Component Parts and Harness Connector LocationAKS0057H
System DescriptionAKS0057I
Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.
BCM (body control module) controls rear wiper ON and INT (intermittent) operation.
Power supplied all time
through 50 A fusible link (letter M, located in fusible link block)
to BCM (body control module) terminal 55
through 15 A fuse [No. 22, located in fuse block (J/B)]
to BCM (body control module) terminal 42.
When ignition switch ON or START position, power is supplied
through 15 A fuse [No.1, located in fuse block (J/B)]
to BCM (body control module) terminal 38,
through 10 A fuse [No. 84, located in IPDM E/R (intelligent power distribution module engine room)]
to rear washer motor terminal 1.
Ground is supplied
to BCM (body control module) terminals 49 and 52
through grounds M35, M45 and M85
to combination switch (wiper switch) terminal 12
through grounds M35, M45 and M85.
REAR WIPER OPERATION
When wiper switch is in rear wiper ON position, BCM detects rear wiper ON signal by BCM wiper switch read-
ing function.
BCM operates rear wiper motor, power is supplied

through BCM terminal 70
to rear wiper motor 4.
Ground is supplied
to rear wiper motor terminal 2
through grounds B15 and B45.
With power and ground supplied, the rear wiper operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arms at low speed approximately every 7 seconds.
When wiper switch is in rear wiper INT position, BCM detects rear wiper INT signal by BCM wiper switch read-
ing function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ).
BCM operates rear wiper motor, power supplied
through BCM terminal 70
to rear wiper motor terminal 4.
Ground is supplied
to rear wiper motor terminal 2
through grounds B15 and B45.
With power and ground supplied, rear wiper operates at intermittent.
AUTO STOP OPERATION
With rear wiper switch turned OFF, rear wiper motor will continue to operate until wiper arm reaches rear wiper
stopper.
Then wiper motor turns the other way and wiper arm moves once until wiper arm reaches stopper.
WASHER OPERATION
When wiper switch is in rear wiper washer position, BCM detects rear wiper washer signal by BCM wiper
switch reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ), and combina-
tion switch (wiper switch) ground is supplied
to rear washer motor terminal 2
through combination switch (wiper switch) terminal 13
to combination switch (wiper switch) terminal 12
through grounds M35, M45 and M85.
With ground supplied, rear washer motor is operated.
When BCM detects that rear washer motor has operated for. 0.4 seconds or linger, BCM operates rear wiper
motor low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then stops.
BCM WIPER SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" in BODY CONTROL SYSTEM.

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.
6. INSPECTION END

CONSULT-II FunctionsAKS007AG
CONSULT-II can display each diagnostic item using the following diagnostic test modes: work support, self-
diagnostic results, data monitor and active test through data reception and command transmission via the
BCM CAN communication line.
CONSULT-II OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn the
ignition switch ON.
