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.
