939010185 - 1060EB FLOW MODULATOR SOLENOID OPERATION CHECK
| 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 cable loom connector from the flow modifying solenoid valve.Press the START/STOP button.Check that the voltage across pin 6 of the solenoid See L064 FLOW MODIFYING SOLENOID VALVEand the earth is greater than 11 V.Move on to Step 4 | Move on to Step 2 |
| 2 | Press the START/STOP button.In the engine compartment junction unitremove fuse F11 (third from the right in the bottom row).Press the START/STOP button.Check the voltage between the inlet contact of fuse F11 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 faults are found, restore the wiring between the junction unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT If necessary, replace the wiring. The test may be considered complete | Replace the junction unit Op. 5505A13 ADDITIONAL JUNCTION UNIT IN ENGINE COMPARTMENT - R.R. |
| 4 | Check that the voltage across pin 6 and 2 of the solenoid See L064 FLOW MODIFYING SOLENOID VALVEis greater than 11 V.Move on to Step 6 | Move on to Step 5 |
| 5 | If faults are found, restore the wiring between the engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT Replace the wiring if necessaryThe test can be considered over | Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
| 6 | Press the START/STOP button.Disconnect the wiring harness connector from engine control unit connector BPress 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. | Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 7 | Press the START/STOP button.Check that the voltage across pin 45 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 engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 8 | Check that the voltage across pin 45 of the control unit See M010 ENGINE MANAGEMENT ECU and pin 1 of the solenoid See L064 FLOW MODIFYING SOLENOID VALVEis less than 5 Ohms | Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 9 | Press the START/STOP button.Check that the voltage across pin 35 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 engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 10 | Press the START/STOP button.Check that the voltage across pin 35 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 engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 11 | Check that the voltage across pin 35 of the control unit See M010 ENGINE MANAGEMENT ECU and pin 5 of the solenoid See L064 FLOW MODIFYING SOLENOID VALVEis less than 5 Ohms | Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT |
| 12 | Replace the flow bypass solenoidOp. 1060E20 and check the fault has disappeared | Restore the original solenoid valve and replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
