mine has been flashing 51 since i got my contour.the dealer i bought the car from sent it to a ford dealer to fix.ford held it for 2 days and didnt do nothing.i was told that fuse is not replaceable and the whole diagnostic module 250 to 300 dollars needs to be replaced.ford would not replace the damn thing until they found the swinging short. i said give me my damn car back .ill wear my seatbelt! i also saw posts here on how to eliminate the whole airbag system light ,bags etc.
