U1000 CAN COMM CIRCUIT
Description
INFOID:0000000011276687
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped onto vehicles, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with two 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. Refer to
LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"
.
