How To Diagnose Your Check Engine Light For Free

There are a few different companies that offer free “Diagnostics” or “Scans” of your vehicle to let you know why your engine light is on. In fact recently more businesses have been jumping on the bandwagon in order to bring customers into their stores.  I won’t mention any names for obvious reasons, but I am sure you have seen, heard or even worse been a victim of these companies, who are heavily advertising on both TV and radio.

But when something goes wrong, like your check engine light comes on or you hear an unusual sound from underneath the hood,  you may find your car not familiar as it should be. That’s where a car diagnostic test can come in handy.
