What auto parts stores do free diagnostic testing?

My check engine light came on while i was driving. I was wanting to take it somewhere to get it scanned to see what caused the light to go on and i was wondering which auto parts stores do it for free? Does brakes plus do it...What auto parts stores do free diagnostic testing?
None do "free diagnostic". Some do free "code reading" which is not even remotely the same thing. Code reading is just a matter of saying "your engine is running lean" or " you have a random misfire" or whatever the problem is. That by itself tells you almost nothing. Diagnostic is the art and science of finding out WHY you have the particular problem. Parts store guys don't do that. All they can do is suggest parts to replace that MIGHT help with the problem but usually won't.....

As the below said, autozone, checkers, and o'reilly will plug a scanner in and give you the codes but they're not mechanics and just use the service to get you to buy parts from them. It is not diagnostic testing and it only helps people who know how a car works.What auto parts stores do free diagnostic testing?
AutoZone %26amp; O'Reilly Auto Parts will do it for free.
