I just connected my code reader to the diagnostic port on the left fender well and followed the procedure for clearing all permanent memory codes. The AirBag Code 51 stopped initially, but then resumed. IE- after the reset, the code didn't begin flashing immediately as it had been.... it took a while before it resumed flashing. I presume this meant it was erased, but then re-established when I started the engine. Code 51 supposedly means there is a blown "Internal Thermal Fuse" in the control box behind the glove box.... which I did locate.
I'll also check the grounds on the sensors when I locate them. Haven't began searching yet.
Now to the question...
What is the procedure for changing this fuse?
What type is the fuse?
Readily available or a Ford/Lincoln Dealer only item?
