A/C Compressor Control Module (A/C Relay)

A/C Cutout Signal
The powertrain control module (PCM) can prevent the engagement of the A/C compressor clutch through the A/C compressor control module. The PCM provides a ground signal to the A/C compressor control module that enables the A/C compressor control module to operate the A/C compressor clutch relay.
The PCM allows the A/C compressor clutch to operate at customer request except during wide open throttle engine operation.
