I'm a Master Mechanic of 30 years, my home scan tool got melted in a house fire. Picking up medicine from Walgreens and I saw this. Ok, 20 bucks, so I thought I'd check it out. I figured it would do basic stuff until I replaced my good one. This is a joke, said no problems found and my check engine light was on. The device would do NOTHING else. Going to take it back. I can get more information with a couple of pieces of wire by shorting two contacts on the plug. That will at least blink the code number then you can look the code up. Not worth the effort to plug it up.
Bottom Line: No, I would not recommend this to a friend
