Hva betyr feilkoden?
The Central Electronic Module (CEM) monitors the voltage to the right front fog lamp. When the output gives too low a voltage while the fog lamp is switched on, the fault is stored. The cause is either increased contact resistance in the connections or a signal wire that is short-circuited to earth.
Mulige årsaker
- Increased contact resistance, oxidation or poor contact in the connections to the right fog lamp
- The signal wire to the right fog lamp is short-circuited to earth
Hva du kan gjøre
- 1Check that the fuses are intact
- 2Switch on the fog lamps and check whether the right lamp lights, then clear the code and road test
- 3Inspect the connectors at the lamp and at the control module, and clean or press in any that are loose or oxidised
- 4Use a multimeter to check that the signal wire has no contact with earth (the body) with the connectors disconnected
- 5If the fault returns despite these checks, have a workshop with diagnostic equipment check the control module and the wiring
Symptomer du kan merke1
- Right front fog lamp does not light
Hva feilen kan påvirke3
- The output switches off during the driving cycle in which the fault is detected
- It is switched off permanently after 100 driving cycles if the fault remains
- A new driving cycle or erasing the fault codes resets the output
