Hello and welcome to the forum, glad to have you join us! Sounds like a nice truck, any pics you can share? We'd love to see your ride in the gallery! I agree with Brad, good place to start is resetting the computer since it seems the problems started after the battery drained completely. Good luck and be sure to keep us posted! Lots of great people and info here so any help you need, just ask and I hope you enjoy the site!
