The XTOOL Advancer AD20 Pro is a wireless OBD2 code reader that pairs over Bluetooth with a free Android/iOS app. It reads and clears fault codes across all systems, not just the engine, and adds 10 OBDII tests, oil reset, battery check, DTC lookup, performance and trip analysis. Its AI assistant packages diagnostic results into plain-language analysis, which sets it apart from basic code readers. It suits DIYers and home mechanics on 12V cars who want deeper diagnostics without a shop tool; it cannot work alone and does not support 24V trucks.

The XTOOL Advancer AD20 Pro is a wireless Bluetooth OBD2 scanner and code reader. It works together with the Advancer app on an iPhone or Android device and cannot be used alone. It supports 12V cars only, not 24V trucks.
It includes all-system scan, engine light check, oil light reset, battery check, DTC lookup, performance test and trip analysis. The all-system scan checks for faults across systems such as the engine, powertrain, steering, brakes, safety and comfort units. It reads and clears error codes for all systems. Available functions vary by vehicle.
DTC lookup gives code descriptions and possible causes. The Smart Dash feature turns the mobile device into a digital dashboard that shows engine information, including projection onto the windshield. Trip analysis shows a route map, distance, maximum speed, revolutions, temperature and average fuel consumption. It also records rapid acceleration, sharp turns and emergency situations. The battery test checks battery voltage, generator output and starting voltage.
