Which vehicles and systems the AD500 actually covers
We recommend the AD500 if you want four systems diagnosed: engine, transmission, ABS, and SRS. Unlike basic code readers that stop at check-engine lights, this tool reaches the modules that handle gear shifts, braking, and airbags, and it can clear fault codes and read live data streams from those systems.
The AD500 covers 67+ vehicle brands and supports CAN FD, which matters for 2020+ GM and Chrysler models and for FCA vehicles with the Secure Gateway. It also handles full OBD2 functions for emissions checks.

What it will not do
This scanner diagnoses and resets; it does not physically repair failed components or guarantee a vehicle is safe to drive. A code pointing to an ABS sensor, for example, tells you where the problem lives, not that the car is ready for the road. Use the live data and the reported codes to decide your next step, whether that is a repair or a visit to a shop.
Skip it if you expect a repair tool or a substitute for professional inspection.
It handles resets, not mechanical fixes.

At $146.99, the AD500 is $11.74 below the typical price over the last 90 days of $158.73. That is a 7% saving, and a straightforward discount for a tool that would otherwise cost you the going rate. If you need a scanner now and the full feature set matches your car, this is a sensible moment to buy. Features and specs are listed above; the price is current as of the check date.
What to confirm before you buy
You need an OBD2 port, which most cars have, but confirm your specific model on TOPDON's vehicle coverage page before purchase, especially if you drive a 2020+ GM or Chrysler product that uses the Secure Gateway. The AD500 bypasses that gateway, but coverage still depends on the model.
The AD500 runs on a 3350mAh battery and needs charging if it sits unused for long stretches. Wi-Fi is required for the free lifetime updates, and the screen is a 5-inch touchscreen with physical buttons. Printing diagnostic reports goes through email, so you will need a connected phone or computer for that step.
Who should choose this and who should skip it
Choose the AD500 if you want four-system coverage, six reset functions, and a scanner that can handle modern CAN FD vehicles without a trip to the dealer for every code. It suits a DIYer who wants to see engine, transmission, ABS, and SRS data and clear those codes at home.
Skip it if you need a tool that goes beyond those four systems, or if your car's coverage is not listed. Also skip if you want a repair device rather than a diagnostic one. Check your model's coverage first, then decide whether the current price fits your budget.
