OBD-II (On-Board Diagnostics II)

OBD-II (On-Board Diagnostics II) is a standardized system in vehicles that monitors the engine and other important components for issues. It collects data from various sensors and systems, and if a problem occurs, it stores diagnostic trouble codes (DTCs). These codes can be read using a scanner or code reader, helping mechanics and car owners identify and fix problems efficiently. OBD-II promotes quicker diagnosis, reduces repair costs, and helps maintain vehicle performance and emissions by continuously monitoring the vehicle’s health. It’s a universal system found in almost all cars manufactured since 1996.
