In this day and age you don't have a scan tool? Buy one of these:

It's less than $10 and it talks to an app on your phone. You can erase codes with it. I use a program called "Torque" available in the PlayStore for a couple of bucks. You will love it if you are any kind of gearhead. Am I not right guy's??
