Co oznacza ten kod błędu?
The right camera module (RCM) communicates with the CEM over the LIN bus. The fault is stored when communication with the camera module is missing for too long with the engine running. The cause is an open or short circuit in the wire between the camera module and the CEM.
Możliwe przyczyny
- Open circuit or short circuit in the wire for communication with the CEM
Co możesz zrobić
- 1Check that the fuses are intact
- 2With the engine running, check whether the blind spot system on the right side works, then clear the fault code and road test
- 3Check the communication wire between the right camera module and the CEM for breaks, chafing and pinch damage
- 4Check the connectors in the camera module wire: loose or oxidised connectors should be cleaned and pressed in
- 5Use a multimeter to check that the wire is continuous between the connector ends and is not short-circuited to earth or voltage
Objawy, które możesz zauważyć2
- A text message appears in the display
- The blind spot monitoring system (BLIS) does not work
