U1000 CAN COMM CIRCUIT

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000012201321

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 detectability. 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 connected

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.

CAN Communication Signal Chart. Refer to 

LAN-30, "CAN COMMUNICATION SYSTEM : CAN Communica-

tion Signal Chart"
