CR720 OBD2 Scanner Battery Tester 2 In 1, OBD2 Scanner Diagnostic Tool For Car Check Engine Light Code Reader Scan Tool & 6V 12V Battery Charging Component Test EVAP Live Data For All OBDII Cars

Works on my 2018 F150 and did an ABS bleed after a master cylinder replacement on my Daughters 2009 Grand Caravan. It worked perfectly. Easy to use and automatically read the VIN and vehicle info on both vehicles

Came within two days. Works as promised. Easy, just plug in and turn the ignition key. Unfortunately the one car I own that has the check engine ligh on has some problem with the OBD plug. I think the wiring on the plug is damaged. My mechanic had an issue with it. The scanner works flawless on the other two vehicles we have. You can read a translation of the error code in plain English. No need to look up error codes on the internet. This Udiag is simple to use, no fuss and hassle with linking a phone or anything like this. Do yourself a favor and get this. You don't even need batteries. It uses the car power from the plug. Fully happy with the reader. Not so much with my 2006 VW new beetle with a broken OBD plug.Update: I had a fuse missing on the OBD power supply. The previous owner or some lazy mechanic probably "borrowed" the fuse for that circuit. Popped a new fuse in and the reader worked great. It showed me the code number and description of the error code. My other car actually gives more information through the reader on current status and such. The level of information depends hichly on the setup of the computer in the car. Nice thing is that the unit does not need batteries and gets power from the car plug. (hence the issue with my car and the missing fuse). I had ordered a similar unit before that works with the bluetooth feature of the phone and an app on the phone. That unit was faulty and I had to send it back. I always would get this standalone unit since it is really easy to use with little that can go wrong.

I like the large screen

I drive a 1998 Jeep Grand Cherokee Laredo. Being that it is older if I don't tighten my gas cap at least 4 extra turns, my check engine light always comes on. I use to have to go to the local auto store and have them read it and then clear it for me. Well yesterday is came on again and I'd had enough. I ordered this after reading amazing reviews and even paid extra to have in over nighted. I just got it and immediately went out and it is so easy to use! After watching so many people do it for years I knew right what to do. This told me the code, which I knew what it was, but it also told me that it was a small vapor leak. The other places have to look the codes up, and this tells me! It doesn't come with a charger, but luckily I have a million different ones and had one that works with it. This is an awesome thing to have when you don't want to have to go to either a mechanic or auto store to have it read. So convenient and easy to use! I'm a very happy 26 year old woman!

This works really well it also has extra features as long as it is compatible with the make and model of the car. They say to update it before trying it out. So I did that first just so I could check it out properly. Great little machine to have it’s notJust for looking up codes it does so much more. Sometimes all you have to do is follow the instructions on screen depending on the task.

The udiag OBD2 Scanner is a great instrument. I chose this model because it is capable of detecting a misfire. Not all scanners provide this test. The scanner saved me both time and money because it read that cylinder 6 had the misfire. This made finding a bad ignition cable quickly. It also showed the exact other part that caused the Check Engine to Light. For a very small price, the udiag OBD2 is the most valuable car repair tool I own.

This is a good, reliable reader that's easy to use. It handles both of the cars in our household without a problem and gives clear information regarding why that "Check Engine" light is on and can turn it off if the problem is a minor or sporadic issue.However, mine developed a problem where it would turn on and .... that's it. Blank screen. On a whim, I opened it up and noticed that the single ribbon cable on the circuit board had unlocked and come loose. After putting the cable back in and locking it, the unit worked like a champ.So, if you also get a blank screen in the future, check that ribbon cable before giving up.

Works well but did not come with any instructions.
