Xtool AD20 Pro Car Diagnostic Tool is a powerful, pocket-sized Bluetooth 5.0 diagnostic tool that transforms your smartphone into a high-end vehicle scanner. While many small dongles only read engine codes, the AD20 Pro performs an In-depth All-System Scan, accessing modules like ABS, Airbag (SRS), Transmission, and Body Control to provide a complete health report of your vehicle.
Designed for the modern driver, it combines professional diagnostics with innovative "Smart Driving" features like a Head-Up Display (HUD) and trip analysis, all with lifetime free updates and no subscription fees.
All-System "In-Depth" Check: Unlike the standard AD20, the Pro version scans every available electronic module in the car to read and clear manufacturer-specific fault codes.
Oil Light Reset: Allows you to reset the maintenance counter yourself after an oil change, saving you time and money at the repair shop.
Battery Health Monitoring: Performs real-time voltage testing, generator output checks, and cranking voltage analysis to ensure your battery never leaves you stranded.
Smart Dash (HUD Mode): Projects critical engine data (Speed, RPM, Coolant Temp) onto your windshield using your phone, keeping your eyes on the road.
Driving Behavior Analysis: Tracks sudden braking, rapid acceleration, and sharp turns, providing a safety score and trip logs to help optimize your fuel efficiency.
Performance Testing: Measures 0–100 km/h acceleration times and monitors engine load to evaluate your vehicle's true power.
