What is OBD2? What are OBD2 PIDs? And how to log OBD2 data?

In this basic intro to OBD2 we go through the basics, data logging, PIDs and more!

OBD (On Board Diagnostics) is the vehicle's self-diagnostic system. It allows for a standardized method for accessing various data, diagnostic trouble codes and more from cars, medium-duty and heavy-duty vehicles. In practice, the OBD2 protocol allows a mechanic to use e.g. an OBD2 scanner or code reader to identify the underlying issues behind a lit malfunction indicator light (MIL). But OBD2 is also relevant as a source of real-time vehicle data for use in e.g. fleet management, fuel optimization, CAN sniffing and more.

In this video and the article, we in particular focus on the data logging part of OBD2 - how is a message structured, what is an OBD query / request vs. a response message, what are OBD2 PIDs and much more. We do so through concrete examples like Vehicle Speed and RPM to make it easy to understand.
