Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The Driver door module (DDM) powers the heating loop for defrosting the door mirror.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The current strength is too high on the output.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Control module supplied with power.
- Activation of defroster.

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
- None.

Possible source
- Short-circuit to ground in the signal cable for the defroster in the door mirror.
- Moisture and/or oxidation in terminals.
