OBD2 Scanner TOPDON AD600S Scan Tool - 9 Reset Services & 4-System

Our review of the TOPDON AD600S finds it best suited for home mechanics, DIYers, and small-shop technicians who need broad OBD2 coverage and practical reset functions without a subscription. The AD600S stands out because it combines full OBDII diagnostics with nine reset services including the newly added Injector Coding, and offers one-click lifetime updates over Wi-Fi, making it a convenient all-in-one code reader and service tool for routine maintenance and troubleshooting.

Key Features

• 9 Reset Services: Includes OIL RESET, BRAKE RESET, TPMS RESET, Throttle Adaptation, SAS RESET, BMS RESET, ABS BLEEDING, DPF RESET and Injector Coding for a wide range of maintenance tasks.
• 4-System Diagnostics: Access AT, ENG, ABS and SRS fault codes to isolate module-level problems and find the right repair direction.
• Full OBD2 Test Modes: Supports 10 OBD2 test modes to diagnose emission issues and read live data for troubleshooting.
• Auto VIN and DTC Library: Automatic VIN identification and an onboard DTC library speed up vehicle ID and code interpretation without manual lookup.
• One-Click Lifetime Updates: Wi-Fi updates keep the scanner current with free lifetime software upgrades and a 32G internal memory for reports.
• Touchscreen and Reports: A responsive touch screen with a 5-color display and live graphing allows saving, sharing, or printing inspection reports.

Who It's For

The AD600S is ideal for DIY enthusiasts, hobby mechanics, and independent technicians who want more than a basic code reader but do not need dealership-level programming. Its mix of OBD2 functionality, nine service resets and Injector Coding covers common service tasks and routine maintenance on many late-model vehicles.

Those who depend on manufacturer-level programming, work on heavy-duty 24V diesel commercial vehicles, or require guaranteed FCA gateway authorization for every model should verify vehicle compatibility before purchase; menu availability varies by make, model and year.
