I'm a developer and electronics enthusiast from Spain, currently working on a custom diagnostic interface. I’ve built a hardware setup based on an ESP32-S3, using an SN65HVD230 for CAN-bus and an MC33290 for K-Line, powered by an LM2596 regulator.
Project status: I have developed a web-based dashboard that communicates with the ESP32 via WebSockets to read real-time DTCs. My current goal is to move beyond generic OBD2 and implement:
I’m here to dive deeper into ISO-TP implementation and security access (Seed/Key) for these modules. I'm happy to share my ESP32 firmware logic and hardware schematics with anyone interested in DIY open-source tools.
Looking forward to learning from the experts here!

- VAG Group (UDS/KWP2000): Specifically for Airbag resets and EPB service mode on older platforms like the Seat Alhambra.
- Renault (CAN-bus): Service interval resets and specialized coding using DDT4all-style commands.
