Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B111513

Condition
The central electronic module (CEM) supplies voltage to the high-positioned brake light directly via an output.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Open-circuit in the power supply cable.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Control module supplied with power.

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
- The function switches off permanently after 100 operating cycles where the fault was detected. Erasing diagnostic trouble codes (DTCs) resets the result.

Possible source
- Open-circuit in the power supply cable.

Fault symptom[s]
- Tail light/Brake light does not work
