RAIN SENSOR
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 -
