I did a little searching and found another 06 where the same exact thing happened after unhooking the batteries. I his case a small ground wire was left slightly loose (just touching) for the ECM.
So make sure every connection is tight especially the smaller ground wire that goes to the edge of the qtr panel on the drivers side.
OK, I'm going to go out and undo that bolt and reverse the order to see if that makes a difference. I have the other wire (which you have mentioned for ECM) against the qtr panel, ground wire from battery, and head of bolt. I will retightened this. If that fails I will try ground wire from battery next to qtr panel and see if that makes a difference.
