System Description
EKS00FZX
●
The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-
minals. Terminal combination status is read by the BCM (body control module) when switch is turned ON.
●
The BCM controls rear wiper ON and INT (intermittent) operation.
Power is supplied at all times
●
through 50A fusible link (letter g , located in fuse and fusible link box)
●
to BCM terminal 70.
With the ignition switch in ON or START position, power is supplied
●
through 10A fuse [No. 15, located in the fuse block (J/B)]
●
to combination switch terminal 2, and
●
through 10A fuse [No. 1, located in the fuse block (J/B)]
●
to BCM terminal 38.
Ground is supplied
●
to BCM terminal 67 and
●
to combination switch terminal 9
●
through grounds M57, M61 and M79.
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.
The BCM will first check the status of the glass hatch ajar switch before supplying power to the rear wiper
motor. If the glass hatch ajar switch is closed (grounded) the BCM will not turn on the rear wiper motor. If the
glass hatch ajar switch is open (not grounded) the BCM will control the rear wiper motor as follows.
Power is supplied
●
through BCM terminal 55
●
to rear wiper motor terminal 4.
Ground is supplied
●
to rear wiper motor terminal 1
●
through grounds D406 and D504.
With power and ground supplied, the rear wiper motor operates.

REAR WIPER AND WASHER SYSTEM

If the BCM detects the glass hatch ajar switch signal during rear wiper motor operation, the BCM will operate
the rear wiper motor to the auto stop position. Once the glass hatch ajar switch signal returns to open (not
grounded) for 5 or more seconds, the BCM will resume rear wiper motor operation.
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 4.
Ground is supplied
●
to rear wiper motor terminal 1
●
through grounds D406 and D504.
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 1
●
through grounds D406 and D504.
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 10A fuse [No. 15, located in the fuse block (J/B)]
●
through combination switch (wiper switch) terminal 2
●
through combination switch (wiper switch) terminal 3
●
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 4
●
through combination switch (wiper switch) terminal 9
●
through grounds M57, M61 and M79.
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.
