help
 

I programmed my truck bit messed up the settings so i re did it again and now it doesn't show if im in park drive ....... All other gauges and lightss work? Did my smarty do this or did a bulb just happen to go out? Thanks for the help

Flash it to stock and see what happens.

I have never heard of a smarty having that kind of effect on a vehicle..I would say a bulb, or fuse but that is just a guess..
