CHOYOE • Multi-Language Color Screen OBD2 Scanner & Auto Repair Tool V529
The CHOYOE V529 is a professional OBD2 engine diagnostics tool designed for car owners, mechanics, and DIY enthusiasts. The instrument features a vibrant 2.8-inch color screen and supports nine standard OBD-II/EOBD protocols, working reliably with gasoline and diesel vehicles from 1996 (USA), 2003 (EU), and newer. Key built-in functions include reading and clearing engine fault codes (DTCs), viewing real-time data such as RPM, coolant temperature, and battery voltage, as well as I/M readiness and VIN auto-identification. The tool supports ten languages for global usability, and no external power source or app is needed — power comes through the vehicle’s OBD2 port.
