Control System Logic

The climate control system controls are in one or more locations depending on vehicle option content:

When the FDIM touchscreen or voice commands are used and A/C is selected, the APIM sends a function request message over the Infotainment Controller Area Network (I-CAN) to the IPC. The IPC relays the requests to the GWM and the FCIM over the MS-CAN. The GWM sends the requests to the PCM over the HS-CAN. The PCM controls the A/C clutch relay.

When the customer directly inputs an A/C request into the FCIM, the module sends the request to the GWM over the MS-CAN. The GWM sends the request to the PCM over the HS-CAN. The PCM controls the A/C clutch relay.

The FCIM Programmable Module Installation (PMI) when it is replaced.
