Topscan Pro (Mobile Phone DIY Diag)

The TOPDON TopScan Pro is a compact Bluetooth OBDII diagnostic tool that transforms your smartphone into a powerful vehicle diagnostic scanner. Designed for both professional technicians and experienced DIY enthusiasts, it offers far more than basic code reading, providing advanced diagnostics, maintenance functions, and intelligent troubleshooting in a pocket-sized device.

Simply connect the TopScan Pro to the vehicle's OBDII port, pair it with the dedicated TOPDON app, and gain access to professional diagnostic functions directly from your smartphone or tablet. Supporting more than 70 vehicle manufacturers across European, Asian, and American markets, it provides broad compatibility for a wide range of petrol and diesel vehicles.

The TopScan Pro performs full-system diagnostics, allowing users to communicate with all major electronic control modules, including the Engine, Transmission, ABS, Airbag (SRS), Body Control, and many other vehicle systems. It enables technicians to read and clear fault codes, monitor live data, retrieve freeze-frame information, and quickly identify vehicle faults with confidence.

To support routine servicing, the TopScan Pro includes 13 commonly used maintenance service functions, helping users perform essential procedures such as:

• Oil Service Reset
• Electronic Parking Brake (EPB) Reset

• Diesel Particulate Filter (DPF) Regeneration
• Throttle Adaptation
• Injector Coding
• And other vehicle-dependent service functions.

The scanner also features Bi-Directional Control (Active Tests), allowing technicians to activate individual vehicle components and verify their operation without removing parts. This makes it easier to diagnose faults involving cooling fans, fuel pumps, injectors, windows, relays, and other electronically controlled systems.

With AutoVIN technology, the TopScan Pro automatically identifies compatible vehicles, reducing setup time and allowing users to begin diagnostics more quickly.

To further assist with repairs, the scanner includes a comprehensive Repair Knowledge Base and a full-system DTC Repair Guide, providing valuable fault code explanations and repair information to help technicians diagnose issues more efficiently. A convenient One-Click I/M Readiness function also allows users to quickly check emissions readiness before an MOT or emissions inspection.

The TopScan Pro also offers Vehicle Performance Testing, enabling users to measure acceleration and other key performance metrics directly from their smartphone, making it useful for performance analysis and post-repair verification.

Supplied with 12 months of software updates from new, the TOPDON TopScan Pro combines portability, professional diagnostic capabilities, intelligent repair guidance, and essential maintenance functions into one affordable solution. Whether you're maintaining your own vehicle or working in a professional workshop, the TopScan Pro provides the tools needed to diagnose, service, and repair modern vehicles with confidence.
