| STEP | CHECK TO BE PERFORMED | RESOLUTION IF THE CHECK IS NOT OK |
|---|
| 1 | Press the START/STOP button and turn off the engine.Disconnect the wiring harness connector from the timing sensor.Press the START/STOP button.Check that the voltage across pin 1 of the control unit See K047 TIMING SENSOR and earth is between 4.8 and 5.2 V | Repair or if necessary replace the electrical wiring between the timing sensor and the engine control unit See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 2 | Check that the voltage across pin 1 and 3 of the sensor See K047 TIMING SENSOR is between 4.8 and 5.2 VMove on to Step 4 | Move on to Step 3 |
| 3 | Repair any faults in the wiring between the engine control unit and the timing sensor See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT The test can be considered over | Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
| 4 | Check that the voltage across pin 2 of the control unit See K047 TIMING SENSOR and earth is between 4.8 and 5.2 V | Move on to Step 3 |
| 5 | Check for faults in the timing sensor, such as intermittent contacts, missing teeth, reference point or incorrect gap | Restore correct operation.Replace the timing sensor if necessaryOp. 5510CG CHECK ON OPERATION OF TIMING SENSOR |
| 6 | Replace the timing sensorOp. 5510CG CHECK ON OPERATION OF TIMING SENSORand check the fault has disappeared.The test can be considered over | Repair the original timing sensor and replace the engine management control unit. Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
