An OBD2 (On-Board Diagnostics II) scanner can provide information about the status and health of various vehicular systems.

The Seekone OBD2 Code Scanner – SK860 can collect, read and erase codes quickly and easily. It focuses on ECU data which triggers the check engine light in vehicles because of several issues.

Reading and understanding OBD2 trouble codes today couldn't be easier. This is partly because of tools like Innova's Digital CAN OBD2 Code Reader.

We recently got our hands on the new GoTech mobile OBD-II diagnostic tool and put it through its paces on several trucks in our fleet. The GoTech is more than just a code reader, though.

The scanner you buy should depend on which cars you plan to use it on most often. Some code readers are designed to work best with certain brands or even certain cars.

The BlueDriver OBD2 scan tool is on sale at Amazon for $80, and shoppers say it’s an ‘easy plug-and-play’ solution.

Already an affordable option, right now you can save over $25 on this diagnostic code reader from trusted brand Ancel.
