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.

The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is
changed to 2 from 3 during receiving the malfunction signal (1) from the rain sensor. 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 2 stages within 2 seconds, the wiper motor
runs only one cycle. ▶ Defective rain sensor
