Nissan Murano: Dtc/circuit Diagnosis / U1000-01 Can Comm Circuit
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-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

Vehicle security system
Your vehicle has two types of security systems:
Vehicle security system NISSAN Vehicle Immobilizer SystemThe vehicle security system provides visual and audible alarm signals if someone opens the doors, liftgate or the hood when the system is armed. It is not, however, a motion detection type system that activates when a vehicle is moved or when a vibration occurs.
