ABSTRACT:
The diagnostic method includes the steps of generating an acceleration signal related to the intensity of vibration in an engine; comparing the amplitude of the acceleration signal with a predetermined reference amplitude value; generating a fault indicator when the amplitude of the acceleration signal exceeds the predetermined reference amplitude value; determining a crossover drive angle value upon the amplitude of the acceleration signal exceeding the predetermined reference amplitude value; comparing the crossover drive angle value with a predetermined reference angle value; and generating a fault signal in the event the crossover drive angle value is less than the predetermined reference angle value.
