2004 hemi pcm replacement

Thank you! Just saved me a bunch of time and some cash !
I guess its off to the inspection station to get my inspection stickers. The indicators seem to be working properly for the ac and mirror heat... maybe it was just an initialization thing since the battery had been disconnected.
I'll drive it a bit and see if anything else pops up.

You may need to drive a couple days so the CARB monitors can complete.

OK, sorry. I was under the impression you got the PCM from a reman place, which usually will input the VIN prior to shipment. My bad. Some emission testing centers, like the ones in my area, don't see the VIN other than when they look at the VIN plate.

No problem, passed emissions today!
learning experience...
1. the pcm is on the firewall, not under the fuse box
2. testing the wiring is worthwhile, before buying the second o2 sensor
3. used pcms are a viable option, they have a sticker that identifies the flash version
4. mileage isn't in the pcm, but the VIN is
5. In PA, the VIN is collected as data with emissions testing - you won't pass unless it matches your registration.
Now onto the next issue, persistent ABS problem (no matter which pcm is installed), I think a new thread will appear soon...

Curious... when the dealer flashes the pcm, can they make some minimal adjustments to the data/code that is present, or is it fill out a form and flash all entries?
What was strange, is when I got home from the dealer, I checked to see if all tests were complete for inspection - and they were. Seems like it should have taken more than just one 10 minute drive... made me think that the flash didn't clear the CARB monitor data. My scan tool showed the dealer did update my VIN.
