Diagnostic Trouble Code (DTC) Information CEM-2F61
Condition
The central electronic module (CEM) receives information about the prevailing light conditions from the twilight sensor.
This information is used to determine the light intensity for symbols and the instrument lighting. Two different levels are pre-defined, one for day and one for night.
The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers a short-circuit to ground in the twilight sensor circuit.
The diagnostic trouble code (DTC) can be diagnosed at key positions I and II.
Substitute Value
- The light intensity for night is used.
Possible Source
- Short-circuit to ground in the signal cable
- The twilight sensor does not operate.
Fault symptom[s]
- The lighting in the instrument panel does not function.
