4) Rear Washer Control Function
The rear washer motor is operated only when the rear washer switch is activated with the ignition
key ON.
If the front washer or automatic washer switch signal is received during the rear washer switch
operation, the washer motor stops and the front washer or automatic washer motor begins to
operate. 1.
2.Rear washer motor control
When the switch is fully turned, washer fluid will be
sprayed onto the rear window glass and the wiper
will also operate. When the switch is released, it will
wiper and washer.

AUTO operation and sensitivity control
5) Rain Sensor Coupled Wiper Control Function
AUTO: Wiper operates automatically by rain sensor
FAST <----> Auto delay/auto speed control
A position that can control sensitivity against rains on the
windshield and transmits wiping demand signal accordingly.

System layout
(1) Rain sensor coupled wiper operation (LIN)

If the intermittent/automatic wiper switch is in &#34;ON&#34; position, the wiper motor does not operate even
when turning the ignition switch to ON from OFF position.
When the INT/AUTO wiper switch is turned on from off with the ignition switch ON, the wiper is
operated at low speed for the 1st cycle regardless of the rain sensor signals. After that, if the
INT/AUTO wiper switch is turned on from off, the wiper cycles one time at low speed only when the
rain sensor detects the presence of rain. 1.
2.
(2) Power-up reminder wiper

7810-00
When the washer switch signal is received during intermittent operation coupled with rain sensor
with IGN ON and intermittent/automatic
washer switch operation, the wipers operate in washer coupled mode regardless of the
communication with the rain sensor. However, if the washer switch
signal is received the washer relay is activated and wiper relay remains activated,
when the data coupled with rain sensor indicates continuous wiper operation.
Even though the wiping system is in washer coupled wiper mode, the operating data are sent to
rain sensor. 1.

(3) Washer coupled wiper operation during rain sensor coupled operation

When the wiping speed control switch is turned to &#34;FAST&#34; with IGN2 ON, intermittent/automatic wiper
switch in &#34;ON&#34; position and wiper motor stop (parking position), the wiper motor operates one cycle a
t
low speed.
(only when the rain sensor detects raindrops)
If the wiping speed control switch is changed more than 2 stages within 2 seconds, the wiper motor
operates only one cycle. 1.
*
(4) Sensitivity control (instant wiping)

7810-00
When the parking terminal is shorted to power with IGN2 ON and intermittent wiper switch in &#34;ON&#34;
position, the wiper system sends the signal for current wiping status for 2 seconds. After that, it
sends the current signal for parking status continuously.
* The wiper motor is operated only when there is a request from the rain sensor. 2.
The wiper system sends continuously the signal for current status when the wiper parking terminal
is shorted to ground with IGN2 ON and intermittent wiper switch in &#34;ON&#34; position.
* The wiper motor is operated only when there is a request from the rain sensor. 1.
(5) For abnormal wiper parking signal

When the wiper speed control switch is turned to step 3 from step 4 the wiper motor cycles one time
at low speed, provided that the BCM receives a communication error signal from the rain sensor uni
t
with IGN ON and the INT/AUTO switch ON. 2.
When the wiper speed control switch is turned to step 2 from step 3 the wiper motor cycles one
time at low speed, provided that the BCM receives a faulty sensor signal from the rain sensor unit
with IGN ON and the INT/AUTO switch ON. 1.
(6) For faulty rain sensor

7810-00
For the vehicles without rain sensor, the BCM operates the wiper as follows:
When turning the ignition switch to ON from OFF position with the intermittent wiper switch in &#34;ON&#34;
position, the wipers do not operate.
When turning the wiper switch to ON from OFF position after turning the ignition switch to ON position,
the wipers operate one cycle.
The wiper&#39;s operation cycle depends on the vehicle speed (CAN communication with instrument
cluster) and wiping speed the side fascia panel.
