5) Shutting-off Condition of the A/C Compressor
Coolant temperature ▶
When coolant temperature is below 20°C or over 115°C, engine speed is below 650 rpm or
over 4500 rpm for 4 seconds after engine starting, abrupt acceleration and A/C refrigerant
pressure sensor detecting the followings
A/C compressor is turned off when the refrigerant pressure is below 2.0 kg/cm2 and then
is turned on when the refrigerant pressure is over 2.4 kg/cm2.
A/C compressor is turned off when the refrigerant pressure is over 30 kg/cm2 and then is
turned on when the refrigerant pressure is below 21.4 kg/cm2. -

The auto washer switch input is overridden during the washer coupled wiper operation.
The auto washer switch input is overridden during the auto washer coupled wiper
operation.
The auto washer switch input is overridden during the rain sensor coupled wiper or vehicle
speed sensitive INT wiper operation.
When the auto INT switch input is received during the auto washer operation, the auto
washer operation stops and the auto INT operation is activated. -

▶Rain Sensor Coupled Wiper and Auto Light Control
If equipped with RKSTICS rain sensor, it has following operation system. -
▶System layout

02-138710-01
Rain sensing unit
(AUTO light integrated type)
▶INT Switch Auto Position Reminder (Power-Up Reminder Wiper)
When turning off and on the auto INT switch, the system drives the wiper motor through
LOW relay regardless of communication with rain sensor.
When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition switch
in the "ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle, regardless
of the rain sensor communication.
After that, when turning the INT-AUTO switch from the "OFF" to "ON" position, the LO
W
relay operates to drive the wiper motor for 1 cycle only if data from the rain sensor
indicates rain drops. -

Multifunction wiper switch:
AUTO and sensitivity control
A sensor that emits infrared rays through LED
and then detects the amount of rain drops by
receiving reflected rays against sensing section
(rain sensor mounting section on the
windshield) with photodiode (auto light sensor
integrated type)AUTO: Wiper operates automatically by rain
sensor
FAST↔SLOW: Auto delay/Auto speed control. A
position that can control sensitivity against rains
on the windshield and transmits wiping demand
signal accordingly

▶Washer Coupled Wiper in Rain Sensing Mode
The washer coupled wiper is operated when receiving the washer switch input with the
ignition switch and the INT-AUTO switch "ON" in the rain sensing mode. At this moment,
the communication with the rain sensor is overridden. However, a washer input is overridden
if there is an output for continuous operation.
The operation data is sent to the rain sensor even during the washer coupled wiper's
operation. -

▶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. -
