System DescriptionINFOID:0000000001704536
• Front wiper relays (front wiper relay, front wiper high relay) are located in the IPDM E/R (intelligent power
distribution module engine room).
• Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
Terminal combination status is read by BCM (body control module) when switch is turned ON.
• BCM controls front wiper LO, HI, and INT (intermittent) operation.
• IPDM E/R operates wiper motor according to CAN communication signals from BCM.
OUTLINE
Power is supplied at all times• to ignition relay, located in IPDM E/R, from battery directly,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70,
• through 30A fuse (No. 39, located in IPDM E/R)
• to front wiper relay located in IPDM E/R
• through 15A fuse (No. 52, located in IPDM E/R), and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R.
When ignition switch is in ON or START position, power is supplied • through ignition relay (located in IPDM E/R)
• to front wiper relay (located in IPDM E/R), and

4. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
5. Touch “LO” or “HI” screen.
6. Check voltage between IPDM E/R connector and ground while
front wiper (HI, LO) is operating.
Without CONSULT-llI1. Connect IPDM E/R.
2. Turn ignition switch ON.
3. Start auto active test. Refer to PG-19, "
Auto Active Test" .

FRONT WIPER AND WASHER SYSTEM
OK >> Replace front wiper motor. Refer to WW-19, "Removal and Installation of Front Wiper Drive
Assembly" .
NG >> Replace IPDM E/R. Refer to PG-26, "
Removal and Installation of IPDM E/R" .
Front Wiper Does Not Return to Stop Position (After Front Wiper Operate for 10 Sec-
onds, They Stop for 20 Seconds, and After Repeating the Operation Five Times, They
Become Inoperative)
INFOID:0000000001704547
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-26, "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-26, "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.
