Faults

Faults are declared as either present or stored (depending on whether they appeared in a certain context and havedisappeared since, or whether they remain present but have not been diagnosed within the current context).

The present orstored status of faults should be taken into consideration when the diagnostic tool is used followingthe + after ignition supply being switched on (without acting on the system components).

For a present fault, apply the procedure described in the Interpretation of faults section.

For a stored fault, note the faults displayed and apply the instructions in the Notes section.

If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the fault

If the fault is not confirmed, check: the electrical lines which correspond to the fault, the connectors on these lines (corrosion, bent pins, etc.), the resistance of the component detected as faulty, the condition of the wires (melted or split insulation, wear).

Conformity check

The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because thedata is inconsistent. Therefore, this stage is used to:

carry out fault finding on faults that do not have a fault display, and which may correspond to a customercomplaint.

check that the system is operating correctly and that there is no risk of a fault recurring after repairs.

This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.

If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult thecorresponding fault finding page.

Customer complaints - Fault finding chart

If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be treated bycustomer complaints.

A summary of the overall procedure to follow is provided on thefollowing page in the form of a flow chart.

4. FAULT FINDING PROCEDURE (continued)

Wiring check

Fault finding problemsDisconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is notpresent when the analysis is made (stored fault).

Visual inspectionLook for damage under the bonnet and in the passenger compartment.Carefully check the fuses, insulators and wiring routing.Look for signs of oxidation.

Tactile inspectionWhile manipulating the wiring harness, use the diagnostic tool to note any change in fault status from "stored" to"present".Make sure that the connectors are properly locked.Apply light pressure to the connectors.Twist the wiring harness.If there is a change in status, try to locate the source of the fault.

Inspection of each componentDisconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping onthe insulating section).Make sure that the clips and tabs are properly locked in the sockets.Check that no clips or tabs have been dislodged during connection.Check the clip contact pressure using an appropriate model of tab.

Resistance checkCheck the continuity of entire lines, then section by section.Look for a short circuit to earth, to + 12 V or to another wire.

If a fault is detected, repair or replace the wiring harness.

5. FAULT FINDING LOG

You will always be asked for this log:q when requesting technical assistance from the Techline,q for approval requests when replacing parts for which approval is obligatory,q

to be attached to monitored parts for which reimbursement is requested. The log is needed for warrantyreimbursement, and enables better analysis of the parts removed.

6. SAFETY ADVICE

Safety rules must be observed during any work on a component to prevent any damage or injury: check that the battery is properly charged to avoid damaging the computers with a low load, Use the proper tools.

IMPORTANT

IMPORTANTAny fault on a complex system call for thorough fault finding with the appropriate tools. TheFAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a

record is kept of the procedure carried out. It is an essential document when consulting themanufacturer.

IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDINGIS CARRIED OUT.

Fault finding - Role of components

Role of main automatic transmission components

Automatic transmission computer:The computer is mounted to the gearbox and enables the entire system to be controlled.

Its role is to define the optimum operating mode for the automatic transmission (modify the torque transmitted to thedrive wheels by the automatic transmission), inform the driver (instrument panel, information display, display indicatoron the bridge piece, buzzer) and communicate with the other computers.To carry out this function, the transmission computer takes account of: the operation of the automatic transmission, signals exchanged with other computers, driver requests.

Gearbox oil temperature sensor:Its role is to inform the automatic transmission computer of the gearbox oil temperature.

Gearbox input speed sensorIts role is to inform the automatic transmission computer of the turbine speed.

Gearbox output speed sensor:Its role is to inform the automatic transmission computer of the vehicle speed.

Brake light switch:Its role is to inform the automatic transmission computer that the driver has depressed the brake pedal.

Multifunction switch:Its role is to inform the automatic transmission computer of the gear lever position.

Shift-lock:The purpose of this function is to lock the lever in Park position.

Solenoid valves:The solenoid valves are fitted in the factory and are indissociable from the hydraulic distributor to ensure optimalgearbox operation, so they cannot be replaced separately.The automatic transmission has two types of solenoid valve: 2 "all or nothing" solenoid valves, 7 "progressive" solenoid valves.

Of these 9 solenoid valves, 8 are used to control gear changes in automatic and manual modes, and one controlsthe oil pressure in the automatic gearbox hydraulic distributor.

