U1000 CAN COMM CIRCUIT

Description

INFOID:0000000012202623

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

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

vehicle is equipped with many ECUs, and each control unit shares information and links with other control

units during operation (not independent). In CAN communication, 2 control units are connected with 2 commu-

nication lines (CAN-L-line and CAN-H-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-30, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"

 for details of the

communication signal.
