Hva betyr feilkoden?
The twilight sensor gives the CEM information about the light conditions, and the CEM uses it to set the brightness of the symbols and the instrument lighting. The code is stored when the sensor itself reports an internal fault, and then the instrument and button lighting does not work as it should.
Mulige årsaker
- Internal short circuit in the twilight sensor
Hva du kan gjøre
- 1Note the code, clear it and check whether it returns after a drive
- 2If you have a diagnostic tool: read the twilight sensor value in live data and check whether it changes when the light changes
- 3Check that the relevant fuses are intact. Their locations are in the owner's manual or on the fuse box cover
- 4If the fault remains, have a workshop with diagnostic equipment replace the twilight sensor
