Was bedeutet der Fehlercode?

The CPM has registered a break in the cable to the water pump, so the signal is missing. The cause may be a broken cable, poor connections, or a pump that is blocked or damaged. The heater cannot be activated until the code has been cleared.

Mögliche Ursachen

Open circuit in the cable between the CPM and the water pump
Contact resistance, oxidation or loose connections
Blocked water pump
Damaged water pump

Was Sie tun können

1Clear the code and try starting the heater again
2If you have a diagnostic tool, activate the water pump; if it does not start, the fault is probably permanent, while a pump that starts points to an intermittent fault
3Check the connectors at the heater and at the water pump: they should be secure and free from oxidation
4Use a multimeter to confirm voltage at the water pump connector when the heater starts; if it is missing, the cable is a likely cause
5If there is no fault in the cables or connectors the pump may be blocked: have a workshop check it and replace the water pump if needed

Symptome, die Sie bemerken können2
