ELM327 Bluetooth OBD2 Scanner for iPhone & Android, Wireless Auto Check Car Fault Code Reader for All 1996 & Newer Gasoline Vehicles - Blue

This is pretty cool. It is a simple plug that plugs into your OBD2 port (right under the dash). Several free apps are available in the app store (IOS) to choose from and takes two seconds to install the plug, connect via blueetoooth, and view diagnostics.It will not verify or resolve TPMS issues. You need to buy something more expensive and I still don't know what that is yet.I don't have a check engine light on but if it was on, this would help me understand what is happening with the car.

I can’t give it zero stars so 1 will have to do. Absolutely will not connect to anything. I have tried the password that comes with it and all the common passwords. I have tried several different devices as well. If you want a little red night light that glows from your obd2 port then this is great, if you want anything else find something else. I have had several of these adapters in various styles and while none of them seem to last long they do at least work when you buy the others.

The check engine light goes on/off randomly on my Jeep Grand Cherokee for years. I’ve had 3 mechanics look at it and none of them can figure it out. The last one to look at it told me to get an OBD II reader and clear it out when it comes on so I got this one. It was easy to use, read the code and then cleared it for me using my iPhone. It’s been a couple weeks now and the code is still clear. + I have the screenshot of the code readings for my records.

It does what it is supposed to do. I wish it would work with more apps on IOS, other than that 4 stars

It's a pity that the diagnostics didn't work for me. But the seller is very good.

I’ve read the instructions multiple times and have tried multiple options pertaining to my vehicle and still will not connect to it. It will connect to my phone but as far as reading the ecu it doesn’t connect.

Has saved me hundreds and hundreds in diagnostic fees, but also has helped alongside the road when my car went into limp mode and I didn't have to do extra driving to an auto parts store for diagnostic. Very accurate and gives you a lot of info about your vehicle that most don't give.

There's a lot better units than this one. I've had problems with getting this to connect, then read.I'm using torque pro on an android head unit. This fails my tests, I'm no longer using it, got something else.
