Advance Trac light on and blinking 4x4 lights help

[mac2k]

I have a 03 ford expedition with 5.4

It just started the other day. I did some research and found the thread about the violet wire.
I some looking and found the violet wire it's still intact. I have no rust or water in the area of the wire. Tried to pull codes with no luck. The 4x4 lights blink once and then 2 more. I don't want to go to the dealership unless I have to.

Thanks

Mine was doing this but I think it was due to something different... I eventually had the rear wheel bearings replaced and abs sensors and the steering rack had to to be replaced due to a hole in it

*UPDATE* The 4x4 lights are no longer blinking. But the advancetrac light still remains on. I know the 4x4 lights still work as they light up at start up "system check". No codes yet. Still would like to get some help before I have to spend a fortune at the dealership.
