Truck Is Freaking Out!

[NomadPNW]

So started the truck today and service lights came up and the went away. Like service ABS and a bunch of other went by super fast. They are all gone now. However the HVAC is stuck on high heat but says LO, you can’t adjust the temp and sync if not an option. Passenger seat controls are missing in the information along with all the cameras all gone.... I reset the truck and had the truck with out power to see if it would help.... nope. It goes into dealer Tuesday but does anyone have any ideas?

Check all the underhood grounds.

Check (push in) all fuses and relays in the PDC.

Pulling power long enough to reset the radio, some things can take a while to come back.

Pull the battery cables off wait 10 mins then touch the positive and negative together before reconnecting them

Check the batteries. I had very similar issues to yours, had one bad battery. Replaced both batteries and all issues stopped.
