U1000 CAN COMM CIRCUIT

U1000 CAN COMM CIRCUIT

AV CONTROL UNIT
AV CONTROL UNIT : Description

INFOID:0000000010122654

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

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

vehicle is equipped with many ECMs, 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 H-line and 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-37, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"

 for details of the

communication signal.

AROUND VIEW MONITOR CONTROL UNIT : Description

INFOID:0000000010122657

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

tiplex communication line with high data communication speed and excellent error detection ability. Many elec-

tronic control units are equipped onto a vehicle, and each control unit shares information and links with other

control units during operation (not independently). In CAN communication, 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.
