Hi , I'm new to posting and didn't know if the proper etiquitte is to tag onto an old post or to start a new one.
I dealt with the smog/system monitor ready issue this week. I wanted to share my experience just to keep things recent, so others who are researching could have confidence. We don't deal with smog regularly and it seems to change often which can make it tricky.
I returned my 2012 Ram 2500 6.7L back to stock, ( removed turbo back exhaust , uninstalled h&s tune). I knew I had to drive the truck a little so it could learn. Over the course of couple days I made a quick trip to my parents down the freeway, about 20 miles each direction ranging 65-75mph. And maybe another 15-20 miles of city stoplight to stoplight driving around town. I hadn't read about drive cycles at this point.
Three days after returning to stock, I went to the local Star Cert Smog Station. The Tech didn’t bother to smog the truck and told me to drive a few more days since it still had 2 monitors incomplete.
I scanned the truck and hca and htr monitors came up as incomplete. I believe it is the heated 02 and heated catalyst , both pertaining to the regen cycles from what I read on the drive cycle link someone posted.
I dreaded the thought of having to drive hundreds of miles (from what I read on these forums) for the regens and numerous DeN0x/S0x cycles to run , so I called around to several smog shops explaining to them what I read on here. They all denied me, I don't think they bothered to listen. Once they heard monitor not ready they cut me off.
Long story short, I gathered all the info I read on here and a few other posts and had to convince the original tech just to run the truck and hope for the best. It PASSED.
Its a shame that even experts aren’t able to keep up , and are turning away passable trucks. It makes me wonder what the guys are doing that aren’t taking it upon themselves to do their own research on sites like cumminsforum.
Anyway, Thanks to all the previous posters. You helped me out. What a pain in the butt, but i guess I'm really just out the quarter tank of gas I wasted trying the damn drive cycle. I gave up after realizing how many miles I was going to drive to initiate the regens.
Here are a few links from this thread and a few others I found. The site won't allow me to use html since i don't have any posts yet.
