See attached photo of the diagnostic port I've got and the thread I've got going about the "OBD1 code reader." That is the only diagnostic port I can find on my car. It is a non-California version, so it doesn't have the blink code reader diagnostic port I hoped it would. Is there some way I can read fault codes for the SRS system on this port? Does it also serve as a blink code reader on some of the terminals or is everything duty cycle?

My SRS light comes on about thirty seconds after I start the car and stays on for the duration of the trip. I want to find out which part(s) is bad before I start replacing things willy nilly.

Thanks for any advice.
