Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-8F1D

Condition




The central electronic module (CEM) checks the voltage on the driver circuits for the 15-supply and headlamp range adjustment. This is achieved by a common re-activation of the drive circuit.
The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers from the re-engagement signal that there is a short-circuit to supply voltage in the output from one of the drive circuits.
The diagnostic trouble code (DTC) can be detected at ignition position 0 and I.

Substitute value
- None.

Possible source
- Short-circuit to supply voltage in the signal cable.

Fault symptom[s]
- Beam height control does not function.
- Automatic headlamp range control is not functioning.
- Incorrect setting for low beam.
