The wiper relay is turned on and the wiper motor runs one cycle when the volume sensitivity is
increased (ex: from 0 to 1) (while the ignition key is in “ON” position, the wiper switch is in
“AUTO” position, and the wiper motor is in “Parked” position). However, the wiper motor can
be operated only when the rain sensor detects the “Rain Detected” signal.
▶ Rain sensing sensitivity control
If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs only
one cycle. *

The wiper system continuously outputs the parking signal of current sensitivity when the parking
terminal is grounded (while the ignition key is in “ON” position and the wiper switch is in
“AUTO” position). 1)
※ The wiper motor runs only when the rain sensor requires.
When the parking terminal is fixed to IGN (HIGH), the wiper system outputs the operating signal of
current sensitivity for 2 seconds, then continuously outputs the parking signal of current sensitivity. 2)
※ The wiper motor runs only when the rain sensor requires.

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

The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is
changed to 3 from 4 during receiving the malfunction signal (2) from the rain sensor (while the
ignition key is in “ON” position and the wiper switch is in “AUTO” position). 2)
The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is
changed to 2 from 1 during receiving the malfunction signal (3) from the rain sensor (while the
ignition key is in “ON” position and the wiper switch is in “AUTO” position). Also, the wiper
relay (LO) is turned on and the wiper motor runs one cycle when the wiper sensitivity is changed to 2
from 1 during receiving the ground fixed or IGN fixed signal from the rain sensor. 3)

▶ Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed and INT
VOLUME when the ignition switch is in “ON” position and the INT switch is in “ON”
position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch to
“ON” position with the engine running or starting the engine with the INT switch positioned
“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 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
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 VOLUME value as shown in the table in
next page. -
-
-
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. ·

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) - (1) Wiper MIST and washer coupled wiper
When turning on the washer switch while the wiper relay is operating.
1)
If the wiper relay “ON” request time is shorter than the remained “ON” time, it is
disregarded. -
(2) Speed sensitive INT (intermittent) wiper
The wiper relay continues to output for remaining “ON” time even when the INT switch is
turned off.
IGN 2 switch “ON”, INT switch “OFF”: resume the intermittent time when turning “ON
IGN 2 switch “OFF”, INT switch “ON”: resume the intermittent time when turning “ON 1)

▶INT Switch Auto Position Reminder (Power-Up Reminder Wiper)
When turning off and on the auto INT switch, the system drives the wiper motor through LOW
relay regardless of communication with rain sensor.
When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition switch in
the "ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle, regardless of the
rain sensor communication.
After that, when turning the INT-AUTO switch from the "OFF" to "ON" position, the LOW relay
operates to drive the wiper motor for 1 cycle only if data from the rain sensor indicates rain
drops. 1.

2) Ignition Key Reminder
▶Key Reminder Warning
The chime buzzer output in the ICM box continues when opening the driver’s door while the
ignition key is inserted into ignition switch.
When removing the ignition key or closing the driver’s door during chime buzzer output, the
output turns off.
This function is not available when the ignition switch is “ON”. 1.