Fault finding - Function

The automatic transmission computer performs the following functions:

Gearbox operating mode selection:According to the vehicle speed and the driver's command expressed by the accelerator pedal position, the automatic

transmission determines the best moment for the gear change. The automatic transmission computer corrects anydriver errors and inhibits engagement of a gear that would cause the engine to over- or under-rev.

Gear changes:Taking into account the various input factors, the computer will decide whether to actuate the various solenoid valvesto ensure smooth system operation (gearbox clutches, brakes and hydraulics).

The computer is also involved in: the gear change quality, protecting the automatic gearbox in the event of a malfunction.

Declutching when stopped:This function temporarily disables creeping, when the vehicle is stationary with a gear engaged and the brake pedalhas been depressed.

The purpose of this function is to:q reduce fuel consumption,q reduce vehicle vibrations,q reduce vehicle drag to save the hydraulic slave cylinders,q increase the oil service life.

This function is performed by the automatic transmission computer. The automatic transmission computer causes atemporary pressure drop in clutch 1. The clutch 1 solenoid valve is actuated when the operating conditions are met(vehicle stationary, gear engaged and brake pedal depressed).

"CONVERTER LOCKUP" FUNCTION:

Purpose of this function:The purpose of this function is to lock the converter.

Lockup/release definition:The converter is a hydraulic clutch providing a flexible and automatic connection between the engine and theautomatic transmission mechanism: its operation can be broken down into two phases:

q When starting, it multiplies engine torque: CONVERTER FUNCTION.

qAt high speed, it transmits the engine torque: COUPLER FUNCTION. The converter body comprises two half-shells welded together. The converter is coupled to the engine crankshaft

by the drive plate. The converter is continuously filled with oil. The impeller is integral with the converter casing and the engine. The turbine is linked to the turbine shaft transmission mechanism. The stator is placed between the impeller and the turbine.

The purpose of the lockup function is to lock the turbine and the converter casing together, transforming a hydraulicconnection into a mechanical connection. The aim of this is to eliminate problems caused by slippage*, resulting inimproved performance of vehicles with automatic transmission.

slippage*: Slippage means the partial loss of drive power, which results in increased fuel consumption and reducedengine braking.

Fault finding - Replacement of components

Replacing the gearbox computer:Remove the automatic transmission computer(see MR 370 mechanical, 23A, Automatic transmission,Automatic transmission computer, Removal - Refitting).

Refit the automatic transmission computer(see MR 370 mechanical, 23A, Automatic transmission,Automatic transmission computer, Removal - Refitting).

Establish communication with the diagnostic tool.Use command VP001 Enter VIN.Run command VP009 "Write last service operation date".

Do not carry out any automatic programming if replacing the automatic transmission computer. Automaticprogramming is finalised when the vehicle is driven.In order to optimise the automatic programming before delivering the vehicle to the customer, apply the"Programming procedure" shown below.

Replacing the hydraulic distributor:Remove the gearbox hydraulic distributor(see MR 370 mechanical, 23A, automatic transmission, Hydraulicdistributor, Removal - Refitting).

Refit the gearbox hydraulic distributorand the gear selector on the computer (see MR 370 mechanical, 23A,automatic transmission, Hydraulic distributor, Removal - Refitting).

Establish communication with the diagnostic tool.Run command VP009 "Write last service operation date".

Do not carry out any automatic programming if replacing the automatic gearbox hydraulic distributor.Automatic programming is finalised when the vehicle is driven.In order to optimise the automatic programming before delivering the vehicle to the customer, apply the

"Programming procedure" shown below.

PROGRAMMING PROCEDURE:Programming conditions:The automatic gearbox oil temperature should be between 20 C and 100 C (the first time the ignition is switchedon it should be between 60 C and 100 C).Stationary, engine running, brake pedal depressed:

Engage neutral at least 5 times to consolidate the programming.While driving:

Engage the same gear at least 5 times (ie. in the same conditions) to consolidate the programming.

Note:Gear changes are slow and harsh the first few times the vehicle is driven, until the automatic transmission computerhas carried out its automatic programming.During upshifts and downshifts, the system analyses variations in oil pressure, components (play in the brakes andclutches, changes to spring stiffness due to ageing) and input torque, then corrects them in order to maintain thequality of gear changes.The system analyses the turbine speed during the 3 phases of drag reduction (selection of Neutral when stationary,regulation during drag reduction and deselection of Neutral) and corrects this speed by adjusting the converterlockup solenoid valve pressure.
