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.

Rain sensing operation point ▶
The wiper relay is turned on and the wiper motor runs one cycle when the ignition key is
turned to “ON” position (while the wiper switch is in “AUTO” position).
The wiper relay (LO) is turned on and the wiper motor runs one cycle when changing the
wiper switch to “AUTO” position from any other positions (while the ignition key is in
“ON” position). When the wiper switch is turned to “AUTO” position again from other
positions, the system drives the wiper relay (LO) to run the wiper motor one cycle only when
the rain sensor detects the “Rain Detected” signal. 1)
2)
Rain sensing sensitivity control ▶
The wiper relay is turned on and the wiper motor runs one cycle when the volume sensitivity is
increased (ex: from 0 to 1) (while the ignition key is in “ON” position, the wiper switch is
in “AUTO” 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.

(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. ·
