AIR CONDITIONING
5. AIR CONDITIONING OPERATION
THE A/C AMPLIFIER RECEIVES VARIOUS SIGNALS, I.E., THE ENGINE RPM FROM THE IGNITER, OUTLET
TEMPERATURE SIGNAL FROM THE A/C THERMISTOR, 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 (HEATER CONTROL SW) IS ON, A SIGNAL IS INPUT TO THE A/C
AMPLIFIER. AS A RESULT, THE GROUND CIRCUIT IN A/C AMPLIFIER IS CLOSED AND CURRENT FLOWS FROM HTR
FUSE TO TERMINAL 1 OF THE A/C MAGNETIC CLUTCH RELAY  TERMINAL 2 TERMINAL ACMG OF THE ENGINE
CONTROL MODULE TERMINAL A/C TERMINAL MGC OF THE A/C AMPLIFIER TERMINAL GND 
GROUND, TURNING THE RELAY ON, SO THAT THE A/C MAGNETIC CLUTCH IS ON AND THE A/C AMPLIFIER
OPERATES.
AT THE SAME TIME, THE ENGINE CONTROL MODULE DETECTS THE MAGNETIC CLUTCH IS ON AND THE A/C
AMPLIFIER IS OPERATING AND OPENS DIRECTION TO AVOID LOWERING THE ENGINE RPM DURING A/C
OPERATING.
WHEN ANY OF THE FOLLOWING SIGNALS ARE INPUT TO THE A/C AMPLIFIER, THE A/C AMPLIFIER OPERATES TO
TURN OFF THE AIR CONDITIONING.
*ENGINE RPM SIGNAL IS HIGH.
*COOLANT TEMP. SIGNAL IS HIGH.
*A SIGNAL THAT THE TEMPERATURE AT THE AIR OUTLET IS LOW.
*A SIGNAL THAT THERE IS A LARGE DIFFERENCE BETWEEN ENGINE SPEED AND COMPRESSOR SPEED.
*A SIGNAL THAT THE REFRIGERANT PRESSURE IS ABNORMALLY HIGH OR LOW.
