No OBD port voltage

I don't have any voltage at the OBD port. Checked all fuses and connections, everything seems fine. Can't check codes or change programs. Any help?

what fuses did you check. If I remember correctly, doesn't the OBD2 port tie into one of the power outlet fuses. I would re-check those and change the bad fuse and try again. I think that is the right fuse, it has been a while since I changed it out. Hope that works.

the OBD2 port is tied with the cigarette lighter fuse.

And that applies to ALL OBD-II compliant vehicles as well, if we are talking about pin #16 of the DLC. This pin is the "hot at all times" pin on every OBD-II vehicle.

That’s the same answer I got from the dealership so I would assume that everyone is correct, but the only problem I have is that both the cig lighter and the aux have power and every fuse in the truck is good. Appreciate the help. Any other ideas or experiences?
