Auto Switch Position Reminder (Power-Up Reminder Wiper)
When turning off and on the IGN2 switch with the auto switch on, the system drives the
wiper motor through LOW relay one cycle regardless of communication with rain sensor.
The wiper relay (LOW) is turned on and the wiper motor runs one cycle when changing the
auto switch from "OFF" to "ON" position regardless of communication with rain sensor(while
the ignition key is in the "ON" position).
When the auto switch is turned to the "ON" position again from the "OFF" position, the
system drives the wiper motor through LOW relay one cycle only when the rain senso
r
detects the "Rain Detected" signal. 1.

Multifunction wiper switch:
AUTO and sensitivity controlRain sensing unit
(auto light integrated type)
A sensor that emits infrared rays through
LED and then detects the amount of rain
drops by receiving reflected rays against
sensing section (rain sensor mounting
section on the windshield) with photodiode
(auto light sensor integrated type)AUTO: Wiper operates automatically by
rain sensor FAST
SLOW: Auto
delay/Auto speed control. A position that
can control sensitivity against rains in the
windshield and transmits wiping demand
signal accordingly

Washer Coupled Wiper in Rain Sensing Mode
The washer coupled wiper is operated when receiving the washer switch input with the
ignition switch "ON" and the AUTO switch "ON" in the rain sensing mode. At this moment,
the communication with the rain sensor is overridden. However, the washer switch input is
overridden during the continuous operation.
The operation data is sent to the rain sensor even during the washer coupled wiper's
operation. 1.
2.
Rain Sensing Sensitivity Control
The wiper LOW relay is turned on and the wiper motor runs one cycle when the volume
sensitivity is increased (while the ignition key is in the "ON" position, the AUTO switch is in
the "ON" position, and the wiper motor is in "Parked" position). However, the wiper moto
r
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 moto
r
runs only one cycle. *

When the Wiper Parking Signal is Abnormal
The wiper system continuously outputs the wiper parking signal when the wiper parking
terminal is grounded (while the ignition key is in "ON" position and the AUTO switch is in
"ON" position). * The wiper motor runs only when the rain sensor requires the wipe
r
operation. 1.
When the parking terminal is fixed to HIGH with the ignition key and the AUTO switch in
"ON" position, the wiper system outputs the wiper operating signal for 2 seconds, then
continuously outputs the wiper parking signal.
* The wiper motor runs only when the rain sensor requires the wiper operation. 2.

Defective Rain Sensor
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 AUTO switch is in "ON" position). 1.
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 senso
r
(while the ignition key is in "ON" position and the AUTO switch is in "ON" position). 2.

Auto Light Control
The tail lamps and headlamps can be controlled by the communication with the rain sensor
only when the auto light switch is in "AUTO" position with the ignition switch "ON". 1.
Rain detected headlamp: If it rains heavy which requires the highest AUTO speed, the
headlamps are turned on automatically (while the light switch is in "AUTO" position and the
wiper switch is in "AUTO" position).
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. (i.e. the
AUTO wiper switch is at the 3rd level, but the wiper operates at the 4th level.) 2.
3.
Emitter lense
The emitter lens located at bottom of
rain sensing unit guides the infrared
rays from the LED to the target point.

Speed Sensitive AUTO Wiper
For RKSTICS without the rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from the vehicle speed
and the volume.
Calculates and converts the Intermittent interval automatically by using the
AUTO
VOLUME when the ignition switch is in the "ON" position and the AUTO switch is in the
"ON" position.
The wipers are operated in vehicle speed sensitive mode when turning the AUTO switch to
the "ON" position with the engine running or starting the engine with the AUTO switch
positioned to "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 [PULSE/SEC] =
1.41 [km/h] 60 [km/h] x 60 [sec]
637 x 4 PULSE
3. VOLUME calculation
The pause time of the vehicle speed sensitive AUTO wiper is calculated by the
AUTO
volume (input voltage). Each level has the hysteresis. -
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 the VOLUME.

Speed sensitive AUTO wiper -
1) The wiper relay continues to output for remaining "ON" time even when the AUTO switch
is turned off.
2) IGN 2 switch "ON", AUTO switch "OFF": Resume the intermittent time when turning "ON"
3) IGN 2 switch "OFF", AUTO switch "ON": Resume the intermittent time when turning "ON"
Controls when the wiper motor parking is defective -
1) The wiper relay continues to output when the parking terminal is fixed at the ground or
IGN while the wiper relay is "ON" (AUTO switch = ON or Washer switch = ON) (The output
stops immediately after turning off the switch) (The output stops immediately after turning
OFF the switch.)Pause time of vehicle speed sensitive INT wiper AUTO
