Compressor Clutch: Description and Operation
The ECM (ECCS control module) controls compressor operationusing inputs from the throttle position sensor and auto amplifier.
Low temperature protection control
Auto amplifier will turn the compressor "ON" or "OFF" as determined by a signal detected by ambient temperature sensor. The compressor turns "OFF" when ambient temperatures are less than -1 °C (30 °F).
Acceleration cut control
The ECM (ECCS control module) will turn the compressor "ON" or "OFF" based on the signal from the throttle position sensor.
