Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The Driver door module (DDM) supplies voltage to the central lock motor in the driver door.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The current strength is too low on the output when deactivating the central locking.
- The current strength is too low on the output when activating the central locking.
- The current strength on the output is too high when the central locking is NOT activated/deactivated.

Hint: Sometimes, the DTC may also be generated due to an error that initially must be detected/handled by another DTC/other DTCs.

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
- Function for folding and power adjustment of door mirrors blocked to prevent unintentional locking of the vehicle.

Possible source
- Open-circuit in the power supply cable.
- The voltage feed cable is short-circuited to voltage.
- Contact resistance, oxidation or poor contact in connections.

The DTC may also be generated for the following reasons, which are first detected/handled by another DTC/other DTCs:
- Power supply to common lock motor has an open-circuit or short-circuit to voltage.

Fault symptom[s]
- Locking/unlocking/Central locking does not work
- Door mirrors/Electrical adjustment does not work
- Door mirrors/Folding does not work
