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.

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; anda 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. 2. The electronic device, as set forth in claim 1, wherein: the processor converts the RF signals to the proprietary serial bus formatted message that is transmitted to an antilock brake system electronic control unit via the vehicle communication bus. 3. The electronic device, as set forth in claim 1, wherein: the processor receives a control message from the electronic control unit via the vehicle communication bus. 4. The electronic device, as set forth in claim 3, wherein: the control message requests a status message from the sensor via the processor. 5. The electronic device, as set forth in claim 1, wherein: the RF signals include an identifier tag identifying the sensor; andthe processor includes the identifier tag in the respective serial bus formatted message. 6. The electronic device, as set forth in claim 1, wherein: the formatted message transmitted to the electronic control unit identifies an inflation pressure of the respective tire. 7. The electronic device, as set forth in claim 1, wherein: the formatted message transmitted to the electronic control unit identifies a temperature of the respective tire. 8. The electronic device, as set forth in claim 1, wherein: the antenna receives the respective RF signals wirelessly from each of the plurality of sensors associated with the respective tires of the vehicle. 9. The electronic device, as set forth in claim 1, wherein: the electronic control unit monitors the condition of the respective tire and also performs an additional function on the vehicle. 10. A system for monitoring a condition in vehicle tires, the system comprising: a vehicle communication bus;an electronic control unit communicating with the vehicle communication bus;a plurality of tires on the vehicle;a plurality of sensors associated with the respective tires, the sensors transmitting respective RF signals based on respective conditions of the respective tires and including identifying information of the respective tires; andan electronic component communicating, with the vehicle communication bus, the electronic component including: an antenna receiving the respective RF signals from the plurality of sensors associated with a respective tires of the vehicle, each of the respective RF signals representing respective conditions of the tires; anda processor receiving; the RF signals from the antenna and transmitting a proprietary message, based on the signals, to the electronic control unit via the vehicle communication bus, the processor acting as a single conduit for the signals from any of a 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. 11. The system as set forth in claim 10, wherein: the vehicle communication bus is a J1939 communication bus;the messages are formatted for the J1939 communication bus. 12. The system as set forth in claim 10, wherein: the electronic control unit determines if the pressures in the respective tires is within a predetermined range. 13. The system as set forth in claim 12, wherein: the electronic control unit is an anti lock braking system electronic control unit. 14. The system as set forth in claim 10, wherein: the electronic control unit converts the RF signals to a J1939 protocol formatted public message. 15. The system as set forth in claim 10, further including: a second antenna receiving second RF signals from a second sensor associated with a respective second tire of the vehicle, the second RF signals representing a condition of the second respective tire; anda second processor receiving the second RF signals from the second antenna and transmitting a second proprietary message to the electronic control unit via the vehicle communication bus. 16. A method of monitoring conditions of tires on a vehicle, the method comprising: transmitting respective RF signals from a plurality of sensors associated with respective tires of the vehicle, each of the respective the RF signals being based on the condition and including identifying information of the associated tire;receiving, the plurality of respective RF signals from the sensors at an antenna;converting the RF signals, in a processor communicating with the antenna, to a proprietary serial bus formatted message;transmitting the proprietary serial bus formatted message from the processor to an electronic control unit via a vehicle communication bus, the processor acting as a single conduit for the signals from any of the plurality of sensors associated with respective tires on the vehicle; andif the electronic control unit does not receive the proprietary serial bus formatted message from the processor within a predetermined response period, alerting an operator of the vehicle of a status of the respective sensor. 17. The method of monitoring conditions of tires on a vehicle as set forth in claim 16, wherein the step of transmitting the RF signal includes: basing the RF signal on the condition of the associated tire and a temperature of the associated tire. 18. The method of monitoring conditions of tires on a vehicle as set forth in claim 16, wherein the step of transmitting the proprietary serial bus formatted message includes: transmitting the proprietary serial bus formatted message to an antilock brake system electronic control unit via the vehicle communication bus. 19. The method of monitoring conditions of tires on a vehicle as set forth in claim 16, further including: receiving a control message in the processor from the electronic control unit. 20. The method of monitoring conditions of in tires on a vehicle as set forth in claim 19, further including: in response to the control message, requesting a status of the sensor.
