▶ 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.

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. ·

▶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. CAUTIONS ON RAIN SENSOR
When the wiper switch is in the AUTO position, the wiper will operate for 1 cycle if the initial
engine start is made. This may cause the wiper blades to wear prematurely. Therefore, other
than rainy days, set the switch to the OFF position. Especially during the winter time, check if
the wiper blades are not frozen to the windshield.
Operating the wiper with the blades frozen can damage the wiper motor.
If you operate the wipers when the windshield is dry without spraying washer fluid, the
windshield can be scratched and the wiper blades can wear prematurely. Use the wiper with the
washer fluid when the windshield is dry.
When it does not rain, turn the wiper switch to the OFF position.
Turn the wiper switch to the OFF position before any car wash to avoid unwanted operation of
the wipers. -
-
-
-
When cleaning the windshield over the sensor with damp clothes, the wiper may operate
suddenly. It could cause serious injury. Make sure to place the wiper switch to the OFF
position and ignition switch OFF when not in use.
Irregular operation (abrupt operation) ▶
Check if the sensor is off the position.
Check if the rain sensor cover is securely installed.
Check if the customer is familiar to how to control the wiper sensitivity.
Check if the wiper sensitivity control is set to the FAST side (step 5).
Check the wiper blade for wear.
If the wiper blade cannot wipe the glass uniformly and clearly, it may cause the rain sensor to
work irregularly. Therefore, in this case, replace the wiper blade with a new one. -

The rain sensing wiper unit in this vehicle doesn’t control the wiper directly.
The rain sensing unit detects the amount of rain drops and sends the operating signal to STICS,
and STICS drives the wiper directly.
1. SYSTEM LAYOUT AND OVERVIEW
Rain sensing unitMultifunction wiper switch:
AUTO and sensitivity control
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
: Wiper operates automatically by rain sensor
FAST <-------> SLOW
: Auto delay/Auto speed control. A position
that can control sensitivity against rains on
the windshield and transmits wiping demand
signal accordingly.
Emitter lens
The LED which is located
at bottom emits the
infrared rays and the lens
guides the infrared rays to
target point.

STICS
The rain sensing unit detects the amount of rain drops and sends
the operating signal to STICS, and STICS drives the wiper directly.
At this moment, STICS determines the wiper operation mode
(washer, MIST, AUTO), then sends the information to the rain
sensor.

2. RAIN SENSOR OPERATION
The rain sensor is installed on the specific heat treated windshield that has minimum 13% of
transmittance rate with specified intensity of radiation. It is installed on the glass with a adhesive
of Sorepa.
It communicates with STICS and makes the wipers to operate automatically under the rain
sensing mode (multifunction switch wiper: AUTO mode).
The emitting section of the rain sensor unit emits infrared rays against the windshield and then
detects the amount of rain drops by receiving reflected rays with photodiode.
The sensing section on the windshield is located just above the center point between LED and
photodiode.

1) Rain Sensor Coupled Wiper
▶ System layout
This vehicle has a different wiper control logic compared to other models. As shown in the
system diagram, the rain sensor unit does not control wiper directly. The rain sensor unit sends
infrared rays signal through LED and then receives it with photo diode and then sends the
returned signal to STICS and the STICS controls the wipers directly.
For more details, refer to rain sensing wiper section in this manual.
