Was bedeutet der Fehlercode?
The CEM monitors the voltage supply to the fuel pump and the voltage on the cable. The code is stored when the supply cable to the pump has contact with supply voltage, which can stop the pump from working as it should. The engine then does not start, either sometimes or always.
Mögliche Ursachen
- The fuel pump supply cable has contact with supply voltage
Was Sie tun können
- 1Check that the relevant fuses are intact, especially the one for the fuel pump. Their locations are in the owner's manual or on the fuse box cover
- 2Look for chafing on the fuel pump wiring, especially where it may have touched a sharp edge
- 3Use a multimeter to check whether the supply cable to the pump has voltage when the pump should not be switched on
- 4If you have a diagnostic tool: activate the fuel pump and listen for it to start
- 5If the fault returns, have a workshop with diagnostic equipment check the wiring and the control module
