Abstract
A system (10) and method is provided for calibrating a tire pressure monitoring system using an EM transmitter (14). The present invention includes a first pressure sensor coupled to a wheel of an automotive vehicle (12). The EM pressure transmitter (14) is coupled to the pressure sensor (32). The transmitter (14) has a serial number associated therewith. An EM calibration device has a transmitting range. The EM transmitter device has an actuator. When the actuator is activated, a calibration signal (34) is transmitted within the transmitting range. The calibration signal causes the EM pressure transmitter (32) to transmit a serial number. A controller (16) is EM coupled to the pressure transmitter. The controller (16) receives the serial number and associates the serial number with a tire location of the vehicle.
