B185E-11

B185E-11-PASSENGER WINDOW CONTROL - CIRCUIT SHORT TO GROUND





For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

If either one of the Window Driver circuits are open, the motor will be totally inoperative. To lower the window, voltage is applied to the (Q22) Window Driver (Down) circuit and the (Q12) Window Driver (UP) circuit remains grounded in the module. To drive the window up, the circuits are reversed.

- When Monitored:
Whenever the window motor is operating.

- Set Condition:
When both Passenger Window Driver circuits (Up and Down) are grounded during a window movement command, this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Try to operate the Passenger Window up and down several times.
4. Wait 30 seconds.
5. With the scan tool, read DTCs.

Does the scan tool display; B185E-11-PASSENGER WINDOW CONTROL - CIRCUIT SHORT TO GROUND?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. WINDOW MOTOR SHORTED




1. With the scan tool, erase the DTCs.
2. Turn the ignition off.
3. Disconnect the Passenger Window Motor connector.
4. Turn the ignition on.
5. Operate the passenger window switch up and down several times.
6. With the scan tool, read the active DTCs.

Does the scan tool display; B185E-11-PASSENGER WINDOW CONTROL - CIRCUIT SHORT TO GROUND?

Yes

- Go To 3

No

- Replace the Window Motor. Window Regulator Motor - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

3. (Q22) PASSENGER WINDOW DRIVER DOWN CIRCUIT SHORTED TO GROUND




1. Turn the ignition off.

Yes

- Repair the short to ground in the (Q12) Passenger Window Driver Up circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 5

5. (Q22) PASSENGER WINDOW DRIVER DOWN CIRCUIT SHORTED TO (Q12) PASSENGER WINDOW DRIVER UP CIRCUIT




1. Measure the resistance between the (Q22) Passenger Window Driver Down circuit and the (Q12) Passenger Window Driver Up circuit.

Is the resistance below 10k Ohms?

Yes

- Repair the short between the (Q22) Passenger Window Driver Down circuit and the (Q12) Passenger Window Driver Up circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Passenger Door Module. Door Module - Removal.
