199002999 - 1080CB EGR SOLENOID OPERATION CHECK
| CHECK TO BE PERFORMED | RESOLUTION IF THE CHECK IS NOT OK | |
|---|---|---|
| 1 | Turn the ignition key OFF.Disconnect the wiring harness connector from the EGR solenoid See L030 EGR SOLENOID VALVE Turn the ignition key ON.Measure the voltage between Pin 5 of the wiring side connector and Earth. Ensure it is greater than 11V.Turn the ignition key OFF.Move on to Step 4 | Move on to Step 2 |
| 2 | In the engine compartment junction unit, remove fuse F27 (fourth from the top in the left row) See B001 JUNCTION UNIT Turn the ignition key ON.Check the voltage between the fuse inlet contact and earth. Ensure it is greater than 11 V. | Replace the junction unit Op. 5505A13 ADDITIONAL JUNCTION UNIT IN ENGINE COMPARTMENT - R.R. |
| 3 | If fualts are present, repair or if necessary replace the electrical wiring between the engine compartment junction unit and the solenoid. See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT The test can be considered over | Replace the junction unit Op. 5505A13 ADDITIONAL JUNCTION UNIT IN ENGINE COMPARTMENT - R.R. |
| 4 | Disconnect the wiring harness connector from engine control unit connector B See M010 ENGINE MANAGEMENT ECU Turn the ignition key ON.Measure the voltage between Pin 1 (wiring side) of the EGR solenoid wiring side connector and Earth. Ensure it is less than 0.3 V. See L030 EGR SOLENOID VALVE | Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 5 | Turn the ignition key OFF.Measure the resistance between Pin 1 (wiring side) of the EGR solenoid valve and earth, checking that it is more than 500 kOhm See L030 EGR SOLENOID VALVE | Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 6 | Measure the resistance between Pin 1 (wiring side) of the EGR solenoid wiring side connector and Pin 60 (wiring side) of engine control unit wiring side connector B. Ensure it is less than 5 Ohms. See L030 EGR SOLENOID VALVE See M010 ENGINE MANAGEMENT ECU Reconnect the wiring harness connectors to the EGR solenoid and the engine control unit See L030 EGR SOLENOID VALVE See M010 ENGINE MANAGEMENT ECU | Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 7 | Replace the solenoid and check that the fault has disappeared Op. 1080C24 E.G.R. SYSTEM SOLENOID - R + R | Repair the original EGR solenoid and replace the engine control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - R.R |
