Compressor Clutch: Description and Operation
CIRCUIT DESCRIPTION
The A/C ECU (Combination meter ECU) 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 the A/C compressor magnetic clutch ON.
