Control System Logic

The EMTC system customer interface is in one or more locations depending on vehicle option content:

When the customer directly inputs an A/C request into the FCIM, the module sends the request to the GWM over the MS-CAN, and the GWM sends the request to the PCM over the HS-CAN1.

When the touchscreen FDIM or voice commands are used, and A/C is selected, the APIM sends the request message over the HS-CAN3 to the GWM. The GWM sends the message to the FCIM over the MS-CAN and the GWM sends the A/C request to the PCM over the HS-CAN1.

The FCIM requires PMI when it is replaced.
