Product description
This wireless OBD2 scanner from TOPDON lets you run full vehicle diagnostics from a smartphone, combining an all-system scan with active tests and reset functions to speed up troubleshooting and basic maintenance. It is useful for DIYers and workshop technicians who want real-time data and the convenience of Bluetooth connectivity for iOS and Android devices. The tool aims to reduce diagnostic time by allowing direct commands to the vehicle ECU and providing repair guidance.
Key Points

TopScan supports bidirectional control that sends commands from your phone to the ECU so you can perform active tests and isolate faults quickly. This helps locate issues with components such as the air conditioning clutch, windows and sunroof, making fault finding more focused and efficient. 🔧


The scanner includes more than eight maintenance resets, covering oil reset, throttle adaptation, EPB reset, steering angle reset, DPF regeneration, ABS purge, BMS reset and airbag reset. These functions can reduce avoidable workshop labour when used correctly, according to the manufacturer. ⚙️

TopScan offers online repair resources including factory technical service bulletins, a searchable database of fault code causes and fixes, DLC diagnostic socket location guides and common-code repair guides. These features are designed to streamline repairs and provide step‑by‑step support during diagnosis. 📘
Note that TopScan provides one year of free software service. After the free period, subscription options are available and some advanced features may require a subscription, according to the manufacturer. Consider this when planning longer term use.

Usage Recommendations


For mobile use, install the TopScan app on your iPhone or Android device and pair via Bluetooth before connecting to the vehicle. Perform a vehicle VIN auto-detect to ensure the app loads the correct ECU information, and use live data streams to verify sensor readings while running active tests. When carrying out resets such as DPF regeneration or EPB procedures follow the vehicle manufacturer’s service instructions and observe safety precautions.

Access to FCA gateway functions is supported but requires your own FCA account for protected operations. Use the performance test feature to record speed changes and calculate volumetric efficiency VE when assessing engine breathing and power delivery. This can be helpful when tuning or after repairs to compare before and after data.
Benefits

By providing active testing, live data and repair guidance in one compact interface, TopScan can shorten diagnostic loops and help users make informed repair decisions. The combination of mobile convenience and a broad function set allows home mechanics to tackle a wider range of tasks while giving professionals a rapid screening tool. There may be limitations for very specific manufacturer proprietary functions, and some advanced capabilities will depend on subscription level and vehicle permissions.
