Compressor Magnetic Clutch Circuit

COMPRESSOR MAGNETIC CLUTCH CIRCUIT

CIRCUIT DESCRIPTION

The A/C amplifier outputs the magnetic clutch ON signal from terminal A/CS to the ECM. When the ECM receives this signal, it sends a signal from terminal ACMG and switches the A/C magnetic clutch relay ON, thus turning on the A/C magnetic clutch.
