COMPRESSOR CIRCUIT

CIRCUIT DESCRIPTION
The ECM and A/C amplifier communicate via BEAN.

The A/C amplifier assy outputs the magnetic clutch ON signal to the ECM.
Receiving this signal, the ECM sends a signal through terminal ACMG and switches the magnetic clutch relay ON, thus turning on the magnetic clutch.
