| 1 | Press the START/STOP button and turn off the engine.Disconnect the wiring harness connector from the FAP differential pressure sensor.Press the START/STOP button. Select the following system on the diagnostic instrument: Electronic diesel injection system EDC16C39. Check that error P0697 – Sensor 3 power supply 3 is “Present” | Replace the differential pressure sensor Op. 1080B82 PARTICULATE FILTER DIFFERENTIAL PRESSURE (D.P.F.) SENSOR - R R |
| 2 | Press the START/STOP button.Disconnect the wiring harness connector from the linear sensor. See K120 LINEAR SENSOR FOR FANS Press the START/STOP button.Select the following system on the diagnostic equipment: Diesel EDC16C39 electronic injection system.Check that error P0697 – Power supply to sensors 3 is “Present”. | Replace the linear sensorOp. 5040B20 |
| 3 | 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 44 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 FAP differential pressure sensor and the engine control unit See E5070 PARTICLE FILTER SYSTEM |
| 4 | Press the START/STOP button.Check that the voltage across pin 44 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 FAP differential pressure sensor and the engine control unit See E5070 PARTICLE FILTER SYSTEM |
| 5 | Press the START/STOP button.Check that the voltage across pin 22 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 linear sensor and the engine control unit See E6021 COMPRESSOR ENGAGEMENT - DESCRIPTION |
| 6 | Press the START/STOP button.Check that the voltage across pin 22 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 linear sensor and the engine control unit See E6021 COMPRESSOR ENGAGEMENT - DESCRIPTION |
| 7 | Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R | |
