Abstract
An enhanced wheel data processing unit may analyze tire air temperature data from a tire pressure monitoring system (TPMS) and antilock brake system (ABS) wheel speed sensor fault codes from an ABS controller within a vehicle. When the enhanced wheel data processing unit determines that the tire air temperature is above a predetermined threshold for a given tire and that an ABS wheel speed sensor fault code exists for the wheel end corresponding to the same tire, the enhanced wheel data processing unit may initiate a vehicle shutdown or derate procedure. The vehicle shutdown or derate procedure may include instructions to give an operator of the vehicle a warning indicator for a predetermined time period before shutting down or derating the engine power to the vehicle.
