1. A method for automatically updating a remote tire monitor system of a vehicle, the method comprising:

  • storing identification information for each tire monitor of a plurality of tire monitors of the vehicle;

    receiving an identifier transmitted by a transmitting tire monitor;

    receiving a transmission indication from a receiving radio frequency (RF) detector associated with the transmitting tire monitor, including detecting RF signals at the receiving RF detector;

    without demodulating the RF signals, detecting a modulated electrical signal on a wire coupled to the receiving RF detector to produce a wireline indication in response to the RF signals; and

    at a control unit, detecting the wireline indication as the transmission indication; and

    when the identifier does not produce a match with the identification information, updating the identification information using the identifier;

    and receiving RF signals at an RF circuit;

    demodulating the RF signals to receive tire information; and

    locating the identifier in the tire information.
