Compressor Clutch: Description and Operation

The ECM (ECCS control module) controls compressor operation using inputs from the throttle position sensor and auto amplifier.

Low Temperature Protection Control:

The auto amplifier will tell the ECM (ECCS Control Module) to turn the compressor ON or OFF. This signal is based on input from the ambient temperature sensor.

Acceleration Cut Control
The ECM (ECCS Control Module) will turn the compressor ON or OFF based on the signal from the throttle position sensor.
