thanks...tennisshoes.. however that link does not cover the code I am getting.. it covers 12 to 14..my code is 15. It also covers 21 to 24, 32 to 35 etc.... but no 15.


Ok so it is an invalid or unlisted code, so now it gets complicated, you need to find a shop that has the old breakout box for the old system, I hate to say this but you may have to go to the dealer, the break out box will have to be installed and pinpoint test ran on each circuit until the problem is found, at the dealer this won't be cheap, so hopefully so independent shop in your area will have one. Sorry but that old maybe a bit of a problem as it didn't have a listed code.

Thank for your help. I have been dealing with it for 2 years now... guess it can wait.. just won't count on being saved by the air bag. .........the car is just turning 99,700... and many things are beginning to go wrong. I've only put on 30,000 in two years, and expect much less this year......................... Thanks again..............


Yes when the systems become outdated it get really hard to find anyone that keeps the old test equipment, it's like they are going to force into another vehicle by making even the equipment for working on it go away as if quit making any parts for it won't do the job. What happened to the days when things were simple, carbs, vacuum assisted brakes, and no high tech electronics, all gone, only the classics are left and people don't want to drive them cause they are afraid of damaging them especially with this fuel. But that's another story.
