Libre Diagnostic
Open hardware car diagnostics
Car diagnostic has evolved from the early OBD-I systems of the 1980s to today’s OBD-II standard. While some commercial scanners provide real-time vehicle data and trouble code readings, they are proprietary, limiting transparency and customisation. An open-source alternative will offer greater control, community-driven improvements, and long-term affordability.
This project aims to develop a cost-effective and user-friendly diagnostic tool that connects to a vehicle’s OBD-II system via Bluetooth using the ELM327 adapter. It will allow users to read and clear diagnostic trouble codes (DTCs), monitor real-time performance data, and analyse key systems like ABS, airbags, and engine health. The project will provide a transparent, accessible, and reliable diagnostic solution for both car owners and professionals.
