1. A code learning method for a tire monitoring device, said method comprising the steps of:

  • providing a plurality of sensor modules being installed to a plurality of tires in a motor vehicle, each sensor module having a wireless signal transmitter for transmitting a signal, said signal including a specific code for a tire condition and a specific code for the sensor module;

    providing a plurality of antenna modules, each being installed to individual sensor module, for receiving the signal;

    selectively coupling the plurality of antenna modules;

    dividing the signal into a data signal and an amplitude signal;

    confirming an intensity of the amplitude signal to locate the installed position and the specific code of the sensor module from which the signal is being transmitted.
