Hva betyr feilkoden?
The central electronic module (CEM) controls the power to the auxiliary lights through a control signal. The fault code is stored when the auxiliary lights are powered although they should not be. The auxiliary lights then do not work.
Mulige årsaker
- Supply cable shorted to voltage
Hva du kan gjøre
- 1Check that the fuses for the auxiliary lights are intact
- 2Switch the ignition off, wait a moment and switch it on again to see whether the auxiliary lights work
- 3With the ignition off, check the cable to the auxiliary lights for chafing and pinching, especially where it may have touched a live wire
- 4With the ignition off, use a multimeter to check whether the supply cable has voltage; voltage when the ignition is off means a short to voltage
- 5Remedy the fault and clear the fault code. If it remains, have a workshop check the control module
