Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
If for some reason the door window regulator loses information on the window's position, a diagnostic trouble code is generated and that power window is no longer operational.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Initiation of the left front door window is lost.
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
- None.

Possible source
- Initialization has not been carried out.
- The window position settings have been lost by the control module. This is due to a voltage drop when the window lift mechanism was activated.
- Power supply to the control module has been cut off.

Fault symptom[s]
- The automatic window operation does not work
