Hey Scotty I was wondering if u got any idea of how to fix the issue I'm having. I bought a 2002 Toyota Corolla . The car runs great no check engine lights since i got it .but had a battery which was getting old so I swapped it with a new one which reset the system . I took it to get smogged and they tell me to drive it a hundred miles and come back so I did. but the catalytic system won't ready itself to be smogged. Since then I have driven it well over 600 miles on and off the freeway. the car still runs just as good as when i got it and the engine light still is off.  but the car still won't ready its system so I can get it smogged and registered..Any ideas 💡 of what I can do to get this things catalytic system to become ready so it can finally be smogged???
