(3) Turn signal lamp (Hazard warning lamp operation)
The B+ power supplied through the No. F66 interior fuse on the right-hand of the engine
compartment is on standby on the No. 30 and 86 hazard warning lamp relay terminals via the ICM
No. 18 terminal.
The STICS activates and/or controls the hazard warning lamp relay using the No. A26 terminal
depending on the operating conditions. The activated relay supplies the No. 87 and 87a terminals
with the power, which is on standby on the No. 30 hazard warning lamp relay terminal.
The supplied power flows to the corresponding circuit via the No. 7 and 16 ICM terminals.

(4) Windshield de-icer operation
The B+ power supplied through the No. Ef14 fuse and relay box in the engine compartment is on
standby on the No. 30 and 86 windshield de-icer relay terminals via the ICM No. 10 terminal.
The STICS activates and/or controls the windshield de-icer relay using the No. A4 terminal
depending on the operating conditions. The activated relay supplies the No. 87 terminal with the
power, which is on standby on the No. 30 windshield de-icer lamp relay terminal.
The supplied power flows to the windshield de-icer circuit via the No. 1 ICM terminal.

Check whether the multifunction wiper switch is in the "AUTO" position.
Check the power to the sensor. Check the conditions of the pin 3 (Ground) and the pin
4 (IGN).
Check the wiper relay for defective. 1)
2)
3) Symptom 2. It rains but the system does not work in "AUTO" position. TROUBLE SHOOTING ▶
The wiper does not operate one cycle when turning the multifunctio
n
wiper switch to the "AUTO" from the "OFF" position or starting the engine
while the wiper switch is in the "AUTO" position.
When starting the engine with the multifunction wiper switch in the "AUTO" position,
the wiper operates one cycle to remind a driver that the wiper switch is in the "AUTO"
position.
When the multifunction wiper switch is turned to "AUTO" from "OFF", the wiper
operates one cycle.
It always operates one cycle for the initial operation, however, the wiper does not
operate afterwards to prevent the wiper blade wear if not raining when turning the
wiper switch to "AUTO" from "OFF". However, the wiper operates up to 5 minutes
after rain stops. If this function does not occur, check No. 8 pin. If the pin is normal,
check the wiper relay related terminals. 1)
2)
Symptom 3. The wiper operates 3 or 4 times at high speed abruptly.
Check whether the variable resistance knob on the multifunction wiper switch is set in
"FAST". The "FAST" is the highest stage of sensitivity and very sensitive to small amount
of rain drops. Therefore, change the knob to low sensitivity.
Symptom 4. The wiper operates continuoulsy even on the dry windshield glass.
Check the wiper blade for wear. If the wiper blade cannot wipe the glass uniformly
and clearly, this problem could be occurred. In this case, replace the wiper blade
with new one.
Check whether the variable resistance knob on the multifunction wiper switch is set
in "FAST" The "FAST" is the highest stage of sensitivity and very sensitive to small
amount of rain drops. Therefore, change the knob to low sensitivity. 1)
2) Symptom 1.

▶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 interval automatically by obtaining the IN
T
VOLUME when the ignition switch and the INT switch is in the "ON" position.
The wipers are operated in vehicle speed sensitive 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
(input voltage). Each level has the hysteresis. ˙
Pause time calculation -
Pause time means the duration that wipers are stopped at parking position.
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. ˙

˙60 [km/h] × 60 [sec]

637 × 4 PULSE≒ 1.41 [km/h]

▶Ignition Key Hole Illumination
The ignition key hole illumination comes on when opening the driver's door or passenger's
door while the ignition key is removed.
The ignition key hole illumination stays on for 10 seconds when closing the door after step
(1).
The output stops when the ignition key is turned to the "ON" position.
The output stops when receiving the lock signal from the remote control key and entering
armed mode. 1.
