Front Wiper Does Not Return to Stop PositionAKS0079X
1. CHECK CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (1)
With CONSULT-ll
Select “IPDM E/R” on CONSULT-II. With data monitor, confirm that
“WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper oper-
ation.
Without CONSULT-ll
GO TO 2.
OK or NG
OK >> Replace IPDM E/R.
NG >> GO TO 2.
2. CHECK CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (2)
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connec-
tor.
3. Check continuity between IPDM E/R harness connector E7 ter-
minal 32 (L) and front wiper motor harness connector E57 termi-
nal 5 (L).
4. Check continuity between IPDM E/R harness connector E7 ter-
minal 32 (L) and Ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK IPDM E/R
1. Connect IPDM E/R connector and front wiper motor connector.
2. Turn ignition switch ON.
3. Check voltage between IPDM E/R harness connector terminal
and ground while front wiper motor is stopped and while it is
operating.
OK or NG
OK >> Replace IPDM E/R.
NG >> Replace front wiper motor.

How to Proceed With Trouble DiagnosisAKS0057L
1. Confirm the symptoms and customer complaint.
2. Understand operation description and function description. Refer to WW-35, "
System Description" .
3. Perform the Preliminary Check. Refer to WW-40, "
Preliminary Check" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the rear wiper and washer operate normally? If YES: GO TO 6. If NO: GO TO 4.

Preliminary CheckAKS0057M
INSPECTION POWER SUPPLY AND GROUND CIRCUIT
Inspection Procedure
1. CHECK FUSE

Check if wiper and washer fusible link and fuse is blown.
Refer to WW-37, "Wiring Diagram — WIP/ R —" .
OK or NG
OK >> GO TO 2.
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link. Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .

3. CHECK CIRCUIT BETWEEN BCM AND REAR WIPER
1. Turn ignition switch OFF.
2. Disconnect BCM connector and rear wiper motor connector.
3. Check continuity between BCM harness connector B14 termi-
nals 59 (Y), 70 (SB) and rear wiper motor harness connector
D107 terminals 3 (BR), 4 (SB).
4. Check continuity between BCM harness connector B14 termi-
nals 59 (Y), 70 (SB) and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4. CHECK REAR WIPER TO GROUND
Check continuity between rear wiper motor harness connector D107
terminal 2 (B) and ground.
OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector.
5. CHECK BCM
1. Connect BCM connector and rear wiper motor connector.
2. Turn ignition switch ON.
3. With rear wiper switch ON, check voltage between BCM har-
ness connector B14 terminal 59 (Y) and ground.
OK or NG
OK >> Replace rear wiper motor.
NG >> Replace BCM. Refer to BCS-15, "
Removal and Installation of BCM" . 59 (Y) - 3 (BR) : Continuity should exist.
