I just took my car in to have the code read on my 2000 Monte Carlo SS. It had no codes on the system and they went through the clear procedure. The only thing that I can find is the Fog lights are no longer working. Is it possible the fog lights are tied to the service vehicle soon light in the message center? If anyone knows please help me out as i have to have the Emissions test done soon and it won't pass with any lights on.

If the light is on there will be a code stored in history or past or present.
Find someone that knows how to read codes and post back code no.
