Hva betyr feilkoden?
The central electronic module (CEM) powers the left low beam directly through an output. The code is set when the signal wire to the low beam lamp is shorted to ground, and The fault can therefore show both when you switch the low beam on and in a later drive.
Mulige årsaker
- The signal wire to the low beam lamp is shorted to ground
Hva du kan gjøre
- 1Clear the code and check whether it comes back after a new driving cycle with the low beam on
- 2Check that the fuse for the left low beam is intact
- 3Look for chafing on the signal wire to the left low beam lamp, especially where it may have touched metal
- 4Use a multimeter to check that the signal wire has no contact with ground (the bodywork)
- 5If the wire is intact, have a workshop with diagnostic equipment check the module output and the lamp
Symptomer du kan merke3
- The headlight does not work
- Yellow warning symbol and text message in the display
- The bulb failure warning in the instruments comes on or behaves abnormally
Hva feilen kan påvirke3
- The function switches off during the driving cycle in which the fault is detected
- After repeated driving cycles with the fault, the function is switched off permanently
- Clearing the fault codes and starting a new driving cycle resets the output
