Description

What is OBD-II?

OBD-II (short for On-Board Diagnostics, Second Generation) is a set of standards for implementing a computer-based system to control emissions from vehicles. Also, it can be explained as a vehicle’s built-in self-diagnostic system. When your vehicle has an internal issue, it would normally pop up a malfunction indicator light on your dashboard, telling you to visit a mechanic and get the issue fixed. In the past, this light would just indicate, but it was not possible to identify what the issue was. But nowadays, the OBD-II built inside vehicles, allows you to identify the exact problem of the vehicle by connecting an OBD-II reader to the OBD-II 16-pin connector built inside the vehicle. Through this, it's possible to read OBD-II codes which are also known as Diagnostic Trouble Codes (DTCs) which are helpful in understanding the issues, without needing to completely disassemble the vehicle.

OBD-II was first introduced in the United States in 1994 and became a requirement for all 1996 and newer US vehicles. Other countries, including Canada, parts of the European Union, Japan, Australia, and Brazil adopted similar legislation. A large portion of the modern vehicle fleet supports OBD-II or one of its regional flavors.

What are OBD-II PIDs?

OBD-II PIDs(Parameter IDs) are a set of codes that are used to request data from a vehicle. Through OBD-II PIDs, you can obtain vehicle data such as speed, throttle position, and RPM of the engines.
