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.

Compressor Solenoid Circuit (B1451/51)
DESCRIPTION
In this circuit, the A/C compressor receives a refrigerant compression demand
signal from the A/C amplifier.
Based on this signal, the A/C compressor changes the amount of compressor output.
