What was particularly strange on this install, was he succesfully flashed the truck. When his log turned up jiberish, and then parked it, that is when all the fun began.
We went over the importance of all the above mentioned items, spent many hours bringing all software and firmware to date.

Battery voltage probably is underappreciated. I have eased (full) flashing problems just by having a battery charger hooked up.

I had suggested that Nemo reattempt the flash while still at the dealer, but he was understandably gunshy after 3 days without a vehicle.

Paul did mention that the BCM fuse may play a big part.
