- [2026 Top-Tier Hardware and Software Upgrade]: Topdon ArtiDiag900 Lite scanner has enhanced hardware and latest features, including Android 11.0, 5x faster CPU, 10000mAh battery for 12 hours of continuous operation, stable wireless diagnosis with Bluetooth 5.0, 8-inch touchscreen. Added bi-directional control, wireless diagnosis, battery testing (optional), and DTC repair guide
- [TOPDON Bidirectional Scan Tool]: This bidirectional obd2 scanner sends commands to the vehicle's ECU for active testing, enabling users to accurately and quickly locate faulty components such as injectors, coolant pumps, windows, wipers, headlights, mirrors, etc. The bidirectional control scanner is the ideal choice for workshops/automotive repair shops as it significantly reduces mechanic's diagnostic time.
- [Wireless Bluetooth Diagnostic Experience]: The AD900 Lite scan tool comes with a Bluetooth 5.0 VCI, supporting a wireless diagnostic range of up to 33 feet (10 meters), allowing you to diagnose without being confined to cables or tight spaces. Stable and fast wireless diagnosis provides a comfortable repair environment. It also offers VCI cables to increase connectivity options.
- [DTC Repair Guide Function]: Easily diagnose issues with your vehicle and receive guidance on repairs with the topdon scan tool's fault code definitions for all systems,maximize your diagnostic capabilities. This function is compatible with Chrysler
/Dodge/Jeep/Fiat 2010-2014 and expanding with continual updates,the AritDiag 900 Lite car diagnostic scanner is the must-have tool for any technician or DIY enthusiast. - [OE-Level Full System Diagnostics]:AritDiag900 Lite full system diagnostic scanner can scan ALL available modules(Engine, Transmission, Airbag, ABS, ESP, TPMS, Gateway, Steering, Radio, Air conditioning, ect.) to✔read ECU info, ✔read/clear codes, ✔view live data stream, ✔retrieves freeze-frame, ✔perform active tests, and more. With just a simple click, it provides you with accurate and in-depth diagnostics.
/
- Bi-Directional Control, Quickly Locate Problems: Turn your phone into a professional diagnostic tool. You can send commands from your phone to the ECU to test injectors, cooling fans, headlights, A/C clutch, windows, wipers, and more. See which one doesn't respond. Helps you quickly locate the problem and save time. No need to tear things apart, avoid blind disassembly.
- Flexible Subscription, Choose Advanced Features as Needed: TopScan Lite provides free-for-life access to core diagnostics, including full system scan, code reading, performance tests, and repair information. After purchase, advanced features (bi-directional control, service operations, live data, code clearing, and AI functions) are free-for-the-first-year. After the first year, if you want to use advanced features, you need to subscribe on a monthly, quarterly, or yearly basis. As new models and reset functions are updated, the tool will also be continuously upgraded.
