What is an OBD scanner?

An OBD scanner, or On-Board Diagnostics scanner, is a device that communicates with a vehicle's onboard computer system to retrieve important information about its performance and health. This tool is essential for diagnosing potential issues within the vehicle, as it can read trouble codes generated by the engine and other systems. When a problem occurs, the onboard computer stores a trouble code that indicates where the issue may lie, allowing mechanics and vehicle owners to troubleshoot more effectively. Most modern vehicles are equipped with an OBD-II system, which standardizes the information obtained from the vehicle's computer. An OBD scanner can display real-time data, including engine performance metrics, fuel efficiency, and emissions information. Some advanced scanners also offer additional functionalities, such as live data streaming and vehicle health reports. These devices can be invaluable for vehicle maintenance, helping to identify issues early and save on costly repairs.
