SYSTEM DESCRIPTION
The ECM sends the engine speed signal to the air conditioning amplifier assembly via CAN communication.
The air conditioning amplifier assembly reads the difference between compressor speed and engine speed. When the difference becomes too large, the air conditioning amplifier assembly determines that the compressor is locked, and turns the magnet-clutch assembly off.
