I took a fork of pyOBD’s software from their GitHub repository,, and used this as the basis for my program. It will basically allow you to talk to your car's ECU, display fault codes, display measured values, read status tests, etc. It is designed to interface with low-cost ELM 32x OBD-II diagnostic interfaces such as ELM-USB. PyOBD (aka pyOBD-II or pyOBD2) is an open source OBD-II (SAE-J1979) compliant scantool software written entirely in Python. It has positions for 16 pins, and looks like this:
The OBD connector is officially called a SAE J1962 Diagnostic Connector, but is also known by DLC, OBD Port, or OBD connector. Vehicles that comply with the OBD-II standards will have a data connector within about 2 feet of the steering wheel. Now you can think of OBD-II as an on-board computer system that is responsible for monitoring your vehicle’s engine, transmission, and emissions control components. OBD stands for On-Board Diagnostics, and this standard connector has been mandated in the US since 1996.
