Co oznacza ten kod błędu?
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.
Możliwe przyczyny

- Open circuit in the supply wire to the interior lighting
Co możesz zrobić
- 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
