ABSTRACT:
A system and method that, upon connection of a trailer to a tow vehicle, a trailer brake controller informs a tire pressure monitoring system to begin monitoring information at the TPMS and at the same time, activates the initiators, i.e., the electromagnets. Sensors respond to the electromagnetic field that is generated by electric brake magnets. As a result, the sensors transmit RF signals that are received by the tire pressure monitoring system. Transmissions from the sensors are decoded in a controller and processed as necessary for tire pressure monitoring automatically calibrated to the tire pressure monitoring system and the system can request the pressure data from the sensors by way of the low frequency field generated by the electric brakes.
