Scan Tools and Code Readers The two main categories of high-tech car diagnostic tools are code readers and scan tools. The most basic computer diagnostic tools are simple code readers, which means they can pull codes from your car’s computer. You can then look that code up, which provides you with a starting point for your diagnostic procedure. In most cases, a code reader will allow you to read and clear codes. The ability to clear the codes is important since that allows you to see if your repair fixed the problem or not. Some code readers also provide basic access to live or freeze frame data from the computer. Scan tools are code readers that have some added functionality. Basic scan tools allow you to read and clear codes, but you can also view all of the available data from the car’s computer. Depending on the tool, you may be able to scroll through all of the available information or set up your own list of parameter IDs (PIDs) that you are interested in. In addition to reading codes and displaying PIDs, scan tools typically also provide a little more information about the codes. Depending on the specific scan tool, it may simply display some very basic information about what each code means, or it might provide some level of information about how to proceed with your diagnostic. The most expensive scan tools provide extensive knowledge bases that can speed up a diagnostic procedure considerably.
