Principles of Operation: Notes
The vehicle has 2 module communication networks which are connected to the Data Link Connector (DLC), located under the instrument panel.
Both the High Speed Controller Area Network (HS-CAN) and Medium Speed Controller Area Network (MS-CAN) use an unshielded twisted-pair cable of data (+) and data (-) circuits. The HS-CAN operates at a maximum data transfer speed of 500 Kbps and is designed for real time information transfer and control. The MS-CAN operates at a maximum data transfer speed of 125 Kbps for bus messages and is designed for general information transfer.
The Infotainment Controller Area Network (I-CAN) is not connected to the Data Link Connector (DLC), but the I-CAN modules communicate with the scan tool over the High Speed Controller Area Network (HS-CAN). The Instrument Panel Cluster (IPC) is used as a gateway for the messages to transfer between the scan tool and the modules on the I-CAN.
