Nissan Versa (N17): U0155 Lost communication (IPC)

Nissan Versa 2nd generation (N17) Service Manual / Transmission & driveline / Transaxle & transmission (TM) / U0155 Lost communication (IPC)

Description

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent malfunction detection ability.

Many electronic control units are equipped onto a 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 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.
