Nissan Murano: System / Can Communication
System 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 independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
Refer to CAN Communication Signal , about CAN communication for detail.
System Description
Real time communications (signal exchange) among control units (e.g. ECM, CVT, ABS, and combination meter) via CAN communication optimizes engine torque and lock-up during gear shift and prevents engine speed from decreasing during deceleration...

DTC Description
DTC DETECTION LOGICTo judge malfunctions, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 signal fluctuates according to fuel feedback control.
The A/F signal computed by ECM from the A/F sensor 1 signal is constantly in a range other than approx...
