VEHICLE MOTOR POWERED MECHANISM DIAGNOSTIC SYSTEM AND METHOD USING A HALL EFFECT SENSOR

A diagnostic system for diagnosing a motor powered mechanism on board a vehicle includes a current detector for detecting current drawn by a motor of the motor powered mechanism, a hall effect sensor operatively coupled to an output of the motor for generating a hall effect position signal, and a controller configured to receive the detected motor current and the hall effect position signal and to determine an obstruction or fault condition associated with the motor powered mechanism based on the detected motor current and hall effect sensor signal.
