In addition to interfacing with the on board diagnostic system of a vehicle, the other most important thing a scan tool can do is to provide you with some type of knowledge base. The specific information contained in this type of knowledge base varies from one scan tool manufacturer to another, but it’s almost impossible to overstate the importance of good troubleshooting information.

Unless you have relevant prior experience with the specific problem that you’re dealing with, a good knowledge base can save you a tremendous amount of time. Scanners that include troubleshooting information and other tips will typically provide you with the definition of a code, the potential faults that can lead to that code being set, and the tests that you can do to track down the root cause of the problem.
