STICS
If the washer operating signal is inputted while the wipers are operating in intermittent or
AUTO mode, the system stores the previous intermittent interval and operates the washe
r
coupled wiper. After then, the wiper operation returns back to intermittent or AUTO mode
with the stored operating interval. 3.

(2) Rain Sensor Coupled Wiper
If equipped with RE-STICS rain sensor, has following operation system.
System layout ▶
This vehicle has a different wiper control logic compared to other models. As shown in the
system diagram, the rain sensor unit does not control wiper directly. The rain sensor unit sends
infrared rays signal through LED and then receives it with photo diode and then sends the
returned signal to STICS and the STICS controls the wipers directly.
For more details, refer to rain sensing wiper section in this manual.

STICS
(3) Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed
and INT VOLUME when the ignition switch is in “ON” position and the INT switch is in
“ON” position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch
to “ON” position with the engine running or starting the engine with the INT switch
positioned “ON”.
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds -

-
2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the
table in next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·

Rain sensor unit (including cover)
2. RAIN SENSOR OPERATION
The rain sensor is installed on the specific heat treated windshield that has minimum 13% of
transmittance rate with specified intensity of radiation. It is installed on the glass with a
adhesive of Sorepa.
It communicates with STICS and makes the wipers to operate automatically under the rain
sensing mode (multifunction switch wiper: AUTO mode).
The emitting section of the rain sensor unit emits infrared rays against the windshield and then
detects the amount of rain drops by receiving reflected rays with photodiode.
The sensing section on the windshield is located just above the center point between LED and
photodiode.

4. FUNCTIONS OF RAIN SENSOR
1) Windshield Glass and Coupler Attachment
Check the outer windshield surface of sensing area for wear, damage and scratch. The sensor
is able to compensate the wear up to a specific level. Check the coupler attached surface of
windshield for porosity. If the porosity exists, the sensor cannot function properly.
2) Recognition of AUTO Mode
3) Instant Wipe Function
When the variable resistance knob on the multifunction wiper switch is turned by each 1 stage
from low sensitivity (Smark) to high sensitivity (F mark), the wiper operates one cycle.
And, the wiper also operates during raining up to 5 minutes after rain stops.When the engine is started with the wiper switch “AUTO” position, the wiper operates
one cycle to remind a driver that the wiper switch is in “AUTO” position.
When the 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. 2 terminal on the rain sensor. If any defective
cannot be found, check the wiper relay (LOW) for defective. 1)
2)
3)If the installed wiper brushes are out of specification (size and length), the rain sensing
area cannot be fully wiped. In this case, the rain sensor’s sensitivity could be
decreased and the wipers are not properly operated -
As described, the STICS recognizes the wiper switch “AUTO” position. If there are not
any problem, go to diagnosis mode in STICS and check the terminal that receives signal
from wiper and communication lines between rain sensor unit and STICS. -
