U1000 CAN COMM CIRCUIT
Description
INFOID:0000000009886105
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 independent). 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.
