(2) FUNCTIONS OF RAIN SENSOR
A. 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.
B. Recognition of AUTO mode
- When the engine is started with the wiper switch "AUTO"
operates one cycle to remind a driver that the wiper switch is in "AUTO"
- When the wiper switch is turned to "AUTO"
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.
C. 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.
(3) WASHER COUPLED WIPER FUNCTION
Check the washer coupled wiper operation by pressing the washer switch.
(4) IRREGULAR OPERATIONS (ABRUPT OPERATIONS)
- 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.
- 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.
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.

(5) SELF DIAGNOSIS
A. Poor sensing
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.
B. Poor sensor
Rotate the variable resistance knob toward "SLOW"
check if the wiper operatesone cycle.
The wiper operates when the sensor is defective.
