various emissions-related systems on the vehicle are operating properly and are

vehicle's Monitors have run and completed their diagnosis and testing (as
described in Chapter 2.5), and which ones have not yet run and completed
testing and diagnosis of their designated sections of the vehicle's emissions
system.
