[QUOTE="smurfslayer, post: 1605140, member: 21926"] I presume you’re setting DTC’s here, you can pull the codes with a reader or get / use FORSCAN which allows you to make a printout. listing all the codes will assist for sure. How is your battery health? a couple of quick checks you can do to see if the truck thinks there’s a battery issue - for 802a trucks, try the passenger side unlock by putting your hand behind the door handle. if it unlocks as normal, the battery should be ok, assuming nobody messed with the battery management system in forscan - once your truck is warmed up, ensure auto stop start is not disabled and see if the truck shuts off at a stop sign or stop light. The driver’s menu has an option to display this function. if it doesn’t engage it will give you a reason why Have you traced the wiring to make sure previous owner did not tap into something connected to one of the major modules in the truck? The lights are pretty easy to validate, what about the radar detector and radio? I think you’re saying that I think you need to be sure there’s actually nothing tapped into or tied to anything that could interface with any of the truck modules first, just in case. In other words, make sure you know, not that you think you know. If you can confirm this, then the stealership should engage to assist. If you find something tapped into or tied to a harness wire, or accessory that attaches to a harness, that could be a thing. Those wires are notoriously thin, easy to damage so easy to cause trouble. I’d remove any accessories like this one at a time and retest until you were ‘clear’. [/QUOTE]
