2. IPDM E/R TO FRONT WIPERS (2) 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.
OK or NG
OK >> GO TO 3.
NG >> Check for short circuit or open circuit in harness
between IPDM E/R and front wiper motor.
3. IPDM E/R INSPECTION
With CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Select "LO" on "ACTIVE TEST" screen.
3. When front wiper 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-22, "
Auto Active Test" .
3. When front wiper relay is operating, check voltage between
IPDM E/R terminals.
OK or NG
OK >> Replace the wiper motor. Refer to WW-31, "Removal and Installation of Wiper Motor and Linkage"
.
NG >> Replace IPDM E/R. Refer to PG-28, "
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, "Removal and Installa-
tion of BCM" .
NG >> Replace wiper switch. Refer to WW-33, "
Removal and
Installation of Wiper and Washer Switch" .

REAR WIPER AND WASHER SYSTEMPFP:28710
Components Parts and Harness Connector LocationEKS00BEB
System DescriptionEKS00BEC

The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-
minals. Terminal combination status is read by the BCM (body control module) when switch is turned ON.

The BCM controls rear wiper ON and INT (intermittent) operation.
Power is supplied at all times

through 50A fusible link (letter f , located in fusible link box)

to BCM terminal 70.
With the ignition switch in ON or START position, power is supplied

through 10A fuse [No. 9, located in fuse block (J/B)]

to combination switch terminal 14, and

through 10A fuse (No. 59, located in the fuse and relay box)

to BCM terminal 38.
Ground is supplied

to BCM terminal 67 and

to combination switch terminal 12

through grounds M57, M61 and M79.
