Methods and systems are provided for updating an in-use monitoring performance (IUMP) based on operation of an auxiliary device. In one example, a method may include using an engine model to estimate a duration in which a diagnostic routine is not completed due to operation of an auxiliary device driven by an engine and selectively updating the IUMP ratio based on a comparison of the duration to a minimum time duration needed for completion of the diagnostic routine.
