Abstract: A wireless programming method for tire pressure detectors includes the following steps. A wireless programmer sends an activating command. The tire pressure detectors send a responding message. The wireless programmer receives the responding messages and records identification codes in the received responding messages. The wireless programmer sends a stop-responding command to make the tire pressure detector with the identification codes, which is recorded in the wireless programmer, enter a stop-responding mode. The wireless programmer sends the activating command again. The tire pressure detectors not in the stop-responding mode send the responding messages. The wireless programmer receives the responding message and records the identification code in the received responding message. The wireless programmer sends a code to the tire pressure detectors corresponding to the recorded identification code to program the code.
