Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B10F515

Condition
The Central electronic module (CEM) powers the rear left-hand parking lamps directly via an output.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Signal too high from the output.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Activated 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
- Contact resistance, oxidation or poor contact in connections.
- Open circuit on signal cable.
- Short-circuit to supply voltage in the signal cable.

Fault symptom[s]
- Tail light/Does not work
