I have a 1997 900S Saab (2.3 L - 4 Cylinder, non turbo). I have to get the exhaust checked for inspection on my car (Califonia SMOG) and when I took it in they told me that it failed because the engine self diagnostics did not complete. I had the battery disconnected about a week ago, but have driven for about 10 hours since that. Does anyone know when the self check will complete and how I can check when it does? Thanks!
