Try to plug in the tool that will give me the codes and the thing I'm plugging into has no power. Any suggestions?

So I'm trying to plug a diagnostic tool to get the codes of whatever sensors or whatever that might be a problem but there's no power to the dealer under the steering wheel. Fuses, seem to be good but this beast has a myriad of electrical issues such as no action from buttons like trunk latch, suspension options (with those lights displaying on dash, stock radio has power but no sound, back center brake light didn't work, I replaced, still no action so I wired it into the left brake light so all three work together. But not being able to get the codes is a drag. Is their some way to get the codes from the dashboard like where it says "tire pressure is low"or " you have 13 miles left""??

Did you check the fuse? There's a 10A fuse in the passenger footwell fuse box for it

After you plug in your diagnostic tool into the OBD2 port did you try KOEO (Key On; Engine Off)?
