Quick fault isolation - with bi-directional control
Bi-directional control sends commands from the smartphone app to the vehicle ECU for active tests, exercising components such as A/C clutch, windows, doors and sunroof to reproduce or verify faults. The app completes pairing via Bluetooth 5.0 and runs tests through the TopScan or TOPGURU applications.
Active testing helps narrow down fault sources faster, reducing diagnostic time for workshops and making it easier for DIYers to locate faults without guesswork.
Practical repair capability - thanks to 8+ reset functions
Eight or more reset procedures are available, including Oil Reset, Throttle Adaptation, EPB Reset, Steering Angle Reset, DPF Regeneration, ABS Bleeding, BMS Reset and Airbag Reset, all accessed through the app-led menus.
Routine maintenance and many post-repair procedures can be completed at home or in a small garage, cutting unnecessary workshop visits and saving time on common repairs.
Broad vehicle support and easy updates - with app-based Bluetooth and online upgrades
Support covers thousands of vehicle models, compatible with most OBDI and OBDII cars after 1996, and includes a vehicle compatibility lookup in the app. One-click online upgrades deliver the latest software, with one year of free updates included.
