hi mate, i can only suggest that you get under your front end and have a look at your front diff. you want to check that your sensor plugs have a good connection. you have been in mudd and krudd latly so you may given this a bit of a knock.

All i got sorry

(on a side note, i did loose my 4wd to my front diff a little while ago, turned out to be a crushed vucumm hose. though it did not affect my tod display)
