2. CONFIGURATION (INCLUDING RAIN SENSOR)
Auto washer switch
Pressing the switch makes washer fluid to be
sprayed for 2 sec. with four wiping, and washer
fluid to be sprayed for 1.5 sec. with three
wiping, with no delay of time
Front nozzle
Installed on both sides of the cowl grille
assembly (one on each side). Sprays
washer fluid in fan-shape to cover the
windshield area as much as possible.
Washer reservoir tank
Tank that supplies washer fluid to front washer
systemIntegrated into the auto light sensor.

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 Engine Compartment Fuse Box
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 LO
W
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

08-6
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.
