You can get the code read for free at Autozone, Advanced Auto...ect. Light must be on at the time.

I would suggest AdvanceAuto over Autozone if you have one out there.. All the of the Autozones around here only pull the first code, not all of them.. I found out the hard way I had more than one :what:
