Co oznacza ten kod błędu?
The CEM supplies the right rear fog lamp directly from an output and monitors the voltage. The fault is stored when the signal from the output is too low, and the cause is either a supply wire short-circuited to earth, poor contact, or a signal wire short-circuited to earth. The fault is checked with the fog lamp switched on.
Możliwe przyczyny
- The supply wire is short-circuited to earth
- Contact resistance, oxidation or poor contact in the connections
- The signal wire is short-circuited to earth
Co możesz zrobić
- 1Check that the fuses for the fog lamps are intact
- 2Switch on the fog lamps and see whether the right rear lamp lights, then clear the fault code and road test
- 3Check the connectors at the lamp and at the CEM, and the wiring for chafing: loose or oxidised connectors should be cleaned and pressed in
- 4Use a multimeter to check that the wire has no contact with earth (the body) with the connectors disconnected
- 5If the fault returns, have a workshop with diagnostic equipment fault-trace the control module and the wiring
Objawy, które możesz zauważyć2
- The right rear fog lamp does not light
- Yellow warning symbol and text message in the display
Na co może wpływać usterka3
- The output switches off during the driving cycle in which the fault is detected
- If the fault remains, the output is switched off permanently after 100 driving cycles where the fault was detected
- Erasing the fault codes and starting a new driving cycle resets the output
