Hva betyr feilkoden?
The central electronic module (CEM) has registered that the signal returned from the blower fan is outside the expected range. This can be caused by a short to voltage or a break in the circuit to the fan. The fault is checked by running the fan.
Mulige årsaker
- Fan short-circuited to voltage supply
- Open circuit in the fan circuit
Hva du kan gjøre
- 1Read and clear the code, run the fan and check whether it starts and runs
- 2Check that the fan wheel turns freely with nothing blocking it
- 3Check that the fan connector is secure and free from corrosion
- 4Use a multimeter to check that the wire between the control module and the fan is not broken and has no contact with voltage supply
- 5If no fault is found in the wiring, the fan is the likely cause and a workshop should replace it
Symptomer du kan merke1
