2. FUNCTIONS OF RK STICS
1) Wiper Control
(1) Wiper MIST and Washer Coupled Wiper
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch for 0.2 ~
0.59 seconds (T2) with the ignition key “ON”, and it is turned off when the parking terminal
is turned off. 1.
The wiper relay is turned on 0.3 seconds (T1) after turning “ON” the washer switch over 0.6
seconds (T2) with the ignition key “ON”, and it is turned on three times immediately after
turning off the washer switch. 2.

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 washer 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
▶ 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)
