RE: Service Engine Soon Light Came On?
Service engine soon is the same as a "Check engine" light. Your engine is throwing some kind of trouble code. Yes, an Auto Zone or Advance Auto parts will usually scan for codes for free. Pep Boy's won't, they want you to schedule an appointment and spend $100 for their diagnostic service.FYI, the scanner you will use at Auto Zonemay not be as specific as what the chevy dealer would use,depending on the problem. If you get a code for catalytic deterioration, you need a new cat (simple). If you get an evaporative emissions code, it might be your gas cap, or a whole list of other things in the system (not so simple). Good luck.
