System Description
AKS004X4
●
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 F, located in fusible link block)
●
to BCM (body control module) terminal 55
●
through 10 A fuse [No. 18, located in fuse block (J/B)]
●
to BCM (body control module) terminal 42.
When ignition switch ON or START position, power is supplied
●
through 10 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)]
●
through IPDM E/R (intelligent power distribution module engine room) terminal 44
●
to combination switch terminal 14.
Ground is supplied
●
to BCM (body control module) terminals 49 and 52
●
through grounds E14 and M78
●
to combination switch (wiper switch) terminal 12
●
through grounds M14 and M78.

REAR WIPER OPERATION
When wiper switch is in rear wiper ON position, BCM detect rear wiper ON signal by BCM wiper switch read-
ing function.
When 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 B7 and B20.
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
WW-7, "COMBINATION SWITCH READING FUNCTION"
When BCM operates rear wiper motor, power supplied
●
through BCM terminal 70
●
to rear wiper motor 4.
Ground is supplied
●
to rear wiper motor terminal 2
●
through grounds B7 and B20.
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
WW-7, "COMBINATION SWITCH READING FUNCTION"
switch (wiper switch) ground is supplied
Power is supplied
●
through 10 A fuse [NO. 84, located in IPDM E/R (intelligent power distribution module engine room)]
●
to combination switch terminal 14
●
through combination switch (wiper switch) terminal 11
●
to front and rear washer motor terminal 2
●
to front and rear washer motor terminal 1
●
through combination switch (wiper switch) terminal 13
●
to combination switch (wiper switch) terminal 12
●
through grounds M14 and M78.
With ground supplied, front and rear washer motor is operated.
When BCM detects that front and rear washer motor has operated for. 0.4 seconds or linger, BCM operates
rear wiper motor at low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then stops.
