Just disconnect the battery for 10 mins or so.

No.
Must go to the dealer for a proper reset/reprogram.

Reset is different than a reprogram.

Correct, when the battery is disconnected it just clears the idiot light for a short time but codes are still stored.

I think we need to find out why the OP needs to reset/reprogram to direct him in the right direction.

This is to reset the PCM adaptive memory so it 'relearns' your vehicle and driving modes.

I know it has an impact because the two times I did it (after CAI install and after upgrading the exhaust and driving for a few days with them) the Jeep reacted very differently, especially when decellerating. It took 7-8 days driving every day for things to settle back down.

Cool. I'm sure someone will find this useful.

Yeah.......no thanks. I know a shade tree "mechanic" that did that once, he has the scar tissue on his arms and face from the burns to prove to ya sparks around a battery aren't too cool. His leaky battery exploded, hurt him badly, caught the vehicle on fire because he was actually shade tree welding and now doesn't have to worry about the check engine light anymore. Oh I know, he did it all wrong :roll:
