Abstract
A method of rationalizing operation of a vehicle wheel speed sensor is provided. The method includes the steps of receiving an output signal from a longitudinal accelerometer, receiving an output signal from a wheel speed sensor, determining whether an acceleration event exists based on the output signal from the longitudinal accelerometer, evaluating the wheel speed sensor output signal during the acceleration event, and determining whether the wheel speed sensor signal exceeds a set threshold value during the acceleration event.
