1. An electronic device in a vehicle tire condition monitor system, the electronic device comprising:
- an antenna receiving respective RF signals from a plurality of sensors associated with respective tires of the vehicle, each of the respective RF signals representing a condition of the respective tire and including identifying information of the respective tire; and
a processor receiving the RF signals from the antenna, converting the RF signals to a proprietary serial bus formatted message, and transmitting the proprietary serial bus formatted message to an electronic, control unit via a vehicle communication bus, the processor acting as a single conduit for the condition signals from any of the plurality of sensors associated with respective tires on the vehicle, and if the electronic control unit does not receive a proprietary message from the processor within a predetermined response period, the electronic control unit alerts an operator of the vehicle of a status of the respective sensor.

Abstract
An electronic device includes an antenna that receives RF signals from a sensor associated with a respective tire of the vehicle. The RF signals represent a condition of the respective tire. A processor receives the RF signals from the antenna. The processor converts the RF signals to a proprietary serial bus formatted message. The processor transmits the proprietary serial bus formatted message to an electronic control unit via a vehicle communication bus.
