REAR WIPER MOTOR CIRCUIT

REAR WIPER MOTOR CIRCUIT

Diagnosis Procedure

INFOID:0000000010431003

1.

CHECK REAR WIPER MOTOR OUTPUT VOLTAGE

1.

Turn rear wiper switch OFF, and wait for 1 minute or more. 

2.

Turn ignition switch OFF.

3.

Disconnect rear wiper motor connector.

4.

Turn ignition switch ON.

5.

With operating rear wiper switch, check voltage between rear wiper motor harness connector and ground.

*: When rear wiper motor connector is disconnected and rear wiper switch is ON for more than 5 seconds,
BCM stops the power supply according to rear wiper motor protection function. To perform the check again,
turn rear wiper switch OFF, wait for 1 minute or more, and then perform the check.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

CHECK REAR WIPER MOTOR CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect BCM connector.

3.

Check continuity between BCM harness connector and rear wiper motor harness connector.

4.

Check continuity between BCM harness connector and ground.

Is the inspection result normal?

YES

>> Replace BCM. Refer to 

BCS-132, "Removal and Installation"

.

NO

>> Repair or replace harness.

3.

CHECK REAR WIPER MOTOR GROUND OPEN CIRCUIT

Check continuity between rear wiper motor harness connector and ground.

Is the inspection result normal?

YES

>> Replace rear wiper motor.

NO

>> Repair or replace harness.
