| STEP | CHECK TO BE PERFORMED | RESOLUTION IF THE CHECK IS NOT OK |
|---|
| 1 | Press the START/STOP button and turn off the engine.Connect the wiring harness connector from the accelerator pedal potentiometerPress the START/STOP button.Select the following system on the diagnostic equipment: Diesel EDC16C39 electronic injection system.Check that error P0641 – Power supply to sensors 1 is “Present”.Move on to Step 5 | Move on to Step 2 |
| 2 | Press the START/STOP button.Disconnect the wiring harness connector from engine control unit connector APress the START/STOP button.Check that the voltage across pin 9 of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V. | Repair or if necessary replace the electrical wiring between the accelerator pedal potentiometer and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 3 | Check that the voltage across pin 30 of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V. | Repair or if necessary replace the electrical wiring between the accelerator pedal potentiometer and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 4 | Replace the accelerator pedal Op. 1068A20 ACCELERATOR PEDAL WITH BUILT-IN POTENTIOMETER - R.R and check the fault has disappeared.The test can be considered over | Repair the original accelerator pedal and replace the engine management control unit. Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
| 5 | Press the START/STOP button.Disconnect the wiring harness connector from the timing sensor.Press the START/STOP button.Select the following system on the diagnostic equipment: Diesel EDC16C39 electronic injection system.Check that error P0641 – Power supply to sensors 1 is “Present”. | Replace the timing sensorOp. 5510C30 ENGINE TIMING SENSOR - R+R |
| 6 | Press the START/STOP button.Disconnect the wiring harness connector from engine control unit connector APress the START/STOP button.Check that the voltage across pin 45 of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V.Move on to Step 8 | Move on to Step 7 |
| 7 | If faults are present, repair or if necessary replace the electrical wiring between the engine control unit and the accelerator pedal potentiometer. See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT Replace the wiring if necessaryThe test can be considered over | Replace the accelerator pedal Op. 1068A20 ACCELERATOR PEDAL WITH BUILT-IN POTENTIOMETER - R.R |
| 8 | Press the START/STOP button.Check that the voltage across pin 30 of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is more than 500 kOhm. | Repair or if necessary replace the electrical wiring between the accelerator pedal potentiometer and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 9 | Disconnect the wiring harness connector from engine control unit connector BPress the START/STOP button. Check that the voltage across Pin 11 of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is greater than 0.3 V. | Repair or if necessary replace the electrical wiring between the timing sensor and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 10 | Press the START/STOP button.Check that the voltage across pin 11 of the control unit See M010 ENGINE MANAGEMENT ECU and the earth is more than 500 kOhm. | Repair or if necessary replace the electrical wiring between the timing sensor and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
