Does everything a DIYER or semi professional could ask for at a reasonable cost. Finally found the perfect balance. I have a Topdon battery tester too and would be happy to buy other products based on my experience.

This scanner is pretty awesome. opened it up and it had a software update to complete which it finished quickly. I plugged it in to my f250 to see how it worked and I was impressed with how quickly the Bluetooth receiver connected to the scanner. It’s a pet peeve of mine when Bluetooth devices don’t connect on the first attempt. The next thing I was impressed with is how many things it can monitor. Must have been hundreds of options from engine hours and number of ignitions, to throttle position and torque. I really only bought it for diagnosing problems but will probably mount it in the truck on long road trips with the trailer to better monitor the trucks performance. Another thing I am excited about is using this before purchasing a used vehicle. I feel like there is no hiding from this thing. Overall I am giving this 5 stars for its user friendly interface, sturdy construction, and it’s capabilities. I will update when I use it to diagnose a problem.

I started with the Autel Maxi200 Bluetooth diagnostics tool, and it was serving my needs pretty well for the most part until my Jeep needed both a Cam sensor and Crank Sensor replaced. After researching a bit, the ArtiDiag900BT had the exact service function I needed and a few more useful features that I could see myself using with other projects. I replaced the sensors, then it took less than a minute to perform the sensor relearn. The speed of this machine is insane, it reads the system information in seconds, the UI is very simplistic, easy to learn, and designed well. After browsing through the system menus more, you really learn the advanced capabilities this machine does that’s hidden behind a few safety prompts. It has updates daily for vehicle programs, and the system remains stable with no change to performance or speed swiping through any of the menus. Overall this is a product I would purchase over, and have already began recommending it to all my mechanic friends and family.

I decided I needed a Bi-Directional scanner so I can do more in-depth monitoring of my cars and more complex diagnosing. I watched many videos and saw the name Topdon and started looking at this model. It's a midrange scanner and exceeds what I need know but I know I will grow into it. One thing I wanted was a scanner that did in depth transmission diagnosis. These screen shots are from a 2017 Traverse and wow does it have a lot of modules this scanner can talk too. Another thing I recommend is get used to the menu system as I would find a test and then later not remember where I found it. The screen shots above show the path to get to the features I need. I see long term fuel trim is off a little and I need to investigate that. Maybe the air cleaner is dirty or worse and a rodent may have made a nest in the airbox and is messing up the fuel trim. The blutooth wireless connected quickly with the scanner and worked flawlessly. There is lots more to learn about this and I watched the Topdon Youtube video on the many features which helps me see the power of this unit. This unit feels well put together and not cheaply made. The only thing I see missing is a kickstand in the back to stand the unit up. You will be impressed with this unit.

I talked to my mechanic buddy and he recommended the TopDon 900Lite bi-directional scanner. Absolutely love it. It even lets you reset the mileage in case you want to change your cluster and the mileage is different. I believe it will even let you program key fobs. My favorite part is its Bluetooth so you can plug in the adapter and take the reader to the engine bay.

This thing is awesome. First of all the Bluetooth dongle is a game changer. It’s so convenient to use without being tethered by a cord to the usb port. I am amazed at the coverage of makes and models along with the included updates. And the bi-directional abilities are second to none. I have not seen a more feature packed scanner at this price point. Definitely worth every penny when working with these modern cars and trucks.
