DTC/CIRCUIT DIAGNOSIS
U1000 CAN COMM CIRCUIT
Description
INFOID:0000000012200036
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-board mul-
tiplex communication line with high data communication speed and excellent error detection ability. A modern
vehicle is equipped with many ECMs, and each control unit shares information and links with other control
units during operation (not independent). In CAN communication, 2 control units are connected with 2 commu-
nication lines (CAN-L line and CAN-H line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
