4-System Diagnostics
The AD500 goes beyond basic OBD2 by offering in-depth testing for four key vehicle systems: engine, transmission, ABS, and SRS. It reads fault codes and data streams for each system, helping you pinpoint issues that a standard code reader might miss. The tool also visualizes real-time data in chart form, which simplifies complex information for storage and future playback. This feature is particularly useful for DIY users who want to track down intermittent problems or monitor system performance over time.

6 Reset Functions
One of the standout features of the AD500 is its six maintenance reset functions. These include throttle adaptation, oil reset, SAS (steering angle sensor) reset, TPMS (tire pressure monitoring system) reset, BMS (battery management system) reset, and EPB (electronic parking brake) reset. According to the manufacturer, these functions help align the throttle, battery, tires, and brake pads with your vehicle, and can turn off the oil light after an oil change. For those who perform routine maintenance at home, these resets can save a trip to the dealership.
Multiple Functions for Efficiency
The AD500 features Smart AutoVIN, which automatically identifies the vehicle’s make, model, and year to streamline the diagnostic process. It supports up to four live data streams simultaneously, making it easier to monitor multiple parameters at once. Additionally, the tool offers online diagnostic feedback to assist with tough repair operations, and real-time car battery voltage monitoring to help identify potential defects. These features are designed to make diagnostics more efficient and user-friendly.

Wide Vehicle Coverage
According to the manufacturer, the ArtiDiag500 supports over 67 car brands and more than 10,000 models, covering most vehicles worldwide. It is compatible with cutting-edge CAN FD protocols, which means it can work with modern vehicles including 2020+ GM and Chrysler models. The scanner also supports FCA AutoAuth (official Secure Gateway access), allowing it to stay up to date with newer models from Chrysler, Jeep, Fiat, and others. This broad coverage ensures that the tool remains useful across a wide range of vehicles.
Upgraded Hardware
The AD500 is equipped with a 5-inch screen that provides a clear display, and it combines a touchscreen with physical buttons for user-friendly operation. It runs on Android 11 and has 2GB of RAM and 32GB of ROM, providing ample storage for diagnostic data and future updates. The 3350mAh battery is designed for long-lasting use, and the ergonomic design makes it comfortable to hold during extended diagnostic sessions. The package dimensions are 10.2 x 8.3 x 2.4 inches, and the device itself measures 9 x 1 x 5 inches.

The TOPDON AD500 is ideal for DIYers, car enthusiasts, and home mechanics who want a capable diagnostic tool without the complexity of professional-grade scanners. It suits those who own multiple vehicles or work on a variety of makes and models, thanks to its wide vehicle coverage. It’s also a good fit for those who perform regular maintenance like oil changes, brake jobs, and tire rotations, as the reset functions can save time and effort.
