Nissan Murano: Dtc/circuit Diagnosis / U0101 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 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.
DTC DETECTION LOGIC
When ECM is not transmitting or receiving CAN communication signal of OBD (emission-related diagnosis) with TCM for 2 seconds or more.
