Ford Forum - Enthusiast Forums for Ford Owners - 04 Expedition seat minder deactivation won't work

I have read and followed the instructions on p.174 of the owner’s manual to deactivate the seatbelt chime. The computer flashes a confirmation code that DEactivation has occurred. BUT THE SEAT BELT CHIME DOESN’T ACTUALLY DEACTIVATE.

I repeat the procedure and the computer flashes a confirmation code that REactivation has occurred.

I then repeat the procedure again and the computer again flashes a confirmation code that DEactivation has occurred again. BUT THE SEAT BELT CHIME NEVER ACTUALLY DEACTIVATES.

Anybody seen this one before?
Any way to reboot the computer?
Ideas?
