U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000001728646
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN 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 selectively reads required data only.

Part name Description
NAVI CONTORL UNIT Map data can be read from the map DVD-ROM by installing map DVD-ROM.
 It is the master unit of the MULTI AV system, and it is connected to each control
unit by means of communication. It operates each system according to com-
munication signals from the NAVI control unit.
 The NAVI control unit includes the audio, hands-free phone, navigation, and
vehicle information functions.
 It is connected to ECM and combination meter via CAN communication to ob-
tain necessary information for the vehicle information function.
 It inputs the illumination signals that are required for the display dimming con-
trol.
 It inputs the signals for driving status recognition (vehicle speed, reverse and
parking brake).
