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 (Smark) 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 wi
per switch “AUTO” position, the wiper operates one cycle

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.

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 stoping, the
wiper operates one cycle. The wiper operates one cycle when changing the wiping stage (0
→ 1, 1 → 2, 2 → 3). -
