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.
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 pro
operated
2) Recognition of AUTO Mode
1) 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.
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.
As described, the STICS recognizes the wiper switch "AUTO" position. If there are not a
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.
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.
