Advanced OBD2 scanners with simple-to-navigate menus and that explain features score well in this category. Live data graphing : OBD2 scanners may be capable of monitoring any number of car systems. A live graphic function displays this data (such as engine temperature) as a graph in real-time. This function can help diagnose certain engine issues or be used to optimize performance. This feature is not something that the layperson is likely to find useful, however. For non-mechanics, the most useful OBD2 scanner features are reading error codes and the smog test. More advanced features are only useful when paired with at least some mechanic know-how. OBD2 Features: What Experts Are Saying Freeze frame data : Some OBD2 scanners can record freeze frame data. This is information about your vehicle’s systems at the time when an error code occurred. Freeze frame data is useful for diagnosing problems.

All of the OBD2 scanners that we recommend are compatible with a broad range of vehicles. However, not every OBD2 scanner works perfectly with every vehicle.
