Mine did that once when I went out to start it up. Called the dealership and they had to have it put on a rollback and took to the dealership. Come to find out the pcm lost all of its programming and had to be reprogrammed. The dealership ordered me a new pcm to replace it with. Drove the truck until it came in.

Mine won’t even turn on. I disconnected negative terminal and now it won’t crank and anti theft code is on.

You will probably to have to get it into the dealer. Try pressing the start button with your key fob and see if it’ll start, I was told this is how you can start the truck if your fob battery dies.

That's what mine did, it kept asking for security code. I called the dealership and they told me to have it towed in. They reprogramed the pcm and everything was back to normal. Then he told me he would order me a new pcm because he didn't like the idea of the customer riding around on a pcm that might screw up again. I told him I would drive my truck until the new one came in. I don't like driving loaners.

If you cycle the run acc push start a couple times it will go away
