Developed in the 1980s to help control vehicle emissions, on-board diagnostics (OBD) is a computer system that monitors the performance of some engine components. The system, —which includes sensors, actuators, and an electronic control unit—senses problems, collects data, and activates alerts, such as the “check engine light.”
In the early years, on-board diagnostics only detected issues and illuminated the “check engine light.” Today, OBDII technology is much more sophisticated, providing real-time data and diagnostic trouble codes that allow technicians to quickly determine the cause of malfunctions.
