Abstract
A low tire pressure warning system has a pressure sender and a radio transmitter in each tire, and a vehicle mounted receiver includes a microprocessor controller programmed to automatically learn the IDs of the tire senders. An ID message and pressure report is transmitted from each sender and recorded in memory as main senders presumed to be those on the vehicle wheels. Subsequent new IDs are accepted as reserve senders. By monitoring sender activity the main senders are determined to be healthy or damaged and are replaced when not functioning by new sender IDs which are functioning.
