U1000 CAN COMM CIRCUIT

Description

INFOID:0000000005258955

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-

tiplex communication line with high data communication speed and excellent error detection ability. Modern

vehicle is equipped with many electronic control unit, 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.
