ABSTRACT:
The time needed to verify proper operation of a fault detection system or to verify the impact of the replacement of a component in the system being monitored is reduced without substantial increase in the possibility of false indication of failure or false indication of proper operation by employing a geometric moving average with a variable time constant reset to a minimum value upon initialization and gradually increasing to a maximum value. Motor vehicle systems and components are monitored and a diagnostic indicator annunciates faults to alert the vehicle operator to malfunctions.
