Assignment of an identifier
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
The assignment of an identifier to a certain antenna of the vehicle is carried out automatically. Here, the antennas of the vehicle are activated successively with delays by radio signals. The time delays create a time window for each antenna in which an identifier found by this antenna can reply. The reply of the identifier in this time window enables allocation of the position of the identifier to a transmitter antenna.
