REAR WIPER AUTO STOP SIGNAL CIRCUIT

Component Function Check

INFOID:0000000009484707

1.

 CHECK REAR WIPER (AUTO STOP) OPERATION

CONSULT DATA MONITOR

1. Select "WIPER" of BCM data monitor item.

2. Operate the rear wiper.

3. Check that "RR WIPER STOP" changes to "ON" and "OFF" linked with the wiper operation.

Is the status of item normal?

YES

>> Rear wiper auto stop signal circuit is normal.

NO

>> Refer to 

WW-31, "Diagnosis Procedure"

.

1. Turn ignition switch OFF.

2. Disconnect BCM and rear wiper motor.

3. Check continuity between BCM harness connector terminals

and rear wiper motor harness connector terminals.

Is inspection result normal?

YES

>> GO TO 2

NO

>> Repair or replace harness.

2.

 CHECK AUTO STOP CIRCUITS FOR SHORT TO GROUND

Check continuity between BCM harness connector terminals and

ground.

Is inspection result normal?

YES
