Auto washer coupled wiper ▶
When turning ON the auto washer switch with IGN ON and intermittent/automatic wiper switch OFF,
the washer fluid is sprayed onto the windshield glass for 2 seconds and the wipers operate 4 times.
After then, additionally, the washer fluid is sprayed for 1.5 seconds and the wipers operate 3 times
again.
The auto washer switch signal is overridden during speed sensitive intermittent wiper, washer
coupled wiper or auto washer coupled wiper operation.
When turning the wiper switch to AUTO position during the operation of auto washer, the auto
washer stops its operation and the intermittent/automatic wiping mode will be started.
The front and rear washer switch signal are overridden during the operation of auto washer. 1.

Rain sensor coupled wiper (LIN) ▶
System layout 1.
Data recognition & operation 2.
Data recognition time
The system performs LIN communication regardless of the conditions of wiper and light switch when
the ignition switch is in ON position. If the intermittent/automatic wiper switch is in "AUTO" and the
light switch is in "AUTO" position, the wiper system operates according to the LIN data.
The data received from the rain sensor is recognized for 2 times consecutively.
Operation when recognizing data
No data: wiper low/high relay OFF
Low speed signal: low relay ON (ON for at least one cycle), but high relay OFF
High speed signal: high relay ON (ON for at least one cycle), but low relay OFF
The washer switch signal is overridden during continuous operation of the wiper.
(Washer coupled wiper function is available only during intermittent operation) -

Power-up reminder wiper ▶
If the intermittent/automatic wiper switch is in "ON" position, the wiper motor does not operate even
when turning the ignition switch to ON from OFF position.
When turning the intermittent/automatic wiper switch to ON from OFF position with IGN ON, the wipers
operate once at low speed initially regardless of the communication with the rain sensor. After that, the
wipers operate once at low speed only when the rain sensor detects
the side fascia panel. 1.

Washer coupled wiper in rain sensing mode ▶
When the washer switch signal is received during intermittent operation coupled with rain sensor
with IGN ON and intermittent/automatic washer switch operation, the wipers operate in washer
coupled mode regardless of the communication with the rain sensor. However, if the washer switch
signal is received the washer relay is activated and wiper relay remains activated, when the data
coupled with rain sensor indicates continuous wiper operation.
Even though the wiping system is in washer coupled wiper mode, the operating data are sent to rain
sensor. 1.

Sensitivity adjustment (instant wiping) ▶
When the wiping speed control switch is turned to "FAST" with IGN2 ON, intermittent/automatic wiper
switch in "ON" position and wiper motor stop (parking position), the wiper motor operates one cycle at
low speed.
(only when the rain sensor detects raindrops)
If the wiping speed control switch is changed more than 2 stages within 2 seconds, the wiper motor
operates only one cycle. 1.

Processing method for abnormal wiper parking signal ▶
The wiper system sends continuously the signal for current status when the wiper parking terminal is
shorted to ground with IGN2 ON and intermittent wiper switch in "ON" position.
The wiper motor runs only when the rain sensor requires the wiper operation. 1.*
When the parking terminal is shorted to power with IGN2 ON and intermittent wiper switch in "ON"
position, the wiper system sends the signal for current wiping status for 2 seconds. After that, it sends
the current signal for parking status continuously.
The wiper motor runs only when the rain sensor requires the wiper operation. 2.*

Processing method for rain sensor malfunction ▶
If the BCM is received the signal for sensor malfunction from the rain sensor unit when turning the
wiping speed control switch to 2 from 3 stage with IGN ON and intermittent/automatic wiper switch in
"ON" position, the wiper motor operates one cycle at low speed. 1.
If the BCM is received the signal for communication error from the rain sensor unit when turning the
wiping speed control switch to 3 from 4 stage with IGN ON and intermittent/automatic wiper switch in
"ON" position, the wiper motor operates one cycle at low speed. 2.

Speed sensitive intermittent wiper ▶
The BCM without rain sensor operates the wiper as follows:
When turning the ignition switch to ON from OFF position with the intermittent wiper switch in "ON"
position, the wipers do not operate.
When turning the wiper switch to ON from OFF position after turning the ignition switch to ON position,
the wipers operate one cycle.
The wiper's operation cycle depends on the vehicle speed (CAN communication with instrument
cluster) and wiping speed the side fascia panel.

Wiper low/high control ▶
The wiper low relay is activated when the wiper low switch is operated and the wiper high relay
activated when the wiper high switch is operated.
The wiper motor returns to parking position and stops, even when turning off the ignition switch during
wiper operation.
The wiper relay should remain activated during wiper operation in low/high mode even though the
system does not receive P-POS signal. (During intermittent/automatic wiper operation, the wiper relay
should be deactivated after 5 seconds if there is no P-POS signal for 3 seconds in order to inform the
driver of faulty signal)
While the wiper operates at low/high speed, the front/rear washer switch can be operated but the auto
washer switch cannot.
The wiper motor returns to parking position and stops when turning off the ignition switch during wiper
operation in high mode. 1.
