AD800BT 2 OBD2 Scanner, 2026 Bidirectional Scan Tool, Function as AD900 Lite AD Pro, All System Automotive Diagnostic Scanner, Active Test, 28+ Reset Service, FCA Autoauth, 2 Years Free Update

I’ve used a lot of scan tools over the years, and the ArtiDiag800 BT 2 honestly surprised me with how capable it is for the price point. Right out of the box, setup was simple and the Bluetooth connection was solid. Not having to deal with a cable hanging from the dash is a bigger deal than you’d think—especially when you’re moving around the vehicle running tests. Where this tool really stands out is the diagnostic depth. This isn’t just a code reader. I’ve been able to run active tests, control components, and actually diagnose issues instead of guessing and throwing parts at a problem. Full system scans are quick and it pulls data from everything—ABS, SRS, transmission, BCM—you name it. The bidirectional controls are what really make this tool worth it. Being able to command things like fans, actuators, and other components saves a ton of time and takes the guesswork out of troubleshooting. For anyone doing real mechanical work, that’s huge. Vehicle coverage has been solid too. I’ve used it on a mix of domestic and import vehicles without any issues, and it handles newer systems like CAN-FD, which is a must if you’re working on newer models. It’s also got a ton of service functions built in—resets, relearns, maintenance functions—basically everything you need for most day-to-day jobs. Now, it’s not perfect. The battery life is decent but not amazing, and the tablet itself feels a little basic compared to higher-end units. Also, this isn’t a replacement for OEM-level programming tools—you’re not doing ECU flashing with it. That said, for what it’s designed to do, it absolutely delivers. Bottom line: If you’re a serious DIYer, side-work mechanic, or even running a small shop, this tool hits a sweet spot. It gives you professional-level diagnostic capability without the professional-level price tag. It’s one of those tools that pays for itself pretty quickly

My husband loves this computer. He has already used it on his work car. It found the problem right away. Good price. Reads codes very well. The battery last long for what you need. Easy to use and understand.

The TOPDON AD800BT has proven to be a highly capable diagnostic tool. It provides full-system diagnostics across critical vehicle systems, including engine, transmission, ABS, SRS, TPMS, BMS, and more. The scanner delivers detailed fault codes along with real-time live data, allowing for fast and accurate troubleshooting. AutoVIN functionality automatically detects the vehicle’s make, model, and year, streamlining setup and improving diagnostic accuracy. One of its strongest features is the extensive set of 28 service functions, such as oil reset, SAS calibration, DPF regeneration, TPMS reset, and throttle adaptation—capabilities typically found in dealer-level equipment. The included Bluetooth VCI enables wireless operation with a reliable range of up to approximately 33 feet, adding flexibility during diagnostics.

Super simple to use the connectivity works great it’s literally plug-in play setting up an account is super simple. Downloading updates is a little buggy. Make sure you do one at a time if you try to mass download them, it glitches out and takes forever. All the functions that I used work properly, it identifies the vehicle properly, all the test functions work if it says it works for that vehicle. Honestly, my only downside is the immobilizer. So far on each vehicle I’ve used it on, it said it was incompatible so if you’re buying this to program keys, I would not choose this as it has very little compatibility. Other than that it works exactly as advertised and for any home mechanic or beginner at a shop, or even a professional that just wants something simple to get everything done this is a great option.

Great scanner I love how easy to use and compatible it is with many vehicles I also enjoy the many features such as the many maintenance systems available.

This is my initial review for this TOPDON ArtiDiag800BT OBD2 Scanner and I'll continue updating it as I use it. I love the design and the pull up scanner attached to the handle of the scanner, it's very easy to store, so you feel safe that you won't lose it, also love the little protective case that it comes with, great accessories. In my opinion this wireless OBD2 scanner works great and very accurate, Already been using it alot. Just yesterday I had an error code. After researching it was either the thermostat sensor or the pump. Tried both and I figured it was the thermostat since I can see the live data, on my topdon OBD2 screen, I could watch the temp before and after replacing the unit sensor. Great OBD scanner, with very big and easy to read screen, the software is built over android so it's easy to update and navigate and if there is any firmware needed I won't need to go through the headache like my old obd's, that you have to do to install new updates through usb stick and all that headache, it might feel a bit pricey but then when you use it and go through the setup process and their easy, straight forward menu system, you'll understand why. It got every car you can think of in the market right now. Overall, very good quality OBD Scanner with so many features for a great price and I recommend it. P.S. I hope you like my little video showcase, Don't forget to smash the helpful button, If you liked my video review.

After watching multiple YouTube videos of mechanics and the like promoting the TOPDON ArtiDiag800BT diagnostic scanner, I thought it might be a great holiday gift to give myself. My first problem started once I got it, registered it, put in the activation code, and started downloading the programs I wanted to use. (As a caveat, you must have internet connectivity for this tool to work, period. Even after you've downloaded the different software on it, you will still need to be tethered to wi-fi. At least, that has been my experience.) It will not work in the field, for example, if you don't have wi-fi access. It simply freezes and is stuck on "loading," but loads nothing. When it is connected to wi-fi, it does work sometimes depending on what screen you are on. If you are running the OBD2 general program, then you can get away with a successful scanning of the codes, most of the times. If you are trying to do a full health scan, then you may get a frozen screen about half the time. Let's talk about some of the features it boasts and learn whether they work. I purchased this tool with the intention of using it after completing some work on my BMW X3. Specifically, I was changing the eccentric shaft sensor (if you own a BMW with this sensor, you know its a commonly known failing sensor) that takes removing the valve cover to get to. After removal, the dreaded "valvetronic, eccentric shaft sensor 2A31, 2A32, and 2A47 codes needs clearing with a capable scanner. This tool takes you into that very module and attempts to clear the code. It will even tell you that the code is cleared, but it actually does not clear the code. They all come back. (Of course, if you are doing this job, do not ever use an aftermarket sensor, or the so-called OEM brand on eBay or Amazon, get an original one from the dealership. You'll thank me later.) The tool also does not reset the oil light in the BMW. In fact, the tool tells you that you need to do this manually "on car," which I already knew how to do. It does not clear the transfer case "wear oil" code, even if you go into that exact module to do so. It also did not reset my steering angle sensor to zero after I've changed it. Some positives are that it will read all your car's codes and that it is quite thorough when it complete the health check scan (when it decides to work fully). For the price tag and my experience of having it only read the codes that my other Launch diagnostic scan tool does, but only cost 1/4 of the price, I would say to stay away from this tool until the company finds a way to load all the programs onto the hardware so you can use it wherever you go, and check on their reset functions. Maybe it works great on everything else, except BMWs.

Fully recommend this scanner for any mechanic. Even if you have a scanners get this one too it helps a lot it's nice portable affordable

最初のインストールに少し時間が掛かるけど、終われば日本語で操作しやすく便利が良い☆当方は此に延長ケーブルで手元で操作してますが大変良い。リセットも簡単、終診断で故障箇所も分りやすい。取り敢えず気に入ってます。

車種が幅広く、プロでも使える。 またアップデートが無料て、コストパがいい!

全システム診断、且つ、生涯無料アップデート対応。ダイハツにも対応。素人のDIY用途としては充分な機能かなと思う。

通信も早くてとてもいい物だと思います。 上を言えばキリがないですが、このOBD2で、十分だと思いました。 ただ、もう少しストレージが多く欲しかったです。2年間の無料期間の更新で、全てを更新してしまうと、確実に足りなさそうです。

街のバイク屋さんをしています。 バイクの車検で当店をご利用頂くお客さんから車の車検もちょいちょい受けることがあり、今まで使っていた診断機が古くなったのでプライムデーで買いました。 故障コードの読み取りとかリセットも出来ました。 買ったばかりなので国産車数種類とBMWのミニに使いました。 うちの代車で使っている日産ノート（E11）は繋いだだけでは車体番号の読み取りは出来ず、手動の車体番号を入力しても認識できませんでしたが、何度かトライしているうちにE11を認識したようです。 BMWのミニはエンジンチェックランプ点灯の状態でつなげたところ、自動で車体番号を認識してエラーコードの判別が出来ました。 結果的にO2センサーで、フロント側と診断していました。 一旦そのままエラー消去をしたらエンジンチェックも消えました。 現在O2センサーを取り寄せ中なので、交換出来たら再度つなげる予定です。 うちみたいにとりあえず車検に持ち込む前の検査程度であれば十分使えそうです。 メーカー専用の診断機は高いし、数千円程度の読み取り機では不十分なのでそこそこ使える診断機として使うには良いと思います。 購入前にもう一つ上のグレードの診断機も考えていたのですが、更新料がかかるとのことでやめました。 現在お店で使っているバイク用の診断機も年間のサブスクで３～４万かかっているので、バイクほど使う機会は少ないため更新料がないこちらの機種にしました。 故障コードとかはメール送信できるので、メモする必要もないのもよかったです。 日本語表記で感覚的に使えるので気になる方は買っても損はなさそうです。
