U1000 CAN COMM CIRCUIT
Descr iptionINFOID:0 000000005146905
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
v ehicle is equipped with many ele ct ronic control uni t, and each control unit shares information and links with
other control units during operation (not independent). In CAN communicat ion, control units are connected
wi
th 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of inf ormation transmission with less
wiring
. Each control unit transmits/receives data but selectively reads required data only.
