Hva betyr feilkoden?
The central electronic module (CEM) supplies the interior lighting. The code is set when the signal from the output is too low, which can be caused by a short to ground or an open circuit in the supply wire.
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 fuse for the interior lighting is intact
- 3Look for loose, corroded or broken connectors in the supply wire
- 4Use a multimeter to check that the supply wire has no contact with ground (the bodywork)
- 5If the wiring is complete, have a workshop with diagnostic equipment check the module output
Symptomer du kan merke1
