The TPMS transmitter is mounted on the valve stem of the tire. The RF receiver is integrated on the ECU. The ECU contains the driver circuitry for the LF antennas (4 per system) and the integrated RF receiver (which has been already homologated). The LF antennas are only necessary to locate the tire position after a tire change. The antennas are fixed on the steering stub. When the antennas send a 125 kHz signal to the TPMS transmitter the transponder will be activated and the location of the tire and the corresponding TPMS transmitter can be read. The localisation function enables the vehicle driver to get information about which tire a pressure loss has been detected.
