ANCEL BD200 OBD2 Scanner Bluetooth - Code Reader & Check Engine Diagnostic Scan Tools with Car Battery Test, Exclusive App On iOS & Android, Wireless OBDII Adapter Works for 1996 & Newer Vehicles

Found direct source to all my problem’s. Must have. Literally takes out all of the chasing. I’m over impressed with how well it performs for the price along with the many other features it has. Simple and easy to use scanner/code reader. Easy Bluetooth connectivity. Anybody who has ever chased down misfires knows how much of a guessing game it can be but this here is a game changer

Solid little unit. Fits right into the OBD port on my GMC vehicles and using the Ancel app I can easily view error codes showing up on my dashboard and know what action may be necessary. In particular I was getting a "Check Engine" light on my 2018 GMC Canyon, and checking the error code was indicating a fuel vapor recovery issue (either a bad sensor or loose gas cap, which doesn't exist on my truck). Able to clear the error code easily.The other diagnostic functions on the unit/app are very useful. 5 star investment for my toolbox.

It paired up easily via Bluetooth, and worked immediately when scanning trouble codes. I had no trouble accessing any of the features or doing any of the performance tests. Some of the data on the features dashboard are for more advanced mechanics, but I was able to muddle through them. I don't know what a few of the features are for, but I will get to know them in time. The app has a help function, and you can also send feedback to the company if you have a problem installing or connecting it. Trouble codes are defined for you, so you don't need to look anything up, and you will know what the problem is immediately. "Pending codes" are also displayed.My only gripe about this device is that none of the dashboard functions, including DTC history can be accessed in the app unless the device is plugged into the vehicle. I wanted to go to my mechanic and show him what the device actually read. When I got to the shop and opened the app, all it said was, "Device not connected"! For this reason alone, I give it four stars. So for all intents and purposes, the app itself is useless if you aren't actively using the code scanner. It should at least retain the trouble code logs! Also, while you can leave the device connected when you are doing trip performance functions, you should not leave it plugged in permanently.

Bought this one because it will auto connect to your phone. The app interface is initially confusing but gets better with time.

NOT FOR HYBRIDSThis device is listed as "compatible" with Toyota Prius. That's a bit misleading, it only reads codes from the gasoline engine, not the complete engine including the hybrid system and battery. In other words, it's useless on a hybrid vehicle. It did not read codes from the chassis, TPMS or anything else either.LOCKED TO APPThat wouldn't be such a problem if it would work with 3rd party apps for the other systems, but it is locked to the app it comes with and the phone will not recognize it to connect. No idea why that is necessary, they only gain by opening it to other apps. Go figure.As for the app itself, it's nice. Connects quickly and easily, it's easy to use. Builtin DTC lookups. Too bad it doesn't work on my car.

so convenient I bought another one :)

The ANCEL BD200 works perfectly! Hooks up to my iPhone XR every time. Have used it in all of my cars (see below) and it has helped with showing, researching and clearing trouble codes. Shows LOADS of info in real-time. I send screenshots to my mechanic and he helps me out. Gives more info than OBD readers over $100 at the parts store. (I actually ended up buying a second one so I could keep one with me on trips).My cars:2007 Honda CRV2003 Honda Civic2005 Chrysler Town & Country2010 Mercury Milan

I bought this thing in a week and a half ago, just used it on 5/12/2021, followed every piece of what seemed easy instructions, connected fine the first time, seemed to do a thorough scan, was able to get the diagnostic report, then noticed some clicking noises consistently tapping somewhere in my Mercury Mountaineer that i never heard before, suddenly my dash lights flickered and the device disconnected ( Car battery strong before device plugged in ), i turned my car off the on position and refollowed the instructions to reconnect, Turned to on position, tried to reconnect the app to the Ancel device (nothing).. So after frustratingly trying over and over hitting the "connect" in the app, the power in my SUV died again, this time even worse, i tried to put my windows back up because i got tired of trying and there was absolutely no power to get my windows up..This device COMPLETELY drained the life out of my poor battery in a car i already had issues with.. So this thing gave me an additional problem to resolve..I will be going to only manual plug in from here on out, the Bluetooth crap is just not the way to go..I'm relentless so i will try one more time before i return this thing.. i also noticed another thing, it is complicated to get to your past diagnostic checks, you have to basically stop it from auto connecting then go to the failed check and tap on the very small very difficult to locate icon at the top of the app and look for your previous check.VERY POORLY DESIGNED APP AND DEVICE!!!
