▶Auto Switch Position Reminder (Power-Up Reminder Wiper)
When turning off and on the IGN2 switch with the auto switch on, the system drives
the wiper motor through LOW relay one cycle regardless of communication with rain
sensor.
The wiper relay (LOW) is turned on and the wiper motor runs one cycle when
changing the auto switch from “OFF” to “ON” position regardless of
communication with rain sensor(while the ignition key is in the “ON” position).
When the auto switch is turned to the “ON” position again from the “OFF”
position, the system drives the wiper motor through LOW relay one cycle only when
the rain sensor detects the “Rain Detected” signal.

▶Washer Coupled Wiper in Rain Sensing Mode
The washer coupled wiper is operated when receiving the washer switch input with
the ignition switch “ON” and the AUTO switch “ON” in the rain sensing mode.
At this moment, the communication with the rain sensor is overridden. However, the
washer switch input is overridden during the continuous operation.
The operation data is sent to the rain sensor even during the washer coupled wi
er’s
operation

▶Rain Sensing Sensitivity Control
The wiper LOW relay is turned on and the wiper motor runs one cycle when the
volume sensitivity is increased (while the ignition key is in the “ON” position, the
AUTO 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 senso
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 wipe
parking terminal is grounded (while the ignition key is in “ON” position and the
AUTO 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 HIGH with the ignition key and the AUTO switch
in “ON” position, 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 AUTO 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 AUTO switch is
in “ON” position).
