OK so here's an update........ Only Ford can clear/check the codes related to that stupid wrench icon. Mine was lit because my coolant was low (at min mark). I'm sorry, but that's about the most ridiculous and asinine thing for Ford to have such a high tech car with Sync etc and not be able to tell the owner, "Hey you're coolant level is low." Nothing but a scam to get money. Oh well, 135 later and icon is now gone. Coolant system topped off and pressure tested, no leaks. FML!
