Faulty Signal
Faulty signal
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. Check for contact resistance and oxidation and remedy. 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 Window lift mechanism front side door, replacing Service and Repair
- Checking wiring and terminals Checking Wiring And Terminals.
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 #24A and power window motor terminal connector #2. Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an open-circuit.
Remedy as necessary.
Other information:
- When raising or lowering the window, the voltage between power window lift motor terminal #2 and ground must be 2.4 V
- To connect the breakout box, see Connecting the breakout box Connecting the Breakout Box
- For further information about signals and other values, see Signal specification Signal Specification, Driver Door Module (DDM) / Passenger Door Module (PDM)
- Checking wiring and terminals Checking Wiring And Terminals.
Was a fault detected?
Yes - Verification
No - Replacing the component
-------------------------------------------------
Replacing the component
Replace the power window mechanism according to Window lift mechanism front side door, replacing Service and Repair.
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
-------------------------------------------------
Verification
Verification
Hint: After the repair it is necessary to check that the fault has been rectified.
- Ignition off.
- Connect connectors, install components, etc.
- Ignition on.
Check that the automatic window operation works by pressing in the button 2 stages one way or the other.
Does the automatic window operation work?
Yes - Verification completed
No - Fault-tracing information
-------------------------------------------------
Fault-tracing information
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 - Exit Fault-Tracing
No - Attempt New Test
------------------------
Attempt New Test - Checking for permanent or intermittent faults
-------------------------------------------------
Fault-tracing information
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).
Do you want to view the information again?
Yes - Attempt New Test
No - Exit fault-tracing
------------------------
Attempt New Test - Checking for permanent or intermittent faults
-------------------------------------------------
Intermittent fault
Check the connectors for the control module and power window lift motor. Check for contact resistance and oxidation. Check for loose connections.
Check the cable between control module terminal #24A and power window motor terminal #2. Check for an intermittent short-circuit to ground. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.
