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

- 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

NOTE: This test shows text for a Left Hand Drive (LHD) vehicle. Right Hand Drive (RHD) vehicles use the same cavities. Refer to the schematic for difference names and circuit numbers.

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 B1861-PASSENGER WINDOW MOTOR CONTROL CIRCUIT OPEN?

Yes

- Go To 2

No

- The conditions that caused this code to set are 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 MOTOR OR CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Passenger Express Window Motor connector.
3. Connect a test light between the (Q312) Right Front Window Express Up Driver circuit and the (Q322) Right Front Window Express Down Driver 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 (regulator).
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. (Q322) RIGHT FRONT WINDOW EXPRESS DOWN DRIVER CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Passenger Door Module C4 connector.
3. Measure the resistance of the (Q322) Right Front Window Express Down Driver circuit between the C4 module connector and the motor connector.

Is the resistance below 2.0 ohms?

No

- Repair the (Q322) Right Front Window Express Down Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Go To 4

4. (Q312) RIGHT FRONT WINDOW EXPRESS UP DRIVER CIRCUIT OPEN




1. Measure the resistance of the (Q312) Right Front Window Express Up Driver circuit between the C4 module connector and the motor connector.

Is the resistance below 2.0 ohms?

No

- Repair the (Q312) Right Front Window Express Up Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Replace the Passenger Door Module.
