Sub-Cool A/C System DescriptionS7RS0B7211003
In the sub-cool A/C system (condenser integrated with receiver/dryer), the inside of the condenser is divided into the
condensation part and the sub-cooler part, and the receiver/dryer is located between those. In the receiver/dryer, the
refrigerant is separated into the vapor refrigerant and the liqui d refrigerant. Only the liquid refrigerant is delivered to the
sub-cooler part of the condenser. The refrigerant is supercooled by the sub-cooler part of the condenser.
A/C Operation DescriptionS7RS0B7211004
ECM controls the radiator fan relay and the compressor relay by following signals.
• ON/OFF signal of A/C switch
• A/C refrigerant pressure sensor
• Evaporator thermistor (evaporator temperature sensor)
• ECT sensor
NOTE
The signal of A/C swit ch is fed from BCM to ECM usin g CAN communication system. For CAN
communication system, refer to “CAN Communication System Description in Section 1A”.
