Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-3F02

Condition




The central electronic module (CEM) checks the function of the shift lock.
The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers a short-circuit to battery voltage in the output signal for shift lock.
The relay for shift lock must be activated for the diagnostic trouble code (DTC) to be stored. The diagnostic trouble code (DTC) can be diagnosed in ignition positions I and II.

Substitute value
- If the fault has been detected in 100 ignition cycles, the output is closed permanently until the diagnostic trouble code is erased (applies from structure week 200539).

Possible source
- Short-circuit to the positive supply in the "inhibited shifting" output signal. The relay is not activated.

Fault symptom[s]
- The starter motor does not turn
- The engine does not start.
