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.
