Signal Too Low Or Signal Missing
Signal too low or signal missing
Checking for permanent or intermittent faults
- Ignition on.
Press the switch for the power window to check the function of the power window mechanism.
Is the power window control operating correctly?
Yes - Intermittent fault
No - Checking the connectors
-------------------------------------------------
Checking the connectors
- Ignition off.
Check that the fuses are intact.
Check the control module and power window lift motor connectors. Check for contact resistance and oxidation.

- Checking wiring and terminals Checking Wiring And Terminals
Continue - Checking the cable
-------------------------------------------------
Checking the cable
Check the cable between control module connector terminal #B4 and power window lift motor connector terminal #3. Check for an open-circuit. Check for a short-circuit to ground.
Check the cable between control module connector terminal #B3 and power window lift motor connector terminal #6. Check for an open-circuit. Check for a short-circuit to ground.
Remedy as necessary.

Was the cable OK?
Yes - Replacing the component
No - Verification
-------------------------------------------------
Replacing the component
Replace the window lift mechanism.
- Ignition on.
Move the window to its upper limit position using manual control.
Initialize the window.
During initialization, the window will automatically go down to its lowest position and then go back up again.

Hint: After the repair it is necessary to check that the fault has been rectified.
- Ignition off.
- Connect the connectors, install the components, etc.
- Ignition on.
Check that window operates by raising/lowering window to its end stops.
Does window operate?
Yes - VERIFIED
No - VERIFICATION FAILED

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 connector terminal #B4 and power window lift motor connector terminal #3. Check for an intermittent open-circuit.
Check the cable between the control module connector terminal #3B and the power window lift motor connector terminal #6. Check for an intermittent open-circuit.

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?
