OBD2 Scanner & WiFi Car Code Reader – Clears Check Engine Light – Diagnose 3000 Car Codes - Wireless Car Diagnostic Scanner – Auto Scanner for 1996 to 2016 Vehicles (iOS & Android Devices Only)

Saved me some money already with it. Not having to rely on mechanics at a shop for such a simple diagnosis for check engine lights. Yes, I know there other issues involved. But this initial information on getting codes, then researching starts with one of these.Have scanned a few vehicles so far. Seems to be accurate with relevant information. It doesn't fix your problem or tell you exactly what's wrong. That's on you or a mechanic to do. Being able to get codes and clear them once you have fixed an issue is very niceOnly issue I remember with this is it's a WiFi device. I didn't see anywhere in manual or online that you MUST turn off phone Bluetooth AND mobile data for this to work. When I contacted support, the conversation went all in the wrong direction because it had a simple solution for not connecting. That's not the first thing they suggested and I find that aggravating. ONLY have WiFi turn on phone for appThe other nice thing is having some readouts available while you are driving if you were looking for something else as cause for an issue.I would buy again for sure

This is a very handy tool to have if you're a DIY kind of person. Just plug it in, connect with an app, and you have access to several dynamic parameters and can view/clear DTCs. I have used this on a 2006 Toyota Tacoma, 2005 Toyota Highlander, 2012 Toyota Corolla, and a 2006 VW Jetta. It worked perfectly on all 4 cars. I even used it to read a DTC that was causing the CEL to illuminate and was able to promptly fix the problem and the code cleared on its own. The free app that is designed to be used with this tool will get the job done. It has a premium feature for 4 bucks that allows you to save and record data and what not. In the future I may purchase a different app that is a little more intuitive and nice looking. The tool itself can be used on a car that isn't running, however I don't recommend it as it seems to use a lot of power and may drain your battery. Also, don't leave it in when you are not using the car as it has a constant red LED and WIFI signal that will surely drain your battery! It's not a set and forget kind of thing. It is worth noting that this is in fact a WIFI device and not Bluetooth. After looking at many other Scanners, many of them were bluetooth and when I bought this one I thought it was bluetooth too because I wasn't paying attention. Not that big a deal, but I would've preferred a bluetooth version because the WIFI signal interrupts other WIFI and cellular connections so you can't use the internet at the same time. Bluetooth would allow this. Just a thought in case you also didn't notice that this was a WIFI device. BTW I use an iPhone 6 in case you were wondering about compatibility.

First of all, in whatever of my 3 cars I use this in, it mounts backwards - so the lights are facing away from me. That means I can't see when it's connected unless I use a mirror.Second, you usually need to buy add ons for the app to really use it successfully with your particular vehicle. Third, it often disconnects itself. All that being said, it did what I needed it to do.I was using it to clear the MIL (check engine light) and then monitor the results of the computer tests as you drive a specific # of miles. Then you know when you can drive it in for a sticker, before the light comes on again. First of all, I would never do this if the code was somethiing that really needed to be fixed. But in my case it's a code that doesn't really mean much and would require dropping the fuel tank and removing / replacing the fuel pump or fuel pump sensors to fix. That's probably a $1,200 repair.Result, my gas gauge doesn't always work and I use the odometer to know when I need gas. I can live with that.Anyway, I've used this two years in a row to get a sticker. Sometimes it takes driving the car on a few occaisions for 50 or 60 miles. So it eats time, as it is not always successful on your first attempt. This is not a function of the tool, but more of a function of your car's computer.As you're driving you can see the tests happening and you get a green check mark in the app when each one is completed. Please note that in certain states you can have 1 failed emission code and still get your sticker. It's usually the catalyst that takes the longest to turn green. Once it does the app shows that the vehicle is ready for emissions testing. This usually takes 50 or 60 miles, at least.There are many forums that tell you how to specifically drive your vehicle for the quickest and best results. So I won't cover that here.The kicker is to get it to the station after all the codes clear, but before the computer finds the fault again. In my case this means NOT shutting the car off. If I do, and then restart it again, the light usually returns and I've wasted a couple hours of my time.So if you are going to use it for this task, just know that it isn't necessarily quick and easy. It takes time and you need to tell your mechanic not to shut the car off before testing.As I mentioned, all this being said, it has worked for me two years in a row and saved me from an unneccessary $1,200 repair bill.Hope this helps someone.
