Nissan Murano: Dtc/circuit Diagnosis / U1000 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 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.

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.
