Follow-up: I took the truck in to the dealership yesterday and they had two recalls to conduct. In addition to the airbag recall, there was a shifter lever recall. The shifter lever recall was the only one that needed access to the ecm. Well, after they did the airbag one, they came out and told me they could not access the ecm with their computer, so could not do that one. They said I had to take it to a different dealer. ANYWAY, I am perfectly fine with it in the long run. My shifter works great and they didn't get into my ecm to (potentially) mess up anything. And he did tell me it might activate the horn blowing in reverse BS.
I did find out this morning that I do have one problem: my heater blend door control is messed up now, probably from them disconnecting the batteries. When in the COLD position it is cold, when it's in the HOT position it is cold, but halfway it puts out heat. I assume it just needs calibrated.
