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 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)

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.

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). -

3) To Activate Driver & Front Passenger Seat Warmer
Operating condition ▶
Turn the ignition key to the "ON" position and start the engine.
If the cranking signal is inputted, the seat warmer stops working during cranking.
Operation description ▶
When pressing the seat warmer switch for the driver and/or front passenger seat with IGN ON, the
seat warmer operates. Press the switch again to stop the seat warmer.
Operation procedures ▶
When pressing the seat warmer switch for the driver and/or front passenger seat, the seat warmer
relay in the ICM box is activated to supply power to the seat warmer.

The driver and front passenger seat warmers have separate circuits, allowing them to function
independently.
