On-board diagnostics (OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with federal emissions standards to detect failures that may increase the vehicle tailpipe emissions to more than 150% of the standard to which it was originally certified.

On-Board Diagnostics (OBD) is the built-in system in modern vehicles that monitors engine health, emissions performance, and overall drivability. If you’re trying to understand a Check Engine Light or diagnose a rough idle, OBD is how your car “tells you” what it sees—through codes and live data.
OBD, or on board diagnostics, was introduced by General Motors in 1981 to monitor the emission control system in the car. In 1986 California mandated that all cars sold in the state be equipped with OBD, and it became the industry standard.

That's where Onboard Diagnostics (OBD2) comes in. OBD2 is a system that allows your car to communicate with you about potential faults. In this guide, we'll break down how OBD2 works, why it's essential, and how you can use it to keep your vehicle healthy. Let's dive in!
OBD stands for On-Board Diagnostics and is a computer system inside of a vehicle that tracks and regulates a car’s performance. This on-board computer system collects information from the network of sensors inside the vehicle, which the system can then use to regulate car systems or alert the user to problems.
