    Mmm ok, I think you are going to have to just start pulling fuses in the hope it kills whatever it is interrupting the bus. Previous poster gave a hint as to where the BCM fuse is.

    I am sure when people have issues like this on the LLY it's always the Radio and BCM fuse that solves it. As for what not to pull, I don't know.

    There can be up to four fuses for the body control module. One is in the underhood panel and there will be one, two or sometimes three more in the interior fuse panel. Pull anything labled "TBC". "TBC" is Truck Body Computer. Hope that helps.

    Pulled all of the tbc fuses and a ton more fuse box is pretty empty made it the farthest it has but still only 41k out of 928k so really really far away.

    Where are you located? Maybe you can find somebody with a bench narness to flash teh ECm that way so you can rule out the data bus.

    i have found out that you can pull every single fuse out of the in truck fuse box and still communicate with the truck. its still is trying to load but stops at random spots and says retrying previous block
