ok, at the cadillac dealer i work at, we have an independent programming company we use that comes out to do any other makes of cars besides GM. They were there today helping a friend of mine. His 2001 caravan wouldnt pass emissions because it had a PCM fault code he couldnt get rid of. So he got a salvage yard PCM and they came out and programmed it and it fixed his problem. SO, i told them about my dilamma and asked them if they could do updates like this. They said yes no problem, they have the DRB3 and the correct stuff to do any make out there. So im bringing the car in tomorrow and they are coming to do it. He did say he would first see if it already has that bulletin software update in it. Now, how do they know if it is or is not already in it? The bulletin doesnt list a software number or anything..
