Hva betyr feilkoden?
The CEM communicates with the overhead console (OHC) and the rear reading light (RRL) over the LIN bus. The fault is stored when communication with the overhead console is missing, and the fault affects the passenger compartment lighting and the electric sunshade.
Mulige årsaker
- Open circuit in the communication wire to the overhead console
- Contact resistance, oxidation or poor contact in the connector terminals and connections
- The overhead console is not receiving power
- Damaged overhead console (OHC)
Hva du kan gjøre
- 1Check that the fuses are intact and that the overhead console receives power
- 2Check the connectors at the overhead console: loose or oxidised connectors should be cleaned and pressed in
- 3Check the communication wire to the overhead console for breaks and chafing
- 4Use a multimeter to check that voltage is present at the overhead console connector with the ignition on
- 5If the fault remains, have a workshop check or replace the overhead console
