Control System Logic

WARNING: This page is about a different car, the 2017 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

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.
