Control System Logic

When the customer directly inputs an A/C  request into the FCIM  , the module sends the request to the GWM  over the Medium Speed Controller Area Network (MS-CAN). The GWM  sends the request to the PCM  over the High Speed Controller Area Network (HS-CAN). The PCM  controls the A/C  clutch relay.
