ArtiDiag 900 Lite is a full-system diagnostic tablet for DIY mechanics. It reads every module, shows live data, freeze frames, and also performs bi-directional tests. It is not a coding tool. It is not made for deep adaptations.
It is mainly for people who want something much stronger than a basic engine reader or ELM327, but still cheap and simple to use. If someone needs coding or heavy multi-brand service work, tools like Kingbolen K7 or Mucar VO7 are better choices.
Test Results on Real Cars
I tested it on real cars.
Cars tested
• Toyota Corolla (2022)
• Mercedes E400 (2017)
• Mercedes S500
• Several other used cars during inspections
Scan speed was very fast. On the Corolla it scanned 33 modules in seconds. A full scan of this size on Bluetooth dongles can take ten minutes or more. Here it was done almost instantly.
Diagnostics worked on every modern car I tried. Full system access, reading and clearing codes, freeze frames, and live data all loaded without errors. The live data layout is clean, and you can graph multiple sensors at once. Recording works well too, including full screen recording.
Bi-directional tests worked in all modules that supported them. I was able to run the cooling fan, wipers, horn, doors, windows and other components straight from the tool. Everything responded quickly and without communication issues.
Used-car inspections were the strongest part. On the Mercedes E400 with around 70 modules, I found a mileage difference: about 280,000 km on the dashboard but 300,000 km stored in one module. On a 2017 car this is a clear red flag. Combined with suspension issues found by a colleague, the buyer negotiated a 6000 € discount. This is exactly why full-system tools are so useful when checking cars before buying.
The tool behaved stable. No app crashes. Google search icon helps beginners find fixes quickly. Wired connection is optional and the Bluetooth VCI stayed stable the whole time.
