REAR WIPER MOTOR CIRCUIT

Component Function Check

INFOID:0000000009945842

1.

CHECK REAR WIPER ON OPERATION

CONSULT ACTIVE TEST

1.

Select “RR WIPER” of BCM active test item.

2.

With operating the test item, check rear wiper operation.

Is rear wiper operation normally?

YES

>> Rear wiper motor circuit is normal.

NO

>> Refer to 

WW-37, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009945843

1.

CHECK REAR WIPER MOTOR OUTPUT VOLTAGE

CONSULT ACTIVE TEST

1.

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

2.

Turn the ignition switch OFF.

3.

Disconnect rear wiper motor connector.

4.

Turn the ignition switch ON.

5.

Select “RR WIPER” of BCM active test item.

6.

With operating the test item, check voltage between rear wiper motor harness connector and ground.

*: When “REAR WIPER” is “On” for 5 seconds or more during active test of CONSULT, BCM stops the power
supply according to rear wiper motor protection function. To perform the check again, turn “REAR WIPER” to
“Off”, wait for 1 minute or more, and then perform the check.

Is the measurement value normal?

YES

>> GO TO 4.

NO

>> GO TO 2.

2.

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 3.

NO

>> Repair the harness or connector.

3.

CHECK REAR WIPER MOTOR SHORT CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect BCM connector.

On

: Rear wiper ON operation

Off

: Stop the rear wiper.

 (without Intelligent Key system).

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.

Component Function Check

INFOID:0000000009945844

1.

CHECK REAR WIPER STOP POSITION SIGNAL

CONSULT DATA MONITOR

1.

Select “WIPER” of BCM data monitor item.

2.

Operate the rear wiper.

3.

With the rear wiper operation, check the monitor status.

Is the status of item normal?

YES

>> Rear wiper stop position signal circuit is normal.

NO

>> Refer to 

WW-39, "Diagnosis Procedure"

.
