OBD2 Scanner Bluetooth Car Code Reader Diagnostic Tool Wireless OBD Car Code Reader Check Engine for Cars and Trucks for iOS and Android

This is my second one. This is a great diagnostic tool. Not only can you live view your engine stats, but you can look up error codes and clear them. Pro version of the app of course offers more, but the basic will give you exactly what you need to start being "one with your car" Stop wasting money going to have a "Check Engine" light diagnosed. Get this and do it your self. You wont regret it. Works on all cars that have a OBD port and use OBD-II **most cars from 1996 to current, though it WILL NOT DIAGNOSE or work with cars who use OBD-I.** (My car is a 94 chevy caprice and will not work.) You can keep it plugged into the port even when you aren't accessing the app/data, and if you dont want it there...toss it in the glove box.

So while this was plugged in while I was driving, my dashboard shut off and multiple codes appeared. After pulling over, I turned off the engine and it would not restart. I wasn't sure what was going on but was able to get the reader to show multiple electronic codes on my phone. I cleared the codes and tried to restart.No joy. Same codes reappeared. I cleared them again and pulled the reader.Engine started and dashboard was fine. Plugged the reader back in and tried to reconnect my phone to it. Nope. Haven't been able to connect to it ever since.Bought a better unit. No issues with that one.

Decent

Works great

I guess it wasn't compatible with my car.
