Was bedeutet der Fehlercode?
The auxiliary heater relay is an electrical switch controlled by the CEM, and the fault code is only stored when the relay is activated. The module has then registered a short between the auxiliary heater and battery voltage. The fault is intermittent, so it may have occurred earlier without being active now, and it causes poor interior heating.
Mögliche Ursachen
- Auxiliary heater relay circuit short-circuited to voltage
Was Sie tun können
- 1Clear the code and road test with the auxiliary heater switched on to see whether the fault returns
- 2Check that the relay is firmly seated in its holder and is not damaged or corroded
- 3Check the auxiliary heater fuse and replace it if it has blown
- 4Use a multimeter to check that the relay wire has no contact with voltage supply
- 5Remedy what is found and check that the cabin heating improves
Symptome, die Sie bemerken können1
- Poor interior heating
