Hva betyr feilkoden?
The central electronic module (CEM) supplies the interior lighting in the passenger compartment through circuit A. The code is set when the signal from the output is too low, which can be caused by the supply wire being shorted to ground or having an open circuit.
Mulige årsaker
- The supply wire to the interior lighting is shorted to ground
- Open circuit in the supply wire to the interior lighting
Hva du kan gjøre
- 1Read and clear the code, then switch on the interior lighting and see whether it works
- 2Check that the fuses for the interior lighting are intact
- 3Look for breaks and chafing on the supply wire, especially where the wiring harness is fixed
- 4Use a multimeter to check that the supply wire has no contact with ground (the bodywork) and is intact
- 5If the wire is intact, have a workshop with diagnostic equipment check the module output
