Was bedeutet der Fehlercode?
On vehicles with dimmed daytime running lights, each light is fed from the CEM through two outputs. The fault shows that the voltage on the wire to the dimmed daytime running light is too high, which can be caused by a short to battery voltage or a break in the supply. The fault is checked when the parking lights are not switched on.
Mögliche Ursachen
- The supply is shorted to battery voltage
- Break in the supply wire
