Modern cars are more than oil, steel and wheels; they have more than 50 modules that control electronic functions, which is why maintaining them requires a little more skill than simply changing a tire or adjusting the brakes. An obd 2 scanner (or OBD-II scan tool) is an essential diagnostic device that can help owners and DIY mechanics track issues, find solutions and clear check engine lights.

A good OBD2 scanner will read engine codes and may have other features that can help you troubleshoot a problem, such as freeze frame data or displaying live car system data on a graph in real time. While these are nice to have, they are not necessary for most people who will use a scanner for the basic function of pulling codes.

Harnessing Automotive Intelligence: Exploring the Benefits of OBD2 Scanners

There are two types of OBD2 scanners: a dedicated hand-held device that plugs directly into the vehicle’s OBD port, and wireless models that pair with a smartphone via Bluetooth. The hand-held scanners have their own screen, buttons and software and are easy to use, although they tend to be more expensive than the wireless versions.

Many of the more advanced consumer-priced OBD2 scanners today do things that were reserved for $5,000 pro-grade scanners just a few years ago, so they’re a good choice for someone who feels comfortable working on their own car. However, it’s important to note that some scanner features or commands don’t work on every make and model of car, which is a result of how the automakers set up their control architecture or operating software.
