My 2008 Hyundai Santa Fe had an airbag light on the dashboard. The code readers at the local auto parts store can only diagnose engine faults, so I had a choice of going to the dealer and getting "dealer treatment" or buying my own code reader. I bought it because of the Autel brand and because it's a lot cheaper than those sold for professional use. It is easy to use and requires no batteries. I was able to quickly determine that the car's "clockspring" was the culprit by using this code reader and applying audio troubleshooting.
