4D-PASSENGER WINDOW SWITCH SHORT TO GROUND





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams

- When Monitored:
Whenever the ignition is in the RUN or ACCESSORY position.

- Set Condition:
When the BCM senses that the voltage on the Passenger Window Switch Mux circuit is less than 0.69 volts for longer than 10 seconds.





1. DTC PRESENT
1. Turn the ignition on.
2. With the scan tool, erase the DTCs.
3. Cycle the ignition switch from Off to Run.
4. Operate the Passenger Window Motor.
5. With the scan tool, read the DTCs.

Does the scan tool display 4D-PASSENGER WINDOW SWITCH SHORT TO GROUND?

Yes

- Go To 2

No

- The condition that caused the code to set is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. WINDOW SWITCH




1. Disconnect the Window Switch connector.
2. Turn the ignition on.
3. Measure the voltage between the (Q3) Passenger Window Switch Mux circuit and ground.

Is the voltage approximately 5.0 volts?

Yes

- Replace the Window Switch.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. (Q3) PASSENGER WINDOW SWITCH MUX WIRE SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the BCM C3 harness connector.
3. Measure the resistance between ground and the (Q3) Passenger Window Switch Mux circuit in the window switch connector.

Is the resistance below 10,000 ohms?

Yes

- Repair the (Q3) Passenger Window Switch Mux circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Body Control Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
