>> Rear wiper motor circuit is normal.

NO

>> Refer to

WW-43, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009578888

Regarding Wiring Diagram information, refer to

WW-25, "Wiring Diagram"

.

1.

CHECK REAR WIPER MOTOR OUTPUT VOLTAGE

CONSULT ACTIVE TEST

1. Turn the ignition switch OFF.

2. Disconnect rear wiper motor.

3. Turn the ignition switch ON.

4. Select "RR WIPER" of BCM active test item.

5. While operating the test item, check voltage between BCM harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 2

NO

>> GO TO 3

2.

CHECK REAR WIPER MOTOR GROUND CIRCUIT

1. Turn the ignition switch OFF.

2. Check continuity between rear wiper motor harness connector and ground.

Does continuity exist?

YES

>> Replace rear wiper motor. Refer to

WW-67, "Removal and Installation"

.

NO
