Method and system for calibrating a tire pressure sensing system for an automotive vehicle

The present invention relates generally to a system for monitoring tire pressures in an automotive vehicle, and more particularly, to a calibration method and system for calibrating the tire pressure system upon assembly and upon the maintenance of the tires. A system () and method is provided for calibrating a tire pressure monitoring system using an EM transmitter (). The present invention includes a first pressure sensor coupled to a wheel of an automotive vehicle (). The EM pressure transmitter () is coupled to the pressure sensor (). The transmitter () 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 () is transmitted within the transmitting range. The calibration signal causes the EM pressure transmitter () to transmit a serial number. A controller () is EM coupled to the pressure transmitter. The controller () receives the serial number and associates the serial number with a tire location of the vehicle.
