What does this fault code mean?
The front display receives the information it needs from the central electronic module (CEM) over CAN communication. The fault code is set when communication with the CEM is lost. Fault tracing therefore starts in the CEM, since it is the control module that sends the information.
Possible causes
- Fault in the transmitting control module, here the central electronic module (CEM)
