362Air Conditioning (Front)
1. Heater Blower Operation
Manual operation
When the blower speed is set ant any speed by the blower control SW, the A/C control assembly sends a signal to the
blower motor controller, and controls the blower motor speed.
Auto operation
When the auto SW is operated, the A/C control assembly sends signals to the blower motor controller, according to the
signals from respective sensors, commands from the temperature SW etc., and controls the blower motor automatically.
2. Air Inlet Control Servo Motor Control
When the FRESH/RECIRC select SW is switched to RECIRC, the motor in the air inlet control servo motor rotates to move
the damper to the RECIRC side. The damper position is recognized by the A/C control assembly TERMINAL TPI, and
rotates the motor until the damper reaches its position.
When the FRESH/RECIRC select SW is switched to FRESH, the motor in the air inlet control servo motor rotates to move
the damper to the FRESH side. The damper position is recognized by the A/C control assembly TERMINAL TPI, and rotates
the motor until the damper reaches its position.
When the FRESH/RECIRC select SW is set to auto, the exhaust gas sensor in the engine room detects the ingredient of the
exhaust emission, and switches the FRESH/RECIRC mode automatically.
3. Air Vent Mode Control Servo Motor
When the mode select SW in the A/C control assembly is pushed, a signal is sent from the A/C control assembly, and
activates the air vent mode control servo motor. This causes the servo motor to rotate to the position selected using the
mode select SW (FACE, BI-LEVEL, FOOT, FOOT/DEF, DEF), and moves the damper.
4. Air Mix Control Servo Motor
When the temperature control SW in the A/C control assembly is pushed, a signal is sent from the A/C control assembly, and
activates the air mix control servo motor. The motor and damper is moved until it reaches the temperature set by the
temperature control SW.
5. Air Conditioning Operation
The A/C control assembly receives various signals, i. e., the engine RPM from the crankshaft position sensor, outlet
temperature from the A/C ambient temp. sensor, coolant temperature from the engine coolant temp. sensor, and the lock
signal from the A/C compressor, etc. When the engine is started and the A/C SW is turned on, a signal is sent to the A/C
control assembly. As a result, the magnetic clutch is turned on and operates the compressor.
In addition, when the engine control module detects that the magnetic clutch is on and the A/C compressor is operating, it
controls the engine in the direction to avoid lowering the engine RPM during A/C operation.
When any of the following signals are sent to the A/C control assembly, the A/C is turned off.
*Coolant temp. is high.
*Outlet air temp. is low.
*Large difference between the engine speed and compressor speed.
*The refrigerant pressure is abnormally high or low.

1. Cooler and Heater Blower Operation
*Manual operation
When the blower control SW in the rear A/C control SW is set to any blower speed, a signal is sent to the A/C amplifier.
The A/C amplifier controls the power transistor and operates the rear cooler blower motor and rear heater blower motor at
the set speed.
*Auto operation
When the auto SW in the rear A/C control SW is operated, a signal is sent to the A/C amplifier. The A/C amplifier controls
the power transistor according to the signals from respective sensors, and operates the rear cooler blower motor and rear
heater blower motor.
2. Air Mix Control Servo Motor Control
When the temperature control lever in the rear A/C control SW is operated, a signal is sent to the A/C amplifier. The A/C
amplifier controls the rear air mix control servo motor to operate the damper until it reaches the temperature set by the
temperature control lever.
3. Air Conditioning Operation
The cooler and heater operation can be switched by the mode select SW in the rear A/C control SW.
