Was bedeutet der Fehlercode?

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

Mögliche Ursachen

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

Was Sie tun können

1Clear the code and try starting the heater again
2If you have a diagnostic tool, activate the fuel pump; if it does not start, the fault is probably permanent, while a pump that starts points to an intermittent fault
3Check that the connectors at the fuel pump are tight and free from oxidation
4Use a multimeter to check that the cable between the heater connector and the pump connector is intact; a break means the cable must be replaced
5If the fault returns, have a workshop check the fuel pump and the wiring

Symptome, die Sie bemerken können2

Poor heating in the passenger compartment
The parking heater does not work

Was der Fehler beeinflussen kann1
