4X4 Temporary unavailable

This happened to a friend of mine quite frequently. He found out there is a service bulletin for it. Talk to your dealer and ensure you have all the latest software.

On the trail, you might be able to clear the error by disconnecting the battery and wait a few minutes.

Otherwise, you need a device that will let you clear the errors, like a diagnostic tool, forscan, or the Ford Procal tool.

Also, sometimes when in 4L or 4H and using goat mode dials and attempting to switch into or out of 4H/4L, you have to switch out of the goat mode first.
