As the name implies,when an initialization is done, the previous key IDs will be cleared. After completing the initialization operations, you need to learn or register a new key ID, otherwise the vehicle will not start.

Before initialization,you need get a 4-digits PIN code which generated by a five digits BCM identification number.You need this calculator (Nissan SuperCode Calculator)

Access the system via AENO2C version and enter the initial “START” menu.
