Checking for permanent or intermittent faults
- Ignition on.
Press the power window switch 2 steps up to check the function of the automatic power window mechanism.
Is the automatic power window mechanism functioning?
Yes - Intermittent fault
No - Checking the connectors
-------------------------------------------------
Checking the connectors
- Ignition off
- Check the power window lift motor connector for contact resistance and oxidation and remedy according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. In particular, check for any damage
- Reinstall the components, reconnect the connectors etc.
- Ignition on.
Press the power window switch 2 steps up and down.
Other information:
- To access the window lift mechanism, see appropriate service procedure.
Is the automatic power window mechanism functioning?
Yes - Fault Found
No - Checking for open-circuits and short-circuits
-------------------------------------------------
Checking for open-circuits and short-circuits
Check the cable between door control module terminal #23A and power window motor terminal #2. Check for a short-circuit to ground. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. Check for a short-circuit to supply voltage. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault. Check for an open-circuit. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Remedy as necessary.

Was a fault detected?
Yes - Verification
No - Replacing the component
-------------------------------------------------
Replacing the component
Replace the power window mechanism .
Ignition on.
Move the window to its upper limit position using manual control.
Initialize the window.
From model year 2003 inclusive, the window will lower approximately 10 centimeters and then close again during initialization.
Continue - Verification

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off.
- Reinstall the connectors, components etc.
- Ignition on.
Check that the automatic power window mechanism is functioning by pressing the 2 stage button in each direction.

Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - FAULT-TRACING FAILED
No - Attempt New Test

Information
Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
