AUTOMATIC AIR CONDITIONER SYSTEM

MODE CONTROL DIAL

Controls the air discharge outlets.
Positions the air outlet doors to the defrost position. Also positions the intake doors to the outside air position.
When shifting mode control dial to DEF under the following conditions, compressor is turned ON. (A/C LED
ON)
• BLOWER: ON
• A/C: OFF

TEMPERATURE CONTROL DIAL (POTENTIO TEMPERATURE CONTROL)

Increase or decrease the set temperature.

BLOWER CONTROL DIAL

Automatically or manually control the blower speed. Seven speeds are available for manual control.
Shifting blower control dial to AUTO, compressor is turned ON automatically.

REAR WINDOW DEFOGGER SWITCH

When illumination is ON, rear window is defogged.

A/C SWITCH

The compressor is ON or OFF.
(Pressing the A/C switch when the blower control dial is ON will turn off the A/C switch and compressor.) 

INTAKE SWITCH

• When intake switch is ON, REC indicator turns ON, and air inlet is fixed to REC.
• When press intake switch again, FRE indicator turns ON, and air inlet is fixed to FRE.
• When DEF position or FRE indicator is turned ON, or when compressor is turned from ON to OFF, REC

switch is automatically turned OFF (fixed to FRE mode).
REC mode can be re-entered by pressing intake switch again. (Except DEF position)

MAGNET CLUTCH CONTROL

When mode control dial and blower control dial is turned to AUTO position, AUTO switch or DEF switch is
pressed, front air control inputs compressor ON signal to BCM.
BCM sends compressor ON signal to ECM, via CAN communication line.
ECM judges whether compressor can be turned ON, based on each sensor status (refrigerant-pressure sen-
sor signal, throttle angle, etc.). If it judges compressor can be turned ON, it sends compressor ON signal to
IPDM E/R, via CAN communication line.
Upon receipt of compressor ON signal from ECM, IPDM E/R turns air conditioner relay ON to operate com-
pressor.
