I was just coming to update this. Scanned the truck last night and the only code showing comes back "lost communication with BCM". I'm hoping it can just be reprogrammed. Also hoping I can find a shop willing to let me just bring them the BCM to reprogram so I can avoid the cost of a tow, especially if it turns out it's totally fried and I need to replace it.I just read this. I would use the scan tool and reset any codes. Then try again to start and then again check codes. .
