCM detects the RH or LH turn signal request. The FBCM supplies power to the respective turn signallamp.
• Hazard Lamps: When the hazard switch is in ON position, the FBCM detects the hazard switch signal. TheFBCM outputs the flasher signal (right and left). The FBCM then activates the hazard indicator and audiblebuzzer.
• Fog Lamps: When the front/rear fog lamp switch is in ON position and also the light switch is in the 1st or 2ndposition. The FBCM/RBCM receives input requesting fog lamp operation. The FBCM/RBCM then supplies powerto the fog lamps.
• Stop Lamps: When the brake pedal is applied, the stop lamp switch sends the signal to the RBCM. The RBCMthen supplies power to the stop lamps.
• Backup Lamps: When the FBCM receives the signal from the backup lamp switch. The FBCM then sends asignal to the RBCM, then the RBCM supplies power to the backup lamp.

MIRRORSDescriptionThe mirrors are controlled by a single switch assembly located on the driver’s door trim panel. A three-position switchselects the right or left power mirror for adjustment. A momentary joystick directional switch allows the driver to adjustthe selected power mirror in the Up & Down or Right & Left directions. The heated mirror system is controlled byFront Body Control Module (FBCM). When there is water vapor on the mirrors, the heated mirrors will eliminate thewater vapor.
OperationUse the mirror select switch, located on the driver’s door trim panel, to adjust the view obtained in the outside mir-rors. Rotate the joystick for Left or Right mirror selection. Select a mirror and press the joystick that correspond withthe direction that you want the mirror to move.

PARKING SONARDescriptionWhen the transaxle selector lever is in the �R� position, a stationary object will be detected by the rear sonar sensorcausing the sonar buzzer to sound a tone. As the vehicle moves closer to the object, the rate of the tone willincrease. When the object is very close to the vehicle, the tone will sound continuously.
OperationWith power and ground supplied, transaxle gear selector lever in �R� position, the rear sonar sensor will detect obsta-cles within 1.5 m of the rear sonar sensors. The sensor signal inputs are transmitted to the Rear Body Control Mod-ule (RBCM) and the Front Body Control Module (FBCM). The RBCM and the FBCM communicate this signal to theinstrument cluster via CAN communication to activate the buzzer. The vehicle operator is notified of obstacles by avaried rate of tone from the sonar buzzer depending on the distance of the obstacle being sensed.

GENERAL INFORMATIONDescriptionThe wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harnessrouting and retention, connector pin-out information and location views for the various wiring harness components,splices and grounds.
Electrical SchematicsThe electrical schematics are grouped into individual service manual chapters. If a component is most likely found ina particular group, it will be shown complete (all wires, connectors, and pins) within that group. For example, theEngine Control Module (ECM) is most likely to be found in Chapter 03 (Electronic Engine Controls), so it is shownthere complete. It can, however, be shown partially in another group if it contains some associated wiring.
Chery electrical schematics are designed to provide information regarding the vehicles wiring content. In order toeffectively use the wiring diagrams to diagnose and repair Chery vehicles, it is important to understand the followingfeatures and characteristics:• Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the page, and the
ground (B-) side of the circuit is placed near the bottom of the page.• All switches, components, and modules are shown in the at rest position with the doors closed and the key
removed from the ignition.• Components are shown with a solid line around the component.• It is important to realize that no attempt is made on the diagrams to represent components and wiring as they
appear on the vehicle. For example, a short piece of wire is treated the same as a long one.• Switches and other components are shown as simply as possible, with regard to function only.

ELECTRICAL TROUBLESHOOTINGTroubleshooting Wiring ProblemsWhen troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed andexplained below. Always check for non-factory equipped components added to the vehicle before doing any diagno-sis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of theproblem.
Perform the following when troubleshooting a wiring problem:
1. Verify the problem.2. Verify any related symptoms (do this by performing operational checks on components that are in the same
circuit).3. Analyze the symptoms (use the wiring diagrams to determine what the circuit is doing, where the problem most
likely is occurring and where the diagnosis will continue).4. Isolate the problem area.5. Repair the problem area.6. Verify the proper operation (for this step, check for proper operation of all items on the repaired circuit).
Testing For Voltage1. Connect the ground lead of a voltmeter to a known good ground.2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON
to check voltage. Refer to the appropriate test procedure.
Testing For Continuity1. Remove the fuse for the circuit being checked or, disconnect the battery.2. Connect one lead of the ohmmeter to one side of the circuit being tested.3. Connect the other lead to the other end of the circuit being tested (low or no resistance means good continuity).
Testing For A Short To Ground1. Remove the fuse and disconnect all items involved with the fuse.2. Connect a test light or a voltmeter across the terminals of the fuse.3. Starting at the fuse block, wiggle the wiring harness about six to eight inches apart and watch the voltmeter/test
light.4. If the voltmeter registers voltage or the test light glows, there is a short to ground in that general area of the
wiring harness.
Intermittent and Poor ConnectionsMost intermittent electrical problems are caused by faulty electrical connections or wiring. It is also possible for asticking component or relay to cause a problem. Before condemning a component or wiring assembly, check thefollowing items:• Connectors are fully seated• Spread terminals, or terminal push out• Terminals in the wiring assembly are fully seated into the connector/component and locked into position• Dirt or corrosion on the terminals (any amount of corrosion or dirt could cause an intermittent problem)• Damaged connector/component casing exposing the item to dirt or moisture• Wire insulation that has rubbed through causing a short to ground• Some or all of the wiring strands broken inside of the insulation• Wiring broken inside of the insulation

ELECTRICAL TROUBLESHOOTING TOOLSJumper Wires• A jumper wire is used to create a temporary circuit.
Connect the jumper wire between the terminals ofa circuit to bypass a switch.
CAUTION:Do not connect a jumper wire from the powersource line to a body ground. This may causeburning or other damage to wiring harnessesor electronic components.
Voltmeter• The DC voltmeter is used to measure circuit volt-
age. A voltmeter with a range of 15 V or more isused by connecting the positive (+) probe (red leadwire) to the point where voltage will be measuredand the negative (-) probe (black lead wire) to abody ground.

Ohmmeter• The ohmmeter is used to measure the resistance
between two points in a circuit and to check forcontinuity and short circuits.
CAUTION:Do not connect the ohmmeter to any circuitwhere voltage is applied. This will damage theohmmeter.

ELECTRICAL REPAIRWire Repair
NOTE :When splicing a wire it is important that the correct gage be used.
1. Remove one-half (1/2) inch of insulation from each wire that needs to be spliced.2. Place a piece of adhesive lined heat shrink tubing on one side of the wire. Make sure the tubing will be long
enough to cover and seal the entire repair area.3. Place the strands of wire overlapping each other inside of the splice clip.4. Using a crimping tool, crimp the splice clip and wires together.
NOTE :Do not use acid core solder when making wiring repairs.
5. Solder the connection together using a soldering iron and rosin core type solder only.6. Center the heat shrink tubing over the joint and heat using a heat gun. Heat the joint until the tubing is tightly
sealed and sealant comes out of both ends of the tubing.
Fuse Replacement• When replacing a fuse, be sure to replace it with
one of the same capacity. If a fuse fails again, thecircuit probably has a short and the wiring shouldbe checked.
• Be sure the negative battery terminal is discon-nected before replacing a main fuse.
• When replacing a pullout fuse, use the fuse puller.
