U1000 CAN COMM CIRCUIT

CAN (Controller Area Network) is a serial communication line for real‐time application. It is an on board multiplex communication line with high data communication speed and excellent error detection ability. A modem vehicles are equipped with many ECUs, and each control unit shares information and links with other control units during operation (not independently). In CAN communication, 2 control units are connected with 2 communication lines (CAN‐H, CAN‐L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
