B185E-12

B185E-12-PASSENGER WINDOW CONTROL - CIRCUIT SHORT TO BATTERY





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

Theory of Operation

If either one of the Window Driver circuits are shorted to battery, the motor will operative in one direction only. If the current remains on when the window is in its full travel, the circuit breaker will open. 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 both Passenger Window Driver circuits (Up and Down) are supplied with voltage 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-12-PASSENGER WINDOW CONTROL - CIRCUIT SHORT TO BATTERY?

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 harness connector.
4. Turn the ignition on.
5. Operate the Passenger window switch up and down several times.
6. With the scan tool, read the DTCs.

Does the scan tool display; B185E-12-PASSENGER WINDOW CONTROL - CIRCUIT SHORT TO BATTERY?

Yes

- Go To 3

No

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

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




1. Turn the ignition off.
2. Disconnect the Passenger Door Module C4 harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (Q22) Passenger Window Driver Down circuit.

Is there any voltage present?

Yes

- Repair the (Q22) Passenger Window Driver Down circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

4. (Q12) PASSENGER WINDOW DRIVER UP CIRCUIT SHORTED TO VOLTAGE




1. Measure the voltage between the (Q12) Passenger Window Driver Up circuit and Ground.

Is there any voltage present?

Yes

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

No

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