SYSTEM DESCRIPTION
The front air control controls compressor operation based on ambient and intake temperature and a signal from ECM.




Low Temperature Protection Control
The front air control will turn the compressor ON or OFF as determined by a signal detected by the intake sensor and the ambient sensor.

When intake air temperature is higher than the preset value, the compressor turns ON. The compressor turns OFF when intake air temperature is lower than the preset value. That preset value is dependent on the ambient temperature, refer to the table.
