Air Conditioning Clutch On Signal

AIR CONDITIONING CLUTCH "ON" SIGNAL

CIRCUIT DESCRIPTION

The air conditioning 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 air conditioning magnetic clutch relay on, thus turning on the air conditioning compressor magnetic clutch. The air conditioning control assembly also monitors at terminal NC IN whether or not power is being supplied to the magnetic clutch.
