Compressor Circuit

Compressor Circuit

CIRCUIT DESCRIPTION
The A/C control assembly outputs the magnetic clutch ON signal from terminal MGC 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 compressor magnetic clutch.

The A/C control assembly also monitors at terminal A/C IN whether or not power is being supplied to the magnetic clutch.
