Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information CEM-B112F11
Condition
The central electronic module (CEM) supplies voltage to the emergency brake light directly via an output.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Short-circuit to ground in the power supply cable.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Activated stop lamp.
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
- Short-circuit to ground in the power supply cable.
Fault symptom[s]
- Tail light/Brake light does not work
