5-7Engine Fault Codes -Ford Models

How to Retrieve Engine FaultCodesWhen a engine malfunction is detected by theElectronic Control Module (ECM), a fault code isrecorded and the check engine light will illuminateat the ground controls. Use the following procedureto retrieve the engine fault code to determine theengine malfunction.

Note: Perform this procedure with the key switch inthe off position.

1 Open the ground controls side cover.

2 Pull out the red Emergency Stop button to theon position at both the ground and platformcontrols. Turn the key switch to groundcontrols.

3 Quickly activate and release the start toggleswitch/button. Do not start the engine.

4 Move and hold the run/test toggle switch to thetest position.

Result: The check engine light should turn on.The check engine light should begin to blink.

5 Continue to hold the run/test toggle switch in thetest position and count the blinks.

Note: Fault codes are two or three digits. Thecheck engine light will blink the first digit of a twodigit code then will pause for 1.2 seconds and thenblink the second digit. For example: the checkengine light blinks 5 consecutive times, pauses for1.2 seconds and then blinks 1 time. That wouldindicate code 51. The ECM is able to store up tosix individual fault codes. There will be a 2.4second pause between codes.

6 Refer to Section 5, Fault Codes, for definition ofengine fault codes.

Note: Once a fault code has been retrieved and therepair has been completed, the ECM memory mustbe reset to clear the fault code from the ECM. SeeHow to Clear Engine Fault Codes from the ECM.

7-12Valve Coils

How to Test a CoilA properly functioning coil provides anelectromagnetic force which operates the solenoidvalve. Critical to normal operation is continuitywithin the coil. Zero resistance or infinite resistanceindicates the coil has failed.

Since coil resistance is sensitive to temperature,resistance values outside specification canproduce erratic operation. When coil resistancedecreases below specification, amperageincreases. As resistance rises above specification,voltage increases.

While valves may operate when coil resistance isoutside specification, maintaining coils withinspecification will help ensure proper valve functionover a wide range of operating temperatures.


Note: If the machine has been in operation, allowthe coil to cool at least 3 hours before performingthis test.

1 Tag and disconnect the wiring from the coil tobe tested.

2 Test the coil resistance using a multimeter setto resistance (Ω). Refer to the Valve CoilResistance Specification table.

Result: If the resistance is not within theadjusted specification, plus or minus 10%,replace the coil.

Valve Coil ResistanceSpecificationNote: The following coil resistance specificationsare at an ambient temperature of 68°F / 20°C. Asvalve coil resistance is sensitive to changes in airtemperature, the coil resistance will typicallyincrease or decrease by 4% for each 18°F / 20°Cthat your air temperature increases or decreasesfrom 68°F / 20°C.

9-4Oscillating Axle Option(after serial number GS9004-41690)

How theOscillating Axle FunctionsWhen driving the GS-90 with the platform in thestowed position, the oscillating axle functionensures that all four wheels maintain solid contactwith the ground, delivering the maximum tractionavailable.When driving the GS-90 with the platform raisedabove the down limit switch height, the oscillatingaxle function is limited in that the oscillatingcylinders only respond to input from the oscillatingaxle limit switches, located on the rear axle.

Oscillate Stowed Relay CR84

Terminal 30 of the Oscillate Stowed relay, CR84,receives power from the Platform Down limitswitch, LS6. When the platform is raised aboveLS6, power to terminal 30 will be cut.

Terminal 86 of CR84 is connected to pin J2-C5 atthe ECM. Pin J2-C5 is powered anytime the BrakeRelease valve coil Y2 is energized, thus energizingCR84 terminal 87 and, ultimately, all four oscillatingvalve coils, allowing oil to pass between theoscillating cylinders. J2-C5 continues to powerterminal 86 for 0.5 seconds after Y2 is de-energized.

Oscillate Raised Relay CR85

Terminal 30 of the Oscillate Raised relay, CR85,receives power from the Power relay, CR42. Whenpower is cut to terminal 86 of CR42 via key switchor either Emergency Stop button, power to terminal30 of CR85 will be lost.

