airbag light

I have a 1992 town car with the 4.6 liter engine. The airbag light is blinking. I counted the pattern and it is 10 blinks then a long pause then 10 more and so on. I figure this is a trouble code 10. I have asked the dealership about the code but there books do not go back that far.
Can anyone tell me what this trouble code represents. I have checked the fuses for the airbag and they are fine. the car has never been in any kind of an accident. any ideas would be great..

Thanks
