The auto washer switch input is overridden during the washer coupled wiper operation.
The auto washer switch input is overridden during the auto washer coupled wiper
operation.
The auto washer switch input is overridden during the rain sensor coupled wiper or vehicle
speed sensitive INT wiper operation.
When the auto INT switch input is received during the auto washer operation, the auto
washer operation stops and the auto INT operation is activated. -

▶Rain Sensor Coupled Wiper and Auto Light Control
If equipped with RKSTICS rain sensor, it has following operation system. -
▶System layout

02-138710-01
Rain sensing unit
(AUTO light integrated type)
▶INT Switch Auto Position Reminder (Power-Up Reminder Wiper)
When turning off and on the auto INT switch, the system drives the wiper motor through
LOW relay regardless of communication with rain sensor.
When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition switch
in the "ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle, regardless
of the rain sensor communication.
After that, when turning the INT-AUTO switch from the "OFF" to "ON" position, the LO
W
relay operates to drive the wiper motor for 1 cycle only if data from the rain sensor
indicates rain drops. -
-
Multifunction wiper switch:
AUTO and sensitivity control
A sensor that emits infrared rays through LED
and then detects the amount of rain drops by
receiving reflected rays against sensing section
(rain sensor mounting section on the
windshield) with photodiode (auto light sensor
integrated type)AUTO: Wiper operates automatically by rain
sensor
FAST↔SLOW: Auto delay/Auto speed control. A
position that can control sensitivity against rains
on the windshield and transmits wiping demand
signal accordingly

▶Washer Coupled Wiper in Rain Sensing Mode
The washer coupled wiper is operated when receiving the washer switch input with the
ignition switch and the INT-AUTO switch "ON" in the rain sensing mode. At this moment,
the communication with the rain sensor is overridden. However, a washer input is overridden
if there is an output for continuous operation.
The operation data is sent to the rain sensor even during the washer coupled wiper's
operation. -

▶Sensitivity Control
The wiper LOW relay is turned on and the wiper motor runs one cycle when the volume
sensitivity is increased (ex: sensitivity 0 ⇒ 1) while the ignition switch and the INT switch is
in the "ON" position, and the wiper motor is in "Parked" position). However, the wiper motor
can be operated only when the rain sensor detects the "Rain Detected" signal.
If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor
runs only one cycle. -

▶When the Wiper Parking Signal is abnormal
The wiper system continuously outputs the wiper parking signal when the wiper parking
terminal is grounded, while the ignition switch is in "ON" position and the INT switch is in
"ON" position. -

When the parking terminal is fixed to IGN, the wiper system outputs the wiper operating
signal for 2 seconds, then continuously outputs the wiper parking signal. -

▶Defective Rain Sensor
The wiper relay (LOW) is turned on and the wiper motor runs one cycle when the volume
sensitivity is changed to 2 from 3 during receiving the malfunction signal from the rain
sensor, while the ignition key is in "ON" position and the wiper switch is in "ON" position. -

Check whether the multifunction wiper switch is in the "AUTO" position.
Check the power to the sensor. Check the conditions of the pin 3 (Ground) and the pin
4 (IGN).
Check the wiper relay for defective. 1)
2)
3) Symptom 2. It rains but the system does not work in "AUTO" position. TROUBLE SHOOTING ▶
The wiper does not operate one cycle when turning the multifunctio
n
wiper switch to the "AUTO" from the "OFF" position or starting the engine
while the wiper switch is in the "AUTO" position.
When starting the engine with the multifunction wiper switch in the "AUTO" position,
the wiper operates one cycle to remind a driver that the wiper switch is in the "AUTO"
position.
When the multifunction wiper switch is turned to "AUTO" from "OFF", the wiper
operates one cycle.
It always operates one cycle for the initial operation, however, the wiper does not
operate afterwards to prevent the wiper blade wear if not raining when turning the
wiper switch to "AUTO" from "OFF". However, the wiper operates up to 5 minutes
after rain stops. If this function does not occur, check No. 8 pin. If the pin is normal,
check the wiper relay related terminals. 1)
2)
Symptom 3. The wiper operates 3 or 4 times at high speed abruptly.
Check whether the variable resistance knob on the multifunction wiper switch is set in
"FAST". The "FAST" is the highest stage of sensitivity and very sensitive to small amount
of rain drops. Therefore, change the knob to low sensitivity.
Symptom 4. The wiper operates continuoulsy even on the dry windshield glass.
Check the wiper blade for wear. If the wiper blade cannot wipe the glass uniformly
and clearly, this problem could be occurred. In this case, replace the wiper blade
with new one.
Check whether the variable resistance knob on the multifunction wiper switch is set
in "FAST" The "FAST" is the highest stage of sensitivity and very sensitive to small
amount of rain drops. Therefore, change the knob to low sensitivity. 1)
2) Symptom 1.
