System Descrip-
tion" in “PG IPDM E/R” to make sure that it is not in fail-safe status.
1.ACTIVE TEST
With CONSULT-lIl
1. Select “IPDM E/R” on CONSULT-III, and sele ct “ACTIVE TEST” on “SELECT DIAG MODE” screen.
2. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch “LO” or “HI” screen.
Without CONSULT-lIl
Start up auto active test. Refer to PG-20, "
Auto Active Test" .
Does front wiper operate normally?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK CIRCUIT BETWEEN COMB INATION SWITCH AND BCM
With CONSULT-llI
1. Select “BCM” on CONSULT-III, and sele ct “WIPER” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE ” screen. Make sure that “FR WIPER INT”, “FR
WIPER LOW”, and “FR WIPER HI” turn ON-OFF according to wiper switch operation.
Without CONSULT-lIl
Refer to LT-66, "
Combination Switch Inspection" .
OK or NG
OK >> GO TO 3.
NG >> Check combination switch (wiper switch). Refer to LT-66, "
Combination Switch Inspection" .
3.CHECK CIRCUIT BETWEEN IPDM E/R AND BCM
Select “BCM” on CONSULT-III, and perform self-diagnosis for “BCM”.

-diagnosis results
NO DTC>>Replace BCM. Refer to BCS-19, "Removal and Installation of BCM" .
CAN COMM CIRCUIT>>Check CAN communi cation line of BCM. Refer to BCS-18, "
CAN Communication
Inspection Using CONSULT-III (Self-Diagnosis)" .
4.CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect front wiper motor.
3. Check continuity between front wiper motor connector and ground.
OK or NG
OK >> GO TO 5.

Front Wiper Does Not Return to Stop Positi on (After Front Wiper Operates for 10 Sec-
onds, They Stop for 20 Second s, and After Repeating the Operation Five Times, They
Become Inoperative)
INFOID:0000000005395066
CAUTION:
• When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front wip-
ers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this symp-
tom.
• This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROT” item
shows “BLOCK”.
1.CHECK FRONT WIPER STOP SIGNAL
With CONSULT-lIl
Select “IPDM E/R” on CONSULT-III. With “DATA MONITOR”, make sure that “WIP AUTO STOP” turns “ACT
P” - “STOP P” linked with wiper operation.
Without CONSULT-llI
GO TO 2.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-28, "Removal and Installation of IPDM E/R" .
NG >> GO TO 2.
2.CHECK IPDM E/R
1. Turn ignition switch ON.
2. Check voltage between IPDM E/R connector and ground while front wiper motor is stopped and while it is operating.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-28, "Removal and Installation of IPDM E/R" .
NG >> GO TO 3.
3.CHECK FRONT WIPER AUTO STOP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R and wiper motor.
3. Check continuity between IPDM E/R connector (A) and front wiper motor connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
ground.
