AC–62
AIR CONDITIONING SYSTEM – TROUBLESHOOTING
Compressor Circuit
CIRCUIT DESCRIPTION
The A/C amplifier 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 the air conditioning compressor magnetic clutch ON.
