A fresh flash through HP tuners would do it. Pulling the pcm power will reset most learned data. A code reader will clear your stored/written fault codes. Really just depends on what exactly they mean.

And I'm stating that for the last 15 years not all "learned" data is reset, and I specifically named written fault codes. If you are saying what he needs to do requires only simply removing PCM power for 5 minutes then why doesn't the service manual simply state that? And, if what you said is true, its already been mentioned. So congrats, you've contributed nothing

I certainly don't know which "learned" parameters get reset by cutting the power; it would be useful to see a list of which get reset and which don't.
If you have tuning software like HP-Tuners or EFI-Live, you can download the current tune to a file and immediately upload it again; I also believe this resets everything. Of course this will cost you tune credits, but you probably have already used them for this car.
