B1853-11

B1853-11-DRIVER 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 (Q21) Window Driver (Down) circuit and the (Q11) 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 both Driver 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 the DTCs.
3. Try to operate the Driver Window up and down several times.
4. Wait 30 seconds.
5. With the scan tool, read the active DTCs.

Does the scan tool display: B1853-11-DRIVER 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 poor pin fit.
- 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 Driver Window Motor connector.
4. Turn the ignition on.
5. Operate the driver window switch up and down several times.
6. With the scan tool, read the active DTCs.

Does the scan tool display: B1853-11-DRIVER WINDOW CONTROL - CIRCUIT SHORT TO GROUND?

Yes

- Go To 3

No

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

3. (Q21) DRIVER WINDOW DRIVER (DOWN) CIRCUIT SHORTED TO GROUND




1. Turn the ignition off.
2. Disconnect the Driver Door Module C4 connector.
3. Measure the resistance between Ground and the (Q21) Driver Window Driver Down circuit.

Is the resistance below 10,000 Ohms?

Yes

- Repair the (Q21) Driver Window Driver Down circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. (Q11) DRIVER WINDOW DRIVER (UP) CIRCUIT SHORTED TO GROUND




1. Measure the resistance between Ground and the (Q11) Driver Window Driver Up circuit.

Is the resistance below 10,000 Ohms?

Yes

- Repair the (Q11) Driver Window Driver (Up) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 5

5. (Q21) DRIVER WINDOW DRIVER (DOWN) CIRCUIT SHORT TO THE (Q11) DRIVER WINDOW DRIVER (UP) CIRCUIT




1. Measure the resistance between the (Q21) Driver Window Driver (Down) circuit and the (Q11) Driver Window Driver (Up) circuit.

Is the resistance below 10,000 Ohms?

Yes

- Repair the (Q21) Driver Window Driver (Down) circuit for a short to the (Q11) Driver Window Driver (Up) circuit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

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