Outstanding Bi-Directional Tool
For the better part of a month I have been using the Topdon ArtiDiag 900 Lite every day.I diagnose vehicles will many different scan tools:Dealer Laptops $3000 annual subscription (each)Snapon Zues $7000 initial purchase, $1000 annual subscriptionI gravitated towards this scanner for the following uses:Grab and goCompactQuick Vehicle Resets like : battery and throttle position sensor relearnsQuick Clear all computers after serviceQuick Maintenance modesParking lot diags outside the shopThe Topdon Artidiag900lite lays in the top draw of my roll around cart, and takes less space then a set of sockets. This makes it easy to perform all scans on every customer car that enters the shop, and I can instantly send the scans to customers or service advisors.The Topdon Artidag900lite performs the best during routine services and post maintenance. Dealer tools are not wireless and you have to stay with the tool in the driver seat, using the Topdon Artidiag900lite I can wirelessly monitor the progress of updates, reprograms, and module resets. This adds a new level to multitasking.The wireless range of the Topdon Artidiage900Lite really shines when performing “Bi-Directional” support. The ability to wireless walk around a vehicle and command components of the vehicle to activate and/or move is a game changer. This feature paid for the tool in one diagnostic visit.Example 1: Customer Stated there is a rattle at idle and after engine start. Normally this would require the need for someone to sit in the driver seat, pressing the accelerator pedal, while I walked around the vehicle listening for a rattle. Now I can command the vehicle to increase RPM, how I want it, to the exact number. Using a car lift, I raised the vehicle and walked around the exhaust shields as I remotely adjusted the engine RPM.Example 2: After replacing a transmission assembly, you need to perform a transmission relearn for the Transmission Control Module (TCM). The Topdon Artidiag900Lite had no problem handling this, with a dealer tool I have to sit in the driver seat and monitor the temperature levels during warmup. Now I can wireless monitor the temperature levels while I clean up my area and put away tools.The resourcefulness is unquestionable. Community Shop Scanners are never returned or found dead on someones toolbox. Or when I’m in position of a Community Shop Scanner, another tech will be bothering me for it; because they cannot find the other community shop scanner. The affordability of the The Topdon Artidiag900lite has made all the routine tasks of a Dear Scan Tool faster and dramatically less stressful.Datalogging with the Scan tool is easy to set up, record, and save for future playback. For the first time the table hardware is more powerful than the software; usually it’s the other way around, and the product suffers with every update. The table screen is sharp and easy to see from any direction, the HDMI out port is a great edition, for hooking up to monitors. Other ports like USB A and USB C are a great addition for third party devices; bore scopes and thermal imagers. The Topdon Artidiag900lite also has a screen capture button hot keyed at the bottom for quick pictures of the screen.Overall this product is a must have for beginner mechanics and expert diagnosticians.The Topdon Artidiag900Lite is priced perfectly and offers more support than it’s overpriced competitors on the tool trucks.I would recommend this tool to every mechanic, technician, and DIYer.

Worth every penny!
Before I purchased this, I had been running handheld scanners of all types. Always wanting a bidirectional, but unwilling to part with thousands of dollars. Received the item quickly. It comes in a nice protective case with all included cables and documents.First thing I used it on was my DD Silverado that I’d been having strange electrical issues on for a few years now. Plugged in the device, it synched up with the tablet quickly, read the vin in about five seconds (reads newer vehicles quicker), and started the scan. All told it took less than five minutes to roll through the 28 different tests on my truck. Was able to pick up the interface and using the device quickly, pulled three extra dtc’s my old scanner never saw. Ran live data, and saw that cylinders 2,4,6, were all misfiring, and found out it was due to a new O2 sensor that had decided to quit. Was able to monitor my 5v sensors and see that my ect sensor was getting intermittent voltage. Literally took less than 30 min with this device to trace down what had been nagging me for a couple of years.It runs android iOS, has chrome for a browser. Once it is connected to WiFi everything is seamless, any question I had while using it were all easily answered through the systems help function. It has a cameras for scanning vins, plenty of storage. It’s just a great tool. I rarely am happy about anything I receive any more, always seems like I am reduced to just dealing with a products shortcomings.This unit is bidirectional, so you can run individual system tests to determine failure. There is so much more it can do, I still haven’t even cracked the surface of its capabilities.Got it on sale $150 off. Even at full price it would still have been cheaper than the three other scanners I’ve had over the years, plus throwing parts at what I thought the problem may be. Zero complaints. Worth every penny.Anyone who works vehicles more than they want to would benefit from this greatly.

Easy, Fast, Great Tool for DIY Shop Repairs
Easy to use, powered right up and quickly went to work diagnosing the issues on a 2007 Ford F350. Local shop was over a week out for diagnosis and several to start work on repairs. Got this in overnight, ran it, ten minutes later found out the issue was a $40 part that took 10 minutes to swap out. Durable unit, nice rubber molding/case to prevent knocking off work area or a mild drop. Screen is responsive, Bluetooth worked from cab to front of hood and sitting in a chair just outside truck reading and rescanning. Bidirectional control a huge plus for unit. Gives a near professional feel and even emails the report of errors it finds. Buy it, wont regret it for DIY shop repairs.

Highly recommend. Best scanner I have owned.
I would give this scanner six stars if an option was available. Have been using multiple different types of scanners over the years as a shade tree mechanic, but wanted one that was wireless and bidirectional. Thanks to the folks at Royalty Auto and their video reviews and recommendations, I decided on this TOPDON. Glad I did! Quality is great, solid case and display. OBD2 Wireless Plug-in adapter stores neatly in the back of the scanner and works flawlessly. Unit was easy to do initial setup and software updates. Actually first used it on my neighbors BMW 740l to do a service reset and new battery replacement and registration in the system. (Didn’t know that was a thing!? lol) He and I were both blown away at how quickly this scanner auto recognized the vehicle and established comms. It took no time to reset his service intervals and do the BMS battery maintenance/replacement systems update. Simply blown away. Plugged it into his GMC Yukon Denali next and it just as quickly went through that vehicle’s systems. Even has the option to adjust the air ride suspension settings with this scanner. Absolutely blown away for the capabilities at this price point. It runs Android 11 and can be used as a regular touch screen tablet as well, along with having a camera. Mind blown. Don’t hesitate to buy if considering.

El hardwares es espectacular, de lo mejor que he visto, pero el software es muy limitado. No incluye muchas marcas ni opciones del modelo inferior. El fabricante no permite actualizarlo.

Bought this basically for BMS (Battery Monitoring System – new battery registration) for my Range Rover velar. Worked perfectly.Having bought the battery myself + the diagnostic tool, it practically paid for itself, saving me amount I would have been charged at the dealership, plus I get to keep the tool for future use. Definitely worth the money!Very easy to setup, wifi connectivity.
