If the wiper does not operate at high speed even in heavy rain, check th\
e pins 1 and 2.
In other words, the wiper should operate at high speed when grounding th\
e pins 1 and 2.Symptom 5. The wiper does not operate at high speed even in heavy rain.
Symptom 6. The wiper responses are too fast or slow.
Check whether the variable resistance knob on the multifunction wiper sw\
itch is set in "FAST"
or "SLOW".
Notify that the customer can select the sensitivity by selecting the variable resistance value.
And, select a proper stage.

▶Auto Light ControlThe 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 switc\
h "ON".
-
Rain detected headlamp: If it rains heavy which requires the highest INT speed (almost LOW),
the headlamps are turned on automatically.
-
Night detected wiping: When the auto light control turns on the headlamp\
s and the rain senso
r
detects the rain, the wiper sensitivity is automat ically increased by one level in comparison with
daytime.
(i.e. the AUTO wiper switch is at the 3rd level, but the wiper operates\
at the 4th level.)

Enlarged auto light sensor
Emitter lens
The LED emitting the infrared
rays is installed on the bottom
and the lens guides the infrared
rays to target point.

▶Volume Sensitive INT (Intermittent) Wiper
For RKSTICS without the rain sensor, perform the following operation:
Controls the wiper intermittent operation by the values from the vehicle\
speed and the volume
(resistance).
-
Calculates and converts the Intermittent interv al automatically by obtaining the INT VOLUME
when the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitiv e mode when turning the INT switch to the
"ON" position with the engine running or starting the engine with the INT switch positioned to
"ON".
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds

Vehicle speed calculation
-
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
VOLUME calculation
-
The pause time of the vehicle speed sensitive INT wiper is calculated by\
the INT volume (inpu
t
voltage). Each level has the hysteresis.
˙
Pause time calculation
-
Pause time means the duration that wipers are stopped at parking positio\
n.
Elapsed time means the duration after the wiper motor started to operate from parking
position.
The pause time is calculated by the vehicle speed and the VOLUME.
※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.

1 [PULSE/SEC] =
637 × 4 PULSE ≒ 1.41 [km/h]

Cautions for wiper control1. Speed sensitive INT (intermittent) wiper
The wiper relay continues to output for remaining "ON" time even when the INT switch is
turned off during its operation.
IGN switch "ON", INT switch "OFF": Resume the intermittent time when tur\
ning "ON"
IGN switch "OFF", INT switch "ON": Resume the intermittent time when tur\
ning "ON"
1)
2)
3)
2. Controls when the wiper motor parking is defective The wiper relay continues to output when the parking terminal is fixed at the ground or IGN
while the wiper relay is "ON" (INT switch = ON or washer switch = ON)
(The output stops immediately after turning off the switch)

▶Ignition Key Reminder WarningThe chime buzzer sounds continuously when opening the driver's door whil\
e 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 does not work when the IGN1 switch is in "ON" position.

▶Ignition Key ReminderThe 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 ign\
ition switch).
The system outputs "UNLOCK" signal for 5 seconds 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 ch\
anged from "UNLOCK" to
"LOCK", the system does not output "UNLOCK" signal.

▶All Door Lock Prevention Function when a Door is OpenAll 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 do\
ors is open).
When the door is closed during the UNLOCK output for approx. 5 seconds, the UNLOCK output
stops immediately.
When the ignition key is inserted during the 5 seconds 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.

▶Tail Lamp Left On WarningThe chime buzzer sounds with the interval of 0.8 second when opening the\
driver's door while the
tail lamp is turned on and the ignition key is removed.
The c/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 p\
assenger's door lock
switch is locked (while the tail lamp is turned on and the driver's doo\
r is open).
This function does not work when the IGN1 switch is in "ON" position.
