SYSTEM DESCRIPTION
Hydraulic Circuit Diagram
INFOID:0000000001327663
CAN CommunicationINFOID:0000000001327664
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application.It is an on-vehicle multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and eac h control unit shares information and kinks with other
control units during operation (not independent). In CA N communication, control units are connected with 2
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 se lectively reads required data only. Refer to LAN-43, "
CAN Sys-
tem Specification Chart".