Terminal 86 of CR85 receives continuous powerfrom pin J2-C6 when the ECM is powered until anoutrigger is lowered to the ground, at which pointthe power from J2-C6 is cut.

12-1Platform Overload System

Calibrate the Platform OverloadSystem (if equipped)

On machines with platform overload systems,proper calibration is essential to safe machineoperation. An improperly calibrated platformoverload system could result in the system failingto sense an overloaded platform. The stability ofthe machine is compromised and it could tip over.

Note: Be sure the hydraulic oil level is between thefull and add marks on the oil level indicator.

Note: Perform this procedure with the machine ona firm, level surface that is free of obstructions.

All models:

1 Models with outriggers: Deploy the outriggersand level the machine.

2 Apply a thin layer of dry film lubricant to thearea of the chassis where the scissor arm wearpads make contact.


4 Open the large ground control panel door andlocate connector joining the Electronic ControlModule (ECM) wire harness and the platformcontrols wire harness.

Note: This connection is just below the groundcontrols.



7 Using a suitable lifting device, place a testweight, corresponding to the maximum load asindicated on the capacity indicator decal, in thecenter of the platform floor. Secure the weightto the platform. Refer to the chart below.

GS-3390 1878 kg

GS-4390 1286 kg(most models - refer to capacity indicator decal)

GS-4390 1421 kg(some models - refer to capacity indicator decal)

GS-5390 1410 kg

8 Turn the key switch to platform control and pullout the red Emergency Stop button to the onposition at both the ground and platformcontrols. Start the engine.

9 Raise the platform to approximately 6 m.

10 Release the safety arm latch, lift the safety armand rotate to a vertical position. Lock the safetyarm in position.

43 Engine Coolant Temperature (ECT) sensor low voltage.

ECM detects a excessively low signal voltage from the ECT sensor.

Check engine coolant level OR check for shorted wires or poor terminal connections from the ECT sensor to the ECM OR replace the ECT sensor.

45 Intake Air Temperature (IAT) sensor low voltage.

ECM detects a excessively low signal voltage from the IAT sensor.

The IAT sensor shares the same ground wire as the ECT and MAP sensors. Check for shorted wires or poor terminal connections from the IAT sensor to the ECT and MAP sensors to the ECM OR replace the IAT sensor.

51 Low oil pressure. Bad oil pressure switch, wires shorted to ground or not enough engine oil.

Check engine oil level OR check for shorted wires or poor terminal connections from the oil pressure switch to the ECM OR replace the oil pressure switch.

52 Crankshaft Position (CKP) sensor senses extra or missing pulses.

The CKP and CMP sensors work together; if one is bad, the other one won't work correctly and causes the ECM to detect a fault. The ECM uses the signal pulses from the CKP and CMP sensors to initiate sequential fuel injection.

Check for shorted wires or poor terminal connections from the CKP and CMP sensors to the ECM OR replace the CKP or CMP sensor.

53 Camshaft Position (CMP) sensor senses unknown pattern.

The CMP and CKP sensors work together; if one is bad, the other one won't work correctly and causes the ECM to detect a fault. The ECM uses the signal pulses from the CKP and CMP sensors to initiate sequential fuel injection.

Check for shorted wires or poor terminal connections from the CKP and CMP sensors to the ECM OR replace the CKP or CMP sensor.

54 ECM Fault - Illegal Operation.

The ECM received an illegal instruction signal from one or more of the sensors and has gone into a default program and then return to normal operation.

Replace the ECM.

55 ECM - Illegal Interruption.

The ECM received an illegal interruption signal from one or more engine sensors and has gone into a default program and then return to normal operation.

Replace the ECM.

56 ECM - Computer Operating Properly (COP) failure.

Under normal operation the ECM will store numbers into memory. If this does not happen, it will reset itself and set fault code 56.

Replace the ECM.

61 System voltage low. Battery supply voltage to the ECM is 8V DC or less.

Check battery and/or alternator condition OR check for shorted wires or poor terminal connections from the battery to the ECM.
