The interface supports OBD2-compliant vehicles and is intended for routine troubleshooting, maintenance checks, and emissions-related diagnostics where OBD2 access is available.

Usage recommendations
Use official or well-reviewed third-party OBD2 apps compatible with ELM327-based adapters to ensure correct interpretation of data.
