Electronic Locking Diff not Locking

Hey there, I have 2017 F-350 6.2L. It has the Electronic Locking Diff (ELD) but it seems not to engage. When I puill the **** out to engage the ELD the light comes on for about 30 seconds and then shuts off. If I go to the off-road screen on the dash the ELD lock turns orange but then it just has the moving hash marks and won't turn solid to show that it has engaged. This does not work in 4X4 or 2WD

I looked at the fuses that I thought would be associated with it and all of them seem fine. Has anyone here experienced this as well? Any other good Ideas to check? Any help would be appreciated.
Thanks in advance for any help.

Check the wires and connector on the rear differential, can't miss it.

Are you moving when the light goes out...??? Once you go faster than 25 to 30 MPH the E lock dis-engages, and re-engages below 20 MPH or so...

So I guess this is what it is! I assumed that the locker would stay engaged but it unlocks at 50kph (30mph). I needed to learn what the graphics meant as well. The hash marks indicate that the drivetrain is currently moving, the graphic then hgoes solid when stopped. Long story short, I guess there isn't anything wrond with the locker. Thanks for the help in pointing me the right way.
