6. FUNCTIONS AND CHECKS OF RAIN SENSOR

Front Windshield Glass and Coupler Attachment
Check the outer windshield surface of sensing area for wear, damage and scratch. The sensor is able to compen-
sate 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.
NOTE
• 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.
Recognition of AUTO Mode
1. When the engine is started with the multifunction wiper switch "AUTO" position, the wiper operates one cycle to
remind a driver that the wiper switch is in "AUTO" position.
2. When the wiper 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.
3. 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.
NOTE
• 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.
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.
NOTE
• When the variable resistance knob is rotated by 4 stage from 0 stage without stoping, the wiper operates one
cycle. The wiper operates one cycle when changing the wiping stage (0 → → → → → 1, 1 → → → → → 2, 2 → → → → → 3).
