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
.
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.
