Yes, but once I'm in the truck with the key on, everything works as it should so testing doesn't yield any new info. It's almost as if the truck is acting like an interior light was left on too long and it kills power to the modules in order to save battery life, but nothing is drawing from the battery while at rest. I'm pretty sure these trucks have that feature, just not sure which module controls it. Would it be the body control module?I’m somewhat surprised no other body control errors if it’s not communicating. I’d guess the original module is the factory one. Can you test it with your new scanner?
