CAN COMMUNICATION EC-495 < SYSTEM DESCRIPTION > [VQ40DE FOR USA AND CANADA] C D E F G H I J K L M A EC N P O CAN COMMUNICATION System Description INFOID:0000000009481196 CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul- tiplex communication line with high data communication speed and excellent error detection ability. Many elec- tronic 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. LAN-53, "CAN System Specification Chart" , about CAN communication for detail. |
