B185E-13

B185E-13-PASSENGER WINDOW CONTROL - CIRCUIT OPEN





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 module is awake.

- Set Condition:
When one or both Passenger Window Driver circuits (Up and Down) are not supplied with voltage, when they should be, during a window movement command for more than five ms., this code will set.





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

Does the scan tool display; B185E-13-PASSENGER WINDOW CONTROL - CIRCUIT OPEN?

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 OR CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Passenger Window Motor harness connector.
3. Connect a test light between the (Q12) Passenger Window Driver Up circuit and the (Q22) Passenger Window Driver Down circuit.
4. Turn the ignition on.
5. Operate the passenger window switch up and down several times while observing the test light.

Does the test light illuminate brightly when the switch is pressed in both directions? With the express up window, the test light will only flash momentarily each time the switch is actuated.

Yes

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

No

- Go To 3

3. (Q22) PASSENGER WINDOW DRIVER DOWN CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Passenger Door Module C4 harness connector.
3. Measure the resistance of the (Q22) Passenger Window Driver Down circuit between the C4 module connector and the motor connector.

Is the resistance below 2.0 Ohms?

No

- Repair the open in the (Q22) Passenger Window Driver Down circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Go To 4

4. (Q12) PASSENGER WINDOW DRIVER UP CIRCUIT OPEN




1. Measure the resistance of the (Q12) Passenger Window Driver Up circuit between the C4 module connector and the motor connector.

Is the resistance below 2.0 Ohms?

No

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

Yes

- Replace the Passenger Door Module. Door Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
