Rain sensing unit
(AUTO light integrated type)
▶INT Switch Auto Position Remi nder (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, regar\
dless of the rain
sensor communication.
After that, when turning the INT-AUTO switch fr om the "OFF" to "ON" position, the LOW 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 senso
r
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

▶Sensitivity ControlThe 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.

▶Defective Rain SensorThe 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 sign\
al from the rain sensor,
while the ignition key is in "ON" position and the wiper switch is in "O\
N" position.

The wiper relay (LOW) is turned on and the wiper motor runs one cycle when the volume
sensitivity is changed to 3 from 4 during receiving the malfunction sign\
al from the rain sensor,
while the ignition key is in "ON" position and the wiper switch is in "O\
N" 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 (Groun\
d) and the pin 4
(IGN).
Check the wiper relay for defective.

Symptom 2. It rains but the system does not work in "AUTO" position.
TROUBLE SHOOTING
▶
The wiper does not operate one cy cle when turning the multifunction
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 sw\
itch 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 i\
s set in
"FAST". The "FAST" is the highest stage of sensitivity and very sensitive to small amount o
f
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 o
f
rain drops. Therefore, change the knob to low sensitivity.

Cautions for wiper control1. Speed sensitive INT (intermittent) wiper
The wiper relay continues to output for remaining "ON" time even when the INT switch is
turned off during its operation.
IGN switch "ON", INT switch "OFF": Resume the intermittent time when tur\
ning "ON"
IGN switch "OFF", INT switch "ON": Resume the intermittent time when tur\
ning "ON"

2)
3)
2. Controls when the wiper motor parking is defective The wiper relay continues to output when the parking terminal is fixed at the ground or IGN
while the wiper relay is "ON" (INT switch = ON or washer switch = ON)
(The output stops immediately after turning off the switch)

ignition switch.
When removing the ignition key or closing the driver's door during chime\
buzzer operation, the
buzzer stops.
This function does not work when the IGN1 switch is in "ON" position.

▶STICS Circuit for Tail Lamp Auto Cut (Battery Saver)
▶Tail Lamp Auto Cut (Battery Saver) The tail lamp is turn on or off according to the operations of the tail \
lamp switch.
The tail lamp relay is turned off (auto cut) when opening and closing the driver's door afte
r
removing the ignition key without turning off the tail lamp.
The tail lamp relay is turned on when inserting the ignition key into th\
e ignition switch.
The tail lamp relay is turned off (auto cut) when opening and closing the driver's door while the
ignition key is removed and the tail lamp is turned on.
