Welcome to the club of warning lights. See my thread if you wanna see the hassle I'm dealing with. Start with the easy stuff you feel you are capable of handling; replacing battery terminals, cleaning negative grounds, etc that have been suggested in plenty of threads regarding these intermittent warning lights. Hopefully some of those little fixes will cure your "Serv 4WD" light. They didn't do much for me so a trip to a good shop is in the future.
