Hva betyr feilkoden?
The central electronic module (CEM) supplies the auxiliary lights. The code is set when the output signal is too high, which is caused by the supply wire being shorted to voltage.
Mulige årsaker
- The supply wire to the auxiliary lights is shorted to voltage
Hva du kan gjøre
- 1Read and clear the code, then switch on the auxiliary lights and see whether they work
- 2Check that the fuse for the auxiliary lights is intact
- 3Look for chafing on the supply wire to the auxiliary lights, especially where the cable may have been pinched
- 4Use a multimeter to see whether the supply wire has voltage with the ignition off
- 5If you have a diagnostic tool, activate the auxiliary lights with it and see whether they come on; otherwise have a workshop check the relay
Symptomer du kan merke1
- The auxiliary lights do not work
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
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
