REAR WIPER OPERATION
When the ignition switch is in the ON or START position, and the rear wiper switch is in the ON position, the
BCM detects a rear wiper ON request through the combination switch (wiper switch) reading function and con-
trols the rear wiper motor as follows.
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 motor operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arm at low speed approximately every 7 seconds.
When the wiper switch is in the rear 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 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 base, rear wiper motor terminals 2 and 1 are connected.
Ground is supplied

to BCM terminal 44

through rear wiper motor terminal 2

through rear wiper motor terminal 3

through grounds B117, B132 and D402.
REAR WASHER OPERATION
When the ignition switch is in the ON or START position, 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 wiper switch is in rear washer position, the BCM detects a rear washer signal by BCM wiper
switch reading function. Combination switch ground is supplied

to front and rear washer motor terminal 1

through combination switch (wiper switch) terminal 13

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 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 operation.
