Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-6C20

Condition




The child-proof lock function disengages the rear inner door handles and deactivates the power windows in the rear doors. The function can be activated from the switch panel on the driver's door. An extra motor has been installed in the rear doors to disengage the inner door handles. The central electronic module (CEM) receives an indication of the status of the lock motors (locked/unlocked).
If the lock motor for the child-proof lock in the right-hand rear door could not lock at the first attempt, the central electronic module (CEM) transmits an additional lock command. The diagnostic trouble code (DTC) is stored if the lock motor is not in the locked position after this attempt.

Substitute value
- None.

Possible source
- The lock motor has stuck in the unlocked position
- The lock motor has become too hot
- Defective switch for indication of the lock motor status.

Fault symptom[s]
- The child-proof lock does not function.
