CAN COMMUNICATION: System Description: Description

WARNING: This page is about a different car, the 2013 Nissan Leaf. However, it is still accessible from the selected car via links, so may be relevant.

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
VCM includes a gateway function and communicates signals between the CAN communication circuit and EV system CAN circuit.
