TOPDON AD600 OBD2 Scanner: features, reset functions and who it suits

The TOPDON AD600 is a handheld diagnostic scanner for cars. It connects to the OBD2 port, reads and clears fault codes from several systems and can run a set of maintenance resets. It is an upgraded version of the AD600, with more storage and Android 11.

Four systems, not just the engine

A basic reader only checks the engine. TOPDON says the AD600 also covers the transmission, ABS and SRS (airbag) systems, each a separate control unit in the vehicle. It reads and clears codes and shows live data streams. A DTC lookup function gives a description of each fault code, which helps in understanding what the car is reporting. AutoVIN reads the vehicle identification number automatically to speed up setup, and reports can be sent to TOPDON's support team.

The eight reset functions

After some jobs the car's computer must be told that the work has been done. TOPDON lists eight: oil, BMS, ABS, SAS, EPB, DPF, TPMS and throttle.

• Oil and throttle: clearing the service reminder and relearning throttle position.
• BMS: battery management reset, relevant on cars that monitor battery charge.
• SAS: steering angle sensor calibration, often required after alignment work.
• EPB: electronic parking brake service for pad changes on some vehicles.
• DPF: diesel particulate filter regeneration functions on supported diesels.
• TPMS and ABS: tyre-pressure and brake-system service functions.

Support differs per vehicle, so check coverage for your car. The listing also mentions injector coding and ETS reset in its title.

Display, storage and updates

The 5-inch screen has a resolution of 1280 x 720, and the tool runs Android 11 with 32 GB of storage. Updates arrive over Wi-Fi in one click, and TOPDON describes them as lifetime updates that add vehicle coverage over time. The unit weighs about 2.2 lb (1 kg).

Coverage

TOPDON says it supports 67+ global brands and 10,000+ models, including American, German, French and Japanese makes. The listing advises contacting TOPDON about compatibility before buying, which is sensible for older, rarer or specialised vehicles.

Who it suits

It suits home mechanics who do their own servicing, owners who want to understand a warning light before visiting a garage, and families with a mix of cars. Diesel owners may value the DPF function, provided their vehicle is supported.

What to check before you buy

• Your vehicle: confirm make, model, year and the specific systems and resets you want.
• Diagnostic port: make sure the car has a standard OBD2 connector.
• Internet: updates need Wi-Fi.
• Interpretation: a code points to an area to inspect. It does not always name the failed part.
• Safe procedures: follow the vehicle's service manual and local rules, especially for brakes and airbags.
