NOTE:
Both the Medium Speed Controller Area Network (MS-CAN) and the High Speed Controller Area Network (HS-CAN) are used for intermeddle communication. A gateway message is transferred from one network to another network through the IPC. Refer to
MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ
article for network communication information.
