REAR WIPER AND WASHER SYSTEM
• to rear wiper motor terminal 3
• through grounds B117, B132 and D402.
With power and ground supplied, the rear wiper motor operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arm at low speed approximately every 7 seconds.
When the combination switch (wiper switch) is in the r ear wiper INT position, the BCM detects a rear wiper INT
request through the combination switch (wiper switch) reading function.
When BCM operates rear wiper motor, power is supplied
• through BCM terminal 55
• to rear wiper motor terminal 1.
Ground is supplied
• to rear wiper motor terminal 3
• through grounds B117, B132 and D402.
With power and ground supplied, the rear wiper operates in intermittent mode.
AUTO STOP OPERATION
When the rear wiper arm is not located at the base of the rear window, and the rear combination switch (wiper
switch) is turned OFF, the rear wiper motor will continue to operate until the rear wiper arm is at the base of the
rear window. When the rear wiper arm reaches the bas e, rear wiper motor terminals 2 and 1 are connected.
Ground is supplied
• to BCM terminal 44
• through rear wiper motor terminal 2, and
• through rear wiper motor terminal 3, and
• through grounds B117, B132 and D402.
REAR WASHER OPERATION
When the ignition switch is in the ON or START positi on, and the front and rear washer switches are OFF, the
front and rear washer motor is supplied power
• through 15A fuse [No. 4, located in the fuse block (J/B)]
• to combination switch (wiper switch) terminal 14
• through combination switch (wiper switch) terminal 11
• to front and rear washer motor terminal 2.
When the rear combination switch (wiper switch) is in rear washer position, the BCM detects a rear washer
signal by BCM combination switch (wiper switch) readi ng function. Combination switch (wiper switch) ground
is supplied
• to front and rear washer motor terminal 1
• through combination switch (wiper switch) terminal 13, and
• through combination switch (wiper switch) terminal 12
• through grounds M57 and M61.
With ground supplied, the front and rear washer motor is operated in the rear direction.
When the BCM detects that the rear washer motor has operated for 0.4 seconds or longer, BCM operates the
rear wiper motor.
When the BCM detects that the rear washer switch is in OFF, the rear wiper motor cycles approximately 3
times and then stops.
If the rear washer is operated with the rear combinati on switch (wiper switch) in the INT position, normal rear
wiper operation will take over. Once the rear washer switch is released the rear wiper will return to INT opera-
tion.
