A system and method for decoding signals from a tire pressure monitoring system and a remote keyless entry system includes determining a signal strength of the signal. According to one aspect of the invention, the switching fabric includes a plurality of discrete switch modules, at least selected ones of which are hot-swappable with permission of the controller. Further, the output voltage supplied to the second connector is at a second value, greater than said first value, when the output of the first circuit is above a second threshold. The method further includes determining a plurality of hamming distances that are each associated with a respective packet of the plurality of packets other than the base header and are indicative of a number of differences between the respective header and another header of the plurality of headers.
