Did you pull off the neg battery cable for a while? </div></BLOCKQUOTE>

On my recently-traded in GMC Sierra, with the same basic type of computer. Twice in 3 years (about 1 year apart), I had the SVC 4WD light come on, and the truck would not go into Auto-4WD, 4-HI, or 4-Low. Disconecting the battery cable for a few seconds fixed it both times.
