Hva betyr feilkoden?
The CEM communicates with the rear reading light (RRL) over the LIN bus. The fault is stored when the message from the reading light is faulty, so that its checksum does not match. The fault affects the lighting in the passenger compartment.
Mulige årsaker
- Contact resistance, oxidation or poor contact in the connector terminals and connections
- Damaged rear reading light (RRL)
Hva du kan gjøre
- 1Check that the rear reading light receives power and has a good earth point
- 2Check the connectors at the reading light and the wire on the LIN bus for chafing and loose connections
- 3If other fault codes in the same control module on the same LIN bus end in 86 or 88, give them priority, as they point to a bus fault
- 4If the fault remains after these checks, have a workshop replace the rear reading light
Symptomer du kan merke1
- The lighting in the passenger compartment does not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
