Hva betyr feilkoden?
The central electronic module (CEM) supplies power to the interior lighting. The fault code is stored when the module detects an incorrect signal on the lighting output. The cause is a short circuit to ground in the power supply cable to the lighting.
Mulige årsaker
- Short circuit to ground in the cable that supplies the interior lighting
Hva du kan gjøre
- 1Check that the lamp is not faulty and that its connector is secure
- 2With the ignition off, check the cable to the lighting for chafing, pinching and loose connections
- 3With the ignition off, use a multimeter to check whether the supply cable has contact with earth (the body); if it does, that is the short circuit
- 4Remedy the short circuit if it is found, reconnect the connectors and clear the fault code
- 5Switch the ignition on, open a door and check that the interior lighting comes on. If the fault remains, have a workshop with diagnostic equipment check the control module
Symptomer du kan merke1
- Interior lighting does not work
Hva feilen kan påvirke1
- If the fault remains over many ignition cycles, the output is switched off permanently until the fault code is cleared
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
