Multifunction Wiper Switch:
AUTO and Sensitivity Control
1. OVERVIEW
The rain sensing wiper unit system doesn't control the wiper directly. The rain sensing unit detects the
amount of rain drops and sends the operating signal to STICS, and STICS drives the wiper directly.
Rain Sensing Unit
(AUTO Light Sensor Integrated Type)
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. The auto light sensor is
Integrated into the rain sensor (refer to the below
picture).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.
Emitter lens
The LED which is located at
bottom emits the infrared rays and
the lens guides the infrared rays to
target point.

STICS ▶
The rain sensing unit detects the amount of rain drops and sends the operating signal to STICS, and
STICS drives the wiper directly. At this moment, STICS determines the wiper operation mode (washer,
MIST, AUTO), then sends the information to the rain sensor.
Auto Light Sensor and Rain Sensor Coupled Control ▶
Rain detected headlamp: If it rains heavy which requires the highest INT speed (almost LOW),
the headlamps are turned on automatically. -
Night detected wiping: When the auto light control turns on the headlamps and the rain sensor
detects the rain, the wiper sensitivity is automatically increased by one level in comparison with
daytime.
(i.e. the AUTO wiper switch is at the 3rd level, but the wiper operates at the 4th level.) -Wiper relay (HI)

1) Power-up Reminder Wiper Function
When turning off and on the auto INT switch, the system drives the wiper motor through LOW
relay regardless of communication with rain sensor. 1.
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 LOW relay
operates to drive the wiper motor for 1 cycle only if data from the rain sensor indicates rain
drops. 2.
2. FUNCTIONS OF RAIN SENSING WIPER

2) Washer Coupled Wiper in Rain Sensing Mode
The washer coupled wiper is operated when receiving the washer switch input with the ignition
switch "ON" and the auto INT switch "ON" in 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. 1.

3) Sensitivity Control
The wiper LOW relay is turned on and the wiper motor runs one cycle when the volume
<009a008c0095009a0090009b0090009d0090009b00a000470090009a004700900095008a0099008c0088009a008c008b0047004f008c009f00610047009a008c0095009a0090009b0090009d0090009b00a00047005700470d7d0047005800500047009e00

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. 1.
If the volume sensitivity is changed more than 1 stage within 2 seconds, the wiper motor runs only
one cycle.
4) Auto Light Control
Only when the auto light switch is in "AUTO" position, it controls the tail lamp and headlamp by
communicating with the rain sensor (while the ignition key is in "ON" position). 1.

5) When Wiper Parking Signal is Abnormal
The wiper system continuously outputs the parking signal of current sensitivity when the parking
terminal is grounded (while the ignition key is in "ON" position and the INT switch is in "ON"
position). 1.
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.
※ The wiper motor runs only when the rain sensor requires the wiper operation. 2.

6) Defective Rain Sensor
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 signal from the rain sensor,
while the ignition key is in "ON" position and the wiper switch is in "ON" position. 2.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. 1.

7) Speed Sensitive INT Wiper
Calculates and converts the Intermittent interval automatically by obtaining the INT VOLUME when
the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitive mode as soon as turning the INT auto switch to
the "ON" position with the ignition key ON or turning the ignition key to the "ON" position with the INT
auto switch ON.
This applies to the vehicle without the rain sensor. -

Controls the wiper intermittent operation by the values from the vehicle speed and the setting value.
