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.
