Registration method of self-identification code of the tire pressure sensor unit, as well as tire pressure monitoring system and tire pressure sensor unit

摘要

The sensor unit body 10 of the tire pressure sensor unit 1, let comprises an external signal acquisition terminal 22 for rewriting the data of self-identification code of the ROM21, and the failure of the sensor unit, tires for exchange with winter tires and summer tires When you replace the wheel, by rewriting the same as the self-identification code of the sensor unit 1 before replacing the self-identification code of the sensor unit 1 after replacement, annoying task that they are associated with the vehicle mounting position with the self-identification code of the sensor unit I eliminate.
