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.

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

Ignition Key Reminder Warning
(The ignition key reminder warning has priority over the "TAILLAMP ON WARNING".)
The chime bell sounds continuously with the interval of 0.3 seconds when opening the
driver's door while the ignition key is in ignition switch.
When removing the ignition key or closing the driver's door during chime buzzer operation,
the buzzer stops.
This function is not available when the ignition switch is in "ON" position. 1.

Ignition Key Reminder
The system outputs "UNLOCK" signal for 5 seconds after the driver's door is opened and
the door lock switch is changed to "LOCK" (while the ignition key is in ignition switch).
The system outputs "UNLOCK" signal for 5 seconds (T2) when the door lock switch is
changed to "LOCK" from "UNLOCK" and the driver's door is closed within 0.5 seconds
(while the ignition key is in the ignition switch).
If the "UNLOCK" conditions are met, the system outputs "UNLOCK" signal unconditionally.
However, if the ignition key is removed after the door lock switch is changed from
"UNLOCK" to "LOCK", the system does not output "UNLOCK" signal. 1.

All Door Lock Prevention Function when a Door is Open
All doors, except the tailgate and hood, output "UNLOCK" signal for 5 seconds when the
"LOCK" signal is inputted (while the ignition key is removed and one of any doors is open).
When the door is closed during the UNLOCK output, the UNLOCK output stops immediately.
When the ignition key is inserted during the UNLOCK output, the output continues for approx. 5
seconds.
If the ignition switch is in the "ON" position or the ignition switch is removed, the above steps
are performed. If the key is in the key cylinder, the ignition key reminder function is activated.
This function does not work if the vehicle speed is over 10 km/h. 1.

Tail Lamp Left On Warning
The buzzer sounds with the interval of 0.3 second when opening the driver's door while the
tail lamp is turned on and the ignition key is removed.
The buzzer output stops when turning off the tail lamp and closing the driver's door.
The system outputs "UNLOCK" signal for 5 seconds when the driver's and passenger's
door lock switch is locked (while the tail lamp is turned on and the driver's door is open).
This function is not available when the ignition key is in the "ON" position. 1.

Door Ajar Warning
The warning light in instrument panel comes on when opening any of doors including
tailgate while the vehicle speed is below 10 km/h.
The warning light goes off when closing the door under step 1.
The warning light blinks when the vehicle speed is over 10 km/h while the warning light is
turned on.
The warning light blinks when a door is open while the vehicle speed is over 10 km/h.
The warning light goes off when closing the door under step 3.
The warning light comes on when the vehicle speed goes below 10 km/h under step 3. 1.
