An OBD II code reader is a great tool to have. It’s an electronic device that allows you to plug into your computer’s OBD diagnostic port and access technical information such as check engine codes for your car.

Up until the last few years, owning your own OBD II code reader tool was uncommon. But now you often find them in the do-it-yourselfer’s tool box. That’s because these code scanners are incredibly useful for diagnosing and fixing 1996 and newer vehicles.

The typical OBD II code reader is a handheld unit that allows you to view any stored diagnostic trouble codes (DTC’s) to help troubleshoot problems with cars and trucks. Some basic features may include:

- Viewing diagnostic trouble codes for your vehicle
- Ability to reset or clear DTC codes
- LCD screen readouts
- Code definitions right on the unit

The OBD-II code reader is so handy to have. It’s fun to pull codes and find out for yourself what’s going on with your vehicle. It can save you a lot of money too. Everyone should have there own OBD II code scanner!
