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 2 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.
