Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information
Condition
The Driver door module (DDM) supplies voltage to the lock motor, blocked lock position. Power supply, folding of door mirror and power supply, motor blocked lock position split cable inside control module. Therefore, this DTC is always generated in pairs with corresponding DTC for power supply for door mirror folding.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The current strength is too low on the output when activating/deactivating the blocked lock position.
- The current strength is too low on the output when activating the central locking.
- The current strength on the output is too high when NO locking command is given.
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
- The cable for voltage feed is short-circuited to voltage.
- Open-circuit in the power supply cable.
- 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, folding of door mirror has short-circuit to ground.
- Power supply, common lock motor has short-circuit to voltage or open-circuit.
- Power supply, folding of door mirror has short-circuit to voltage or open-circuit.
Fault symptom[s]
- Locking/unlocking/Central locking does not work
- Door mirrors/Folding does not work
- Door mirrors/Folding does not work
