A diagnostic tool is a device or program that performs automatic examinations of your computer hardware and system configuration. These tools are especially helpful when you encounter a problem that your normal software programs cannot resolve on their own. Computer diagnostic tools are important because they allow you to discover hard-to-find problems that would otherwise be difficult or impossible to find without the aid of a sophisticated tool such as a specialized scanner.

If you are a car owner, you know the value of a good diagnostic tool. In fact, the use of a diagnostic tool can help you solve many problems on your own or save money by bypassing the cost of a professional mechanic. The basic diagnostic tool is a code reader, which reads the trouble codes that are stored in your vehicle’s onboard computer and helps you make sense of them. You can also purchase a more sophisticated diagnostic tool that will do things like clear the codes, monitor real-time data, and even provide freeze-frame information that gives you a snapshot of the vehicle’s status when the code was triggered.

These diagnostic tools are available to anyone with a post-1996 vehicle. Plug in the diagnostic tool, apply power to it, and it will begin running electronic tests and looking for any trouble codes that are triggered. Higher-end diagnostic tools will display the code descriptions right on the screen. From here, you can either fix the problem yourself or take your vehicle to a mechanic. Ultimately, the choice will depend on your level of mechanical skill and experience.
