TOPDON AD500 OBD2 Scanner - Engine ABS SRS Transmission Diagnostics

The TOPDON AD500 (also sold as the ArtiDiag500) is a handheld scan tool that goes past a basic code reader. It runs full OBD2 generic functions plus four-system diagnostics on the engine, transmission, ABS, and SRS modules, reading and clearing fault codes and pulling live data streams. On a transmission job that means you can watch trans fault codes, verify a solenoid or speed-sensor DTC, and clear the code after the repair without a trip to the shop.

Live data shows up to four PIDs at once and can be graphed, stored, and played back, so you can chase an intermittent code while the vehicle is running. AutoVIN reads the VIN and pulls the correct vehicle so you are not guessing at the make, model, and year, and a built-in battery voltage readout flags a weak battery that throws false codes.

Along with diagnostics it handles six service resets: Oil light, Steering Angle Sensor (SAS), TPMS, Battery Management System (BMS), Electronic Parking Brake (EPB), and throttle body adaptation. That covers most of the relearns you run into after a fluid service, battery swap, or brake job.

Coverage spans 67+ car brands and 10,000+ models in 12 languages, and updates are free for life over Wi-Fi, no SD card swapping. Hardware is a 5-inch touchscreen with physical buttons, 2GB RAM, 32GB storage, and a 3350mAh battery, running on Android 11.
