The air pressure of a tire of a vehicle is sensed. The operational mode of the tire is determined. Based upon the operational mode of the tire, the size of a message preamble is selected. A message to be transmitted to an electronic control unit (ECU) in the vehicle is formed. The message includes the preamble and a payload portion, and the payload portion includes the sensed air pressure. The message is transmitted to the ECU. |
