Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-B1C8214

Condition
The central electronic module (CEM) supplies voltage to the headlights' motor for high-pressure washing.
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:
- 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.
- Short-circuit to ground.

Fault symptom[s]
- Headlight washer pump does not work
- Washer pump not possible to turn off
