The AFM's are easy enough to bench test with a multimeter and the page from the manual.
Brian Holm once said that the failure rate is quite low. If anybody would know, he would. Although, once I had one fail, but anything is possible on a 20 year old car.
Let me know if you are still having trouble and I will dig up the page and write up a logarithm to bench test it with a multimeter.
