i have had the similar prob, after i R&R'd my clutch the 4wd indicator light wont turn OFF. i have got under thier and connected and unconnected and brushed and electro greased to no avail. i was curius cause all i did was take it apart and put it back together, that is the only light that is on and i haven't been able to try a scanner yet.
