Control System Logic (Hybrid)

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

• Front Controls Interface Control Module B (FCIM-B)
• Touchscreen FDIM (part of APIM)

When the FDIM touchscreen or voice commands are used and A/C is selected, the APIM sends the request message over the HS-CAN3 to the GWM. When the customer inputs an A/C request into the Front Controls Interface Control Module B (FCIM-B), the module sends the request to the GWM over the HS-CAN3. Once the A/C request is selected from either interface, the GWM sends the request to the SOBDMC over the HS-CAN1. The SOBDMC controls the electric compressor. The GWM also sends the request to the HVAC control module over the MS-CAN.
