"Service 4WD Drive"
If no codes are showing as active with the green tune scan,
Is there any merit in a 2nd opinion IE: The local Jeep agent to scan for any active codes only.
When I got that warning it use to stop my Jeep from setting cruise control but others don't appear to get that. 1-2 months later it went into limb mode, cleared codes all good for 200klm then Limb mode again.
My fix was New transfer case motor, new electronic box= transmission control module.
Long time since I have seen "Doc" on here, he had the "service 4WD" he tried lots of things, wasted a bit of money guessing and changing parts.
Last I heard he was going to run with the "service 4WD" until something broke.
Have you read thru his thread?
