Emitter lens
The LED which is located at
bottom emits the infrared rays and
the lens guides the infrared rays to
target point.
Auto light sensor

Auto light sensor (Vertical)
Auto light sensor (Horizon)
Wiper (HI, LO) relays
Used 3-way relay consisting of 5-pinSTICS
It receives the signals regarding the rain
sensor, multifunction wiper switch and
vehicle speed to control the wiper system
with the various functions.
Multifunction wiper switches
AUTO: Wiper operates automatically by rain
sensor
FAST to SLOW: Auto delay/auto speed control. A
position that can control sensitivity against rains
on the windshield and transmits wiping demand
signal accordingly.
Wiper relay (LO) Wiper relay (HI)
Rain sensor unit
Integrated into the auto light sensor. Detects and sends amount of rain drops to STICS

3) STICS Control Logic Related to Wiper and Washer
Wiper MIST and Front Washer Coupled Wiper ▶
The wiper relay is turned on 0.3 seconds after turning "ON" the washer switch for 0.1 ~ 0.59
seconds with the ignition key "ON", and it is turned off when the parking terminal is turned off. 1.
The wiper relay is turned on at 0.3 seconds after from the time when the washer switch is turned
on for more than 0.6 seconds with the ignition switch "ON". The wiper relay gets on 3 times
immediately after turning off the washer switch. 2.

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 LOW relay
operates to drive the wiper motor for 1 cycle only if data from the rain sensor indicates rain
drops. 2.

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.

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.

Cautions for wiper control ※
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 turning "ON".
IGN switch "ON", INT switch "ON": Resume the intermittent time when turning "ON". -

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

2) EBD (Electronic Brake-force Distribution) Warning Lamp
EBD warning lamps (brake warning lamp and ABS warning lamp) come on when the system performs
the self diagnosis and when it detects the malfunction of EBD system. However, the brake warning lamp
comes on regardless of EBD system when the parking brake is applied.
EBD warning lamp ON:
When turning the ignition switch to ON position, ABS warning lamp and the brake warning lamp
comes on for 3 seconds for self diagnosis and goes off if the system is OK (initialization mode).
When applying the parking brake, the brake warning lamp comes on.
When the brake fluid is not sufficient, the brake warning lamp comes on.
When disengaging the connector, the warning lamp comes on.
When the system is defective, ABS warning lamp and the brake warning lamp come on
simultaneously. A.
