What types of data can I retrieve with an OBD scanner?

An OBD scanner, which stands for On-Board Diagnostics scanner, is a tool that interfaces with a vehicle's onboard computer system to extract a variety of data related to the vehicle's performance and health. Typically, users can retrieve several key types of data with these scanners, including diagnostic trouble codes, also known as DTCs. These codes indicate specific issues with the vehicle, ranging from minor concerns to serious malfunctions. In addition to DTCs, an OBD scanner can provide real-time data about various engine parameters. This includes information such as engine RPM, vehicle speed, coolant temperature, fuel trim levels, and oxygen sensor readings. Such real-time data can offer valuable insights into how the vehicle is operating at any given moment. Another important type of data that can be accessed is the freeze frame data, which records specific parameters at the time a fault was detected. This may include data points like engine load, engine coolant temperature, and vehicle speed, which can help in diagnosing problems effectively. Moreover, certain advanced OBD scanners may also enable users to view additional information such as readiness monitors, which indicate whether certain emissions-related systems are functioning correctly, and even live data from advanced driver assistance systems, depending on the vehicle's capabilities. Overall, OBD scanners are versatile tools that are indispensable for both professional mechanics and car enthusiasts, allowing them to monitor vehicle health and diagnose issues efficiently.
