Review on MUCAR CDL20 OBD2 Scanner - Check Engine Code Reader And Diagnostic Scan Tool For All OBD II Protocol Cars Since 1996, With O2 Sensor, EVAP System, And Smog Test Functions by Jonathan Cartwright

This is such an easy to use OBD2 Scanner. It doesn't require any batteries and it will work on over 100, 000 different car types. My check engine light was on in my mazda and in my dodge caravan and this worked very easily and gave the codes to diagnose the potential problems. It works just like the kind at the auto place. You has many different options like clear code ECT. It is very accurate and helped me get my car to pass inspection. Great price and value. Definitely convenient to have on hand
