Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The control module in the relevant rear door powers the window lift via a relay. The control module left rear door/right rear door (LDM/RDM) supplies the control module driver's door/passenger door (DDM/PDM) with information about status of the relay.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The relay for window motor up is active even though it should be inactive.
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
- The control module activates the relay for window lift down.

Possible source
- Relay has stuck in the active position.

Fault symptom[s]
- Electrical operated window/No/reduced/incorrect function
