Otherwise you can just reset the check engine light in the parking lot of the smog station and pass before the computer gets through all the test cycles.
(I got REAL familiar with running the test cycle when I was fighting with the evaporative emission system in my Astro Van.

Nope, newest stuff, diesels have weird easy requirements. Just a particulate test and verify no check engine light. I've never seen the techs turn a diesel off to check the light.
My last house had a woodstove that complied with EPA, had a swirl system and a cat, but out it came when the house got sold.
I am under the impression that it took a couple of cycles to cause the computer to go into test mode, AFAIK, RESET in the parking lot causes a fail here for gassers.
