SYSTEM DESCRIPTION
The ECM sends the engine speed signal to the A/C amplifier via CAN communication.
The A/C amplifier reads the difference between compressor speed and engine speed. When the difference becomes too large, the A/C amplifier determines that the compressor is locked, and turns the magnetic clutch off.
