serch the archives on this NG for "service 4wd"

as typed, in quotes.

The possibilities for the light being on are limitless.

et.......

4wd controll switch encoder motor ft. diff actuatuator TSBs on controller programming

are the most common probs...and in my experience in the order I listed them.

A suggestion.....??...... most trannies shops will pull codes for no-charge!! Everyone I've ever known will. Fact-not Fiction.

Just don't approve any repairs before doing a repost here, and get some more advise.

good luck, and let us know.
