Nissan Murano: Side Radar (rear Right) (side Radar Rh) / U1000-01 Can Comm Circuit
DESCRIPTION
CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication line for real-time applications. It is an on-Nissan Murano vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern Nissan Murano vehicles are equipped with many electronic control units, 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, CAN-L), allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads the required data only.
For CAN communication signal chart. Refer to CAN Communication Signal Chart.
ITS COMMUNICATION
-
ITS communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed by connecting plural units with 2 communication lines.
-
ITS communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.

Driver and passenger supplemental knee air bag
Driver’s side
The knee air bag is located in the knee bolster, on the driver’s and passenger’s side. All of the information, cautions and warnings in this manual apply and must be followed. The knee air bag is designed to inflate in higher severity frontal collisions, although it may inflate if the forces in another type of collision are similar to those of a higher severity frontal impact. It may not inflate in certain collisions.
Passenger’s side
