Control System Logic (Hybrid)

When the customer inputs an A/C request into the information and entertainment display unit or by voice command, the APIM sends the request to the GWM over the HS-CAN3 (high-speed controller area network 3) If the A/C request is inputted through the HVAC manual control head the request is sent to the GWM over the MS-CAN. The GWM relays the request to the SOBDMC over the FD-CAN (Flexible Data Rate Controller Area Network), and the request message is sent to the ACCM electric compressor over the HS-CAN1 (high-speed controller area network 1).

For a list of all the network messages. Refer to: Controller Area Network (CAN) Module Communications Network - System Operation and Component Description .
