Nissan Murano: Dtc/circuit Diagnosis / U1000 Can Comm Circuit

DTC Description

DESCRIPTION

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-Nissan Murano vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a Nissan Murano vehicle, and each control unit shares information and links with other control units during operation (not independently). In CAN communication, control units are connected with two communication lines (CAN-High, CAN-Low), allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
