Hva betyr feilkoden?
The central electronic module (CEM) feeds the right high beam from its own output. The code is set when the signal from the output is too low, which is caused by the signal cable being shorted to ground.
Mulige årsaker
- The signal cable to the right high beam is shorted to ground
Hva du kan gjøre
- 1Read and clear the code and switch on the high beam to see whether the lamps light
- 2Check that the fuse for the high beam is intact
- 3Inspect the signal cable to the right high beam lamp for chafing and marks from heat
- 4Use a multimeter to check that the signal cable has no contact with ground (the bodywork)
- 5If the wire is intact, have a workshop with diagnostic equipment check the module output
Symptomer du kan merke2
- The right high beam does not work
- Yellow warning symbol and text message in the display
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
