TROUBLE SHOOTING
Symptom 1.
The wiper does not operate one cycle when turning the multifunction
wiper switch to the "AUTO" from the "OFF" position or starting the engine
while the wiper switch is in the "AUTO" position.
1)
When starting the engine with the multifunction wiper switch in the "AUTO" position,
the wiper operates one cycle to remind a driver that the wiper switch is in the "AUTO"
position.
2)
When the multifunction 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. If this function does not occur, check No. 8 pin. If the pin is normal,
check the wiper relay related terminals.
Symptom 2. It rains but the system does not work in "AUTO" position.
1)
Check whether the multifunction wiper switch is in the "AUTO" position.
2)
Check the power to the sensor. Check the conditions of the pin 3 (Ground) and the pin
4 (IGN).
3)
Check the wiper relay for defective.
Symptom 3. The wiper operates 3 or 4 times at high speed abruptly.
Check whether the variable resistance knob on the multifunction wiper switch is set in
"FAST". The "FAST" is the highest stage of sensitivity and very sensitive to small amount
of rain drops. Therefore, change the knob to low sensitivity.
Symptom 4. The wiper operates continuoulsy even on the dry windshield glass.
1)
Check the wiper blade for wear. If the wiper blade cannot wipe the glass uniformly
and clearly, this problem could be occurred. In this case, replace the wiper blade
with new one.
2)
Check whether the variable resistance knob on the multifunction wiper switch is set
in "FAST" The "FAST" is the highest stage of sensitivity and very sensitive to small
amount of rain drops. Therefore, change the knob to low sensitivity.
