Diagnosis Procedure


1. CHECK REAR WIPER MOTOR OUTPUT VOLTAGE

CONSULT ACTIVE TEST
1.Turn the ignition switch OFF.
2.Disconnect rear wiper motor connector.
3.Turn the ignition switch ON.
4.Select "RR WIPER" of BCM active test item.
5.With operating the test item, check voltage between BCM harness connector and ground.





Is the measurement value normal?
YES- GO TO 3.
NO- GO TO 2.

2. CHECK REAR WIPER MOTOR SHORT CIRCUIT

1.Turn the ignition switch OFF.
2.Disconnect BCM connector.
3.Check continuity between BCM harness connector and ground.





Does continuity exist?
YES- Repair the harness or connector.
NO- Replace BCM. Refer to "Exploded View" Exploded View.

3. CHECK REAR WIPER MOTOR OPEN CIRCUIT

1.Turn the ignition switch OFF.
2.Disconnect BCM connector.
3.Check continuity between BCM harness connector and rear wiper motor harness connector.





Does continuity exist?
YES- GO TO 4.
NO- Repair the harness or connector.

4. CHECK REAR WIPER MOTOR GROUND OPEN CIRCUIT

Check continuity between rear wiper motor harness connector and ground.





Does continuity exist?
YES- Replace rear wiper motor.
NO- Repair the harness or connector.
