DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000009471622

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

vehicles are equipped with many electronic control units, and each control unit shares information and links

with other control units during operation (not independent). In CAN communication, control units are con-

nected 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 selectively reads required data only.
