CEM-E001

Diagnostic trouble code (DTC) information CEM-E001

Condition




The control modules transmit and receive information via a standardized serial communication method - CAN (Control Area Network). The diagnostic trouble code (DTC) is stored if the control module registers serious interference on the low speed network (CAN communication blocked).

Substitute value
- The control module shuts itself off ("bus-off").

Hint: The control module will remain shut off until the power supply is broken (15, 30, X). When the power supply is connected the control module will make a new attempt to communicate.

Possible source
- Short-circuit between the control area network (CAN) wiring
- Open-circuit in one of the control area network (CAN) cables
- Internal fault in the control module
- Internal fault in another control module in the same part of the control area network (CAN).

Fault symptom[s]
- No gauges are working
- The instrument lighting does not operate
- Cannot be controlled with the remote control.
