Was bedeutet der Fehlercode?

The CPM has registered a signal that is too low on the cable to the water pump, meaning the signal sits below where it should be. The cause may be a short circuit to earth in the cable, poor connections or a damaged pump. The heater cannot be activated until the code has been cleared.

Mögliche Ursachen

The cable between the CPM and the water pump is shorted to earth
Contact resistance, oxidation or loose connections
Damaged water pump

Was Sie tun können

1Clear the code and start the heater again
2If you have a diagnostic tool, activate the water pump and listen for a buzzing sound; if there is none, the fault is probably permanent
3Disconnect the connector at the heater and check that the contacts are secure and free from oxidation
4Use a multimeter to check that the cable to the water pump has no contact with earth (the body); if it does, the cable is shorted
5If the fault returns, have a workshop check the water pump and the wiring
