5. Does the rear wiper operate normally? If YES: GO TO 6. If NO: GO TO 4.
6. Inspection End.
Preliminary InspectionEKS00BEG
INSPECTION FOR POWER SUPPLY AND GROUND CIRCUIT
Inspection procedure
1. CHECK FUSE
Check if wiper or washer fuse is blown.
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of problem before installing new fuse. Refer to PG-4,
"POWER SUPPLY ROUTING CIRCUIT" .

2. CHECK POWER SUPPLY CIRCUIT
1. Disconnect BCM connectors.
2. Check voltage between BCM harness connector terminals and
ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open or short between BCM and fuse.
3. GROUND CIRCUIT INSPECTION (BCM)
Check for continuity between the BCM terminal and ground.
OK or NG

3. CHECK REAR WIPER MOTOR AUTO STOP SWITCH GROUNDS
Check continuity between rear wiper motor harness connector D704
terminals and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4. CHECK REAR WIPER OPERATING
1. Connect BCM connectors and rear wiper motor connector.
2. Turn ignition switch ON.
3. Turn rear wiper switch ON, then to OFF when wiper arm
reaches mid sweep.
4. Check voltage between rear wiper motor connector D704 termi-
nal 6 (Y) and ground.
OK or NG
OK >> Replace rear wiper motor. Refer to WW-53, "Removal
and Installation of Rear Wiper Motor" .
NG >> Replace BCM. Refer to BCS-20, "
Removal and Installation of BCM" .
Only Rear Wiper Does Not OperateEKS00BEK
1. CHECK COMBINATION SWITCH INPUT SIGNAL
Select "BCM" on CONSULT-II. With "WIPER" data monitor, make
sure "RR WIPER ON" turns ON-OFF according to operation of wiper
switch.
OK or NG
OK >> Replace BCM. Refer to BCS-20, "Removal and Installa-
tion of BCM" .
NG >> Check the wiper switch. Refer to WW-7, "
