Just tried my truck sitting in the garage, both off & after I started it....nothing under PCM.Same here. I know my truck was built, but still at plant.
I also checked a VIN I was tracking from a nearby dealer. It has been delivered to its customer and removed from their website. It also has hundreds under BCE. Nothing under PCM. Not sure if this can tell us anything. Guess it still can indicate whether your truck has been built, but cannot tell the reason why the truck is stuck at the plant.
