What does this fault code mean?
The left camera module (LCM) communicates with the CEM over the LIN bus. The fault is stored when components inside the camera module itself are not working, and The fault is therefore in the camera module and not in the wiring.
Possible causes
- Internal fault in the left camera module (LCM)
What you can do
- 1Check that the connectors to the left camera module are secure and not corroded
- 2Start the engine and check whether the blind spot system works, then clear the fault code and road test
- 3If the code returns after the road test the fault is permanent; if it does not return the fault may have been intermittent
- 4The camera module is not sold as a spare part, so for a permanent fault the whole outside mirror must be replaced, which is a job for a workshop
Symptoms you may notice2
- A text message appears in the display
- The blind spot monitoring system (BLIS) does not work
