194003938 - 1080CB EGR SOLENOID OPERATION CHECK

CHECK TO BE PERFORMEDRESOLUTION IF THE CHECK IS NOT OK
1Press the START/STOP button and turn off the engine.Disconnect the cable loom connector from the EGR solenoid    See L030 EGR SOLENOID VALVEPress the START/STOP button.Measure the voltage between Pin 1 of the wiring side connector and Earth. Ensure it is greater than 11V.Press the START/STOP button.Move on to Step 4Move on to Step 2
2In the engine compartment junction unit, remove fuse F11 (third in the lower row)    See B001 ENGINE COMPARTMENT JUNCTION UNITPress the START/STOP button.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.
3If 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 MANAGEMENTThe test can be considered overReplace the junction unit    Op. 5505A13 ADDITIONAL JUNCTION UNIT IN ENGINE COMPARTMENT - R.R.
4Disconnect the cable loom connector from engine management control unit connector B    See M010 ENGINE MANAGEMENT CONTROL UNITPress the START/STOP button.Measure the voltage between Pin 2 of the EGR solenoid wiring side connector and Earth. Ensure it is less than 0.3 V.    See L030 EGR SOLENOID VALVERepair or if necessary replace the electrical wiring between the engine control unit and the solenoid    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
5Press the START/STOP button. Measure the resistance between Pin 2 of the EGR solenoid wiring side connector and Earth. Ensure it is greater than 500 kOhm.    See L030 EGR SOLENOID VALVERepair or if necessary replace the electrical wiring between the engine control unit and the solenoid    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
6Measure the resistance between Pin 2 of the EGR solenoid wiring side connector and Pin 60 of engine control unit wiring side connector B. Ensure it is less than 5 Ohms.    See L030 EGR SOLENOID VALVE    See M010 ENGINE MANAGEMENT CONTROL UNITReconnect the cable loom connectors to the EGR solenoid and the engine management control unit    See L030 EGR SOLENOID VALVE    See M010 ENGINE MANAGEMENT CONTROL UNITRepair or if necessary replace the electrical wiring between the engine control unit and the solenoid    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
7Replace the solenoid and check that the fault has disappeared    Op. 1080C24 E.G.R. SYSTEM SOLENOID - R + RRepair the original EGR solenoid and replace the engine management control unit    Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R
