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.
▶ Wiper operation when the wiper parking terminal is grounded

08-10
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

08-118610-11
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)
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)

3. OPERATION MODE OF RAIN SENSING WIPER SYSTEM

08-138610-11
4. FUNCTIONS OF RAIN SENSOR
1) Windshield Glass and Coupler Attachment
Check the outer windshield surface of sensing area for wear, damage and scratch. The sensor is able
to compensate the wear up to a specific level. Check the coupler attached surface of windshield for
porosity. If the porosity exists, the sensor cannot function properly.
2) Recognition of AUTO Mode
3) Instant Wipe Function
When the variable resistance knob on the multifunction wiper switch is turned by each 1 stage from
low sensitivity (S mark) to high sensitivity (F mark), the wiper operates one cycle.
And, the wiper also operates during raining up to 5 minutes after rain stops.When the engine is started with the wiper switch “AUTO” position, the wiper operates one
cycle to remind a driver that the wiper switch is in “AUTO” position.
When the wi
per 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. 2 terminal on the rain sensor. If any defective cannot be
found, check the wiper relay (LOW) for defective. 1.
2.
3.If the installed wiper brushes are out of specification (size and length), the rain sensing area
cannot be fully wiped. In this case, the rain sensor’s sensitivity could be decreased and
the wipers are not properly operated. - The followings are the detailed description of the functions and operations of the rain sensing wiper
control.
As described, the STICS recognizes the wiper switch “AUTO” position. If there are not any
problem, go to diagnosis mode in STICS and check the terminal that receives signal from wiper
and communication lines between rain sensor unit and STICS. -
When the variable resistance knob is rotated by 4 stage from 0 stage without stopping, the wiper
operates one cycle. The wiper operates one cycle when changing the wiping stage (0 →
1, 1 → 2, 2 → 3). -

4) Washer Coupled Wiper Function
Check the washer coupled wiper operation by pressing the washer switch.
5) Irregular Operations (Abrupt Operations)
6) Self Diagnosis
Position the wiper switch to “AUTO” position and rotate the variable resistance knob from
“FAST” toward “SLOW” by one step.
At this moment, check if the wiper operates one cycle.
The wiper operates when the windshield glass is excessively worn or scratched, the windshield glass is
not cleared wiped due to using worn wiper blade or different wiper blade, or the rain sensor is not
improperly installed.Check the sensor for coming off.
Check the rain sensor cover installation.
Check that the customer is familiar to how to control the wiper sensitivity. -
-
-
If the wiper blade cannot wipe the glass uniformly and clearly, the irregular operations could be
occurred. And, the wiper blade should be replaced with new one with same specifications. Check that the customer can select the sensitivity by selecting the variable resistance value (stage 1 to
stage 5), that is, the wiper sensitivity control value. And, also check whether the sensitivity is selected
to the highest value of FAST (stage 5).
Check the wiper blade for wear. -
▶Poor sensing
▶Poor sensor
Rotate the variable resistance knob toward “SLOW” by 2 more steps. At this moment, check if
the wiper operates one cycle.
The wiper operates when the sensor is defective.

6. RAIN SENSOR RELATED CIRCUIT
The rain sensor has one connector with 4 pins and each pin has following function as shown in the
circuit diagram.
However, in this vehicle, the terminal No. 1 and No. 2 are for communications between STICS and the
rain sensor; the No. 1 terminal sends the detected value from the rain sensor to STICS then the STICS
drives wiper motor.
to the rain sensor to recognize whether it is actual rain or it is in rain sensing wiper operation mode.
No.2 terminal sends the wiper and washer operation information such as
washer operation mode,
MIST mode, or
AUTO wiper position -
