Compatibility notes
- This build matches the legacy X-431 PC ecosystem. It is commonly associated with older X-431 family devices (for example X-431, TOOL, GX3 and Diagun generations).
- You need a compatible LAUNCH communication interface. USB driver availability varies by interface version.
- Functions and system coverage depend on vehicle model year, ECU firmware, and the specific module folder. Availability varies by vehicle and firmware.
- Modern Android tablet-based X-431 products use different apps and update workflows and are not compatible with this legacy PC layout.
Basic usage
- Extract the folder to a short path (example C:\X431\)
- Install required USB drivers if your interface uses an FTDI-based connection
- Run DiagunShow.exe as Administrator
- Select the vehicle brand module, then connect the interface and start diagnosis
- Save logs or reports to the Save or Running_Record folders as needed
Operating systems
- Windows 7 (x86/x64)
- Windows 8 / 8.1 (x86/x64)
- Windows 10 (x86/x64)
- Windows 11 (x64, may require compatibility mode for older components)
Minimum system requirements
- CPU: Dual-core 2.0 GHz or better
- RAM: 4 GB minimum (8 GB recommended)
- Storage: 1 GB free for program files plus extra space for logs
- Network: Not required for offline work (optional for official updates and documentation)
- Permissions: Local Administrator rights for driver install and first run
