Using an OBD2 scanner is a relatively simple process that can provide crucial information about the vehicle’s electronic and mechanical components alike.

Discover what an OBD2 scanner is and how to use it to diagnose and fix car problems before they escalate into major repairs.

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.

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.

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.

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