Your hex code should be there. If that doesnt work you can unplug it with the key off, then plug it back in. I used to have to do that all the time when the heat would cause the display to shut off. The hex shows up in like the first or second screen after you plug it back in and turn the key on

Bingo, those are both good ways of getting it.
