2026 TOPDON Topscan All System Diagnostic Scanner OBD Tool Oil Reset Code Reader

The TopScan Lite expands with more new features and turns your smartphone into a smart diagnostic tool, so you can better understand and maintain your beloved vehicle — while getting the detailed information you need to avoid automotive repair scams.

Works with both iPhone and Android. Powered straight from your vehicle. Just pair and go.

This bi-directional scan tool lets you send commands from your smartphone directly to the vehicle’s ECU for active testing. Quickly narrow down problem areas such as the A/C clutch, windows, doors, and sunroof.

It reduces a mechanic’s diagnostic time and helps DIY users pinpoint faults more easily — plus it delivers fault analysis and repair guidance so you can solve problems efficiently.

TopScan Lite supports OBD2 full-system diagnosis functions, including:

• Read & clear codes
• ECU information
• AUTO VIN identification
• View real-time live data
• Active tests

Understand your car inside and out, and skip the guesswork at the shop.

Save on unnecessary repair costs and cut repair time with 8+ popular reset functions:

• Oil Reset
• Throttle Adaptation
• EPB Reset
• Steering Angle Reset
• DPF Regeneration
• ABS Bleeding
• BMS Reset
• SRS Reset

TopScan Lite lets you access the FCA gateway to perform protected functions on FCA vehicles — Chrysler, Dodge, Jeep, Fiat and more.

It also supports speed performance testing, so you can analyze speed changes and calculate engine displacement efficiency. The higher the VE (volumetric efficiency), the better the engine’s power output performance.

Four practical functions every car owner, DIY enthusiast, and mechanic will love:

• TSB factory technical bulletins with easier, more convenient search
• OBD common fault-code repair guidance to solve problems fast
• DLC diagnostic-seat location for quick positioning
• Fault-code database explaining reasons & solutions for every warning light
