1. CHECK IPDM E/R TO FRONT WIPERS
With CONSULT-II
1. Select "IPDM E/R" with CONSULT-II, and select "ACTIVE TEST" on "SELECT DIAG MODE" screen.
2. Select "FRONT WIPER" on "SELECT TEST ITEM" screen.
3. Select "HI" on "ACTIVE TEST" screen.
4. Confirm front wiper high operation.
Without CONSULT-II

"Auto Active Test" .
2. Confirm front wiper operation.
OK or NG
OK >> GO TO 4.
NG >> GO TO 2.
2. IPDM E/R TO FRONT WIPERS CIRCUIT INSPECTION
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connector.
3. Check continuity between IPDM E/R harness connector terminal and front wiper motor harness connector terminal.

3. IPDM E/R INSPECTION
With CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Turn ignition switch ON.
3. Select "HI" on "ACTIVE TEST" screen.
4. When front wiper high relay is operating, check voltage between IPDM E/R terminals.
Without CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Turn on front wipers using the auto active test. Refer to PG-24, "
Auto Active Test" .
3. When front wiper high relay is operating, check voltage between IPDM E/R terminals.
OK or NG
OK >> Replace the wiper motor. Refer to WW-29, "Wiper Motor
and Linkage" .
NG >> Replace IPDM E/R. Refer to PG-30, "
Removal and Installation of IPDM E/R" .
4. COMBINATION SWITCH TO BCM INSPECTION
Select "BCM" on CONSULT-II. With "WIPER" data monitor, check
that "FR WIPER HI" turns ON-OFF according to operation of wiper
switch.
OK or NG
OK >> Replace BCM. Refer to BCS-20, "BCM" .
NG >> Replace wiper switch. Refer to WW-30, "
Wiper and
Washer Switch" .
ONLY FRONT WIPER INTERMITTENT DOES NOT OPERATE
1. COMBINATION SWITCH TO BCM INSPECTION
Select "BCM" on CONSULT-II. With "WIPER" data monitor, check
that "FR WIPER INT" turns ON-OFF according to operation of wiper
switch.
OK or NG

FRONT WIPER INTERMITTENT OPERATION SWITCH POSITION CANNOT BE ADJUSTED
1. COMBINATION SWITCH TO BCM INSPECTION
Select "BCM" on CONSULT-II. With "WIPER" data monitor, check
that "INT VOLUME" changes in order from 1 to 7 according to opera-
tion of the intermittent switch dial position.
OK or NG
OK >> Replace BCM. Refer to BCS-20, "BCM" .
NG >> Replace wiper switch. Refer to WW-30, "
Wiper and
Washer Switch" .
WIPERS DO NOT WIPE WHEN FRONT WASHER OPERATES
1. COMBINATION SWITCH TO BCM INSPECTION
Select "BCM" on CONSULT-II. With "WIPER" data monitor, check
that "FR WASHER SW" turns ON-OFF according to operation of
front washer switch.
OK or NG
OK >> Replace BCM. Refer to BCS-20, "BCM" .
NG >> Replace wiper switch. Refer to WW-30, "
Wiper and
Washer Switch" .
FRONT WIPERS OPERATE FOR 10 SECONDS, STOP FOR 20 SECONDS, AND AFTER
REPEATING THIS OPERATION FIVE TIMES, THEY BECOME INOPERATIVE
CAUTION:

When auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers front wipers locked and stops wiper output, which causes this symp-
tom.

This status can be checked by using IPDM E/R "DATA MONITOR". Under this condition, "WIP
PROT" reads "BLOCK".
1. CHECK IPDM E/R TO FRONT WIPER MOTOR
With CONSULT-II
Select "IPDM E/R" with CONSULT-II. With data monitor, confirm that
"WIP AUTO STOP" changes from "ACT P" to "STOP P" according to
wiper operation.
Without CONSULT-II
GO TO 2.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-30, "Removal and
Installation of IPDM E/R" .
NG >> GO TO 2.
