What does OBD on a car mean?

The meaning of OBD on a car is: 1. To display various vehicle data that cannot be shown on the dashboard through the car's OBD diagnostic system. Many pieces of information that the original dashboard cannot display can be read via OBD, and with a display unit, various vehicle data such as fuel consumption, instantaneous fuel consumption, interior temperature, water temperature, and battery voltage can be displayed. 2. Many features not originally included or disabled in the vehicle can be enabled through the OBD module, such as unlocking hidden functions. There are specialized cables and software available for this purpose. OBD stands for 'On-Board Diagnostic' system. This system is primarily used to monitor the engine's operating status and the working condition of the exhaust treatment system in real-time. 3. If the system detects abnormal data, it indicates that the system is not functioning properly. The OBD will store the fault code and illuminate the malfunction indicator lamp. Repair personnel can then read the fault code using diagnostic tools to analyze the cause of the malfunction.
I understand that automotive OBD stands for On-Board Diagnostics, known in Chinese as the onboard diagnostic system, which acts like a health monitor for cars. Since the 1990s, the United States has mandated the OBD-II standard, and now most vehicles are equipped with this system, using sensors to monitor engine, emissions, and other components in real time. If issues arise, such as engine abnormalities or excessive emissions, it stores fault codes and illuminates the warning light on the dashboard to alert you. During repairs, plugging in a scan tool can read these codes to quickly pinpoint the problem area, saving money and improving efficiency. This also benefits the environment by helping reduce exhaust pollution. I recommend regularly using an OBD scanner for check-ups to prevent minor issues from turning into major repairs.
