▶Sensitivity Control

The wiper LOW relay is turned on and the wiper motor runs one cycle when the volume sensitivity 

is increased (ex: sensitivity 0 ⇒  1) while the ignition  switch and the INT switch is in the "ON" 

position, and the wiper motor is in "Parked" position). However, the wiper motor can be operated 

only when the rain sensor detects the "Rain Detected" signal.

If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs 

only one cycle.

▶When the Wiper Parking Signal is abnormal

The wiper system continuously outputs the wiper parking signal when the wiper parking terminal 

is grounded, while the ignition switch is in "ON" position and the INT switch is in "ON" position.

-

※The wiper motor runs only when the rain sensor requires the wiper operation.

When the parking terminal is fixed to IGN, the wiper system outputs the wiper operating signal 

for 2 seconds, then continuously outputs the wiper parking signal.

-

※The wiper motor runs only when the rain sensor requires the wiper operation.

▶Defective Rain Sensor

The wiper relay (LOW) is turned on and the wiper motor runs one cycle when the volume 

sensitivity is changed to 2 from 3 during receiving the malfunction signal from the rain sensor, 

while the ignition key is in "ON" position and the wiper switch is in "ON" position.

-

The wiper relay (LOW) is turned on and the wiper motor runs one cycle when the volume 

sensitivity is changed to 3 from 4 during receiving the malfunction signal from the rain sensor, 

while the ignition key is in "ON" position and the wiper switch is in "ON" position.

Check whether the multifunction wiper switch is in the "AUTO" position.

Check the power to the sensor. Check the conditions of the pin 3 (Ground) and the pin 4 

(IGN).

Check the wiper relay for defective.

Symptom 2. It rains but the system does not work in "AUTO" position.

TROUBLE SHOOTING

▶

The wiper does not operate one cy cle 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.

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.

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 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.

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. 

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.
