OBD2 Scanner, WiFi Car Code Reader Check Engine Light Diagnostic Scan Tool for iOS and Android

This Foseal OBDII Scan Tool does exactly what it says - it plugs into the OBDII port in your vehicle, provides a private WiFi connection to your Smartphone, and allows you to use any of many compatible OBD apps to analyze vehicle data, performance stats, fault codes, and even (if the app allows) reset / clear errant fault codes (eg. O2 sensors in performance vehicles).On my iPhone, using the outstanding OBD Fusion app, the Foseal scan tool connected quickly, showed all vehicle data, and allowed fault code resets as promised.Of course - since this provides a private WiFi connection, if you want to watch vehicle performance while driving (RPMs, etc) then you won't have network connectivity for your other apps, streaming music, etc. This is just a limitation on how these WiFi scanners work. It's also why they are less-expensive and more reliable than their Bluetooth counterparts.In my vehicle, there are 2 "OBDII" ports - one of them is a standard OBDII port, and the other is reserved for the proprietary manufacturer diagnostic harness. If your vehicle has more than one port, make sure you connect this to the correct OBDII port, or it will not connect (even if the light is powered on).

I’m a DIY guy. 2008 Toyota 4Runner. This is a great product. Worked exactly how advertised. Saved me $2000 and I learned a TON about my vehicle in the process.3rd party YouTube videos with this product on trouble shooting made this a breeze.This does take willingness to learn, note taking, and reading if you want to use this as a DIY car mechanic tool. This is not a problem solver, it’s a tool. One of many you will need to work on your carIf you aren’t willing to do the mentioned above, this will most likely not save you any moneyThis was extremely easy to use, has a great user interface via the app. I did purchase the extras for my specific vehicle. Totally worth every penny.Don’t bother spending extra money on a more expensive diagnostics tool unless you are getting the multi thousand dollar tools from snap on etc

You have to connect your wi/fi to the device to get it to work. Main problem is the apps Dont work in the background so if you use the phones gps you'll be missing some data.

I had the dreaded "check engine" light appear on my 2014 Equinox. Since that did not offer any specifics - good or bad. I ordered this scanner at a bargain price, not one that cost hundreds of dollars. It arrived promptly in good condition with comprehensive instructions. Rather than include a computer at this price, it establishes a wifi connection to my phone. I got a fuel burning lean reading with the software included at no charge. I then splurged for the $4 upgrade to the software with much more comprehensive software. Nothing new showed up and I saved hundreds by not having to take the car to the garage! Highly recommend! You do not have to be a mechanic to use - it's all plug and play from the car interior.

Let me preface this review with 32 years of engineering experience, with a Masters degree in engineering, have taught college level engineering, and several years as a racing mechanic in my youth. Usually I am pleasantly surprised with something that works perfect, out of the box, especially if it is so well designed that do not even need the manual. Thus I am not too concerned when I need to read the manual or reach out for technical support on a device. How I rate a device depends a big part on both the usability AND the quality of support. In this case Foseal's support STINKS!!!!My 2011 Dodge Charger, R/T, AWD, Hemi had a known issue. One, or more of the speed sensors were not working and the trouble code had been confirmed on my dash as well as confirmed on a professional mechanic's scanner. I have been looking for a less costly scanner that I could use on my smartphone or tablet. Foseal SEEMED to be a good choice based on the reviews. I was doubtful based on the price point but willing to give a try.....The setup/install was NOT 100% plug and play but not too complex either. I did have to read the instructions though. I decided to use OBD Fusion and Car Scanner as the software interface on an iPhone 6 Plus. Once the device and my phone connected both apps displayed near real time "gauges" and such. I could see RPM, temps, speed, etc. Thus if that was all I wanted I would have been happy.But most of us would expect, that if there was something wrong with the vehicle, it would let us know what the trouble code(s) was(were) and in, hopefully, semi-plain English. Instead this device, on BOTH apps gave my car a clean bill of health. WAIT...WHAT? This is why I decided to test this on my car...BEFORE I repaired it. My first thought was I needed to make parameter changes in the software. After two hours of research and several changes...still ZERO trouble codes, in both OBD Fusion and Car Scanner.So I sent a polite request to Foseal's support email (could not find a number to call or chat) on 5/24/2019. I asked they help me determine why it gave me a "false positive" clean bill of health and assistance in trouble shooting it. I waited six days, checking both my inbox and Junk/span folders daily. ZERO RESPONSE. So I sent another email with the previous one included on 6/1/2019. In this email I gave them 48 hours to respond before I would give a negative review and request a refund. Today is 6/3/2019 and still no response.Thus I give them a failing grade on both their device for its main purpose AND their WORTHLESS support.

Using Alfaobd it will not connect to Climate Modules in Ram, Dodge, Chrysler, ect. It does the basic stuff.It WILL connect to Toyota and read the PID first trans temp.
