(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.
