FIXD OBD2 Scanner

Mind that this only works with the FIXD dongle. Will not work with 3rd party dongles. The good thing about it is that it gives you data in plain English, i.e. it doesn't show you just numbers that only mechanics understand. The downside is that it requires you to create an account and it uploads all your scan data automatically. If you have no Internet connection (e.g. underground parking lot) it will scan but will not show you the results until you have Internet access.

Worth the money. More importantly you become an informed customer. You can troubleshoot the situation before the mechanic sees the car. So, you are not taken by an unscrupulous garage. For me I use it many times...When I was checking out used cars. I was also able to figure out that a gas attendant didn't put the gas cap on correctly. It saved me a trip to the garage. It is a tool, and the more you use the tool the better you will get figuring out a problem.

This is a great basic tool to easily diagnose a problem or head off a larger potential problem. I think everyone should have one. You should also use it when shopping for a used car. It will tell you how many miles since the check engine light was last cleared. That's very valuable if the seller is trying to hide something because sometimes it takes some time before a code will register again and cause the check engine light to come back on
