[MANUAL AIR CONDITIONER]

AIR CONDITIONER CONTROL

ECM judges whether compressor can be turned ON, based on each sensor status (refrigerant pressure sen-

sor signal, throttle angle sensor, etc.). If it judges compressor can be turned ON, it sends compressor ON sig-

nal 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.
