Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B113087

Condition
The Central Electronic Module (CEM) both transmits and receives information via a standardized serial communication method - LIN (Local Interconnect Network).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- If the control module registers a serious malfunction, e.g., that LIN-communication to Light switch module (LSM) is blocked, the diagnostic trouble code is generated.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position I and II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- None.

Possible source
- Short-circuit between the LIN wiring.
- Open-circuit in the LIN wiring.
- Internal fault in another unit in the same part of the LIN network.

Fault symptom[s]
- Beam adjustment control not working
