Top 10 Scan Tools
for October 2022

A scan tool is an electronic diagnostic tool that plugs into a vehicle's diagnostic port and connects to a vehicle's computer, allowing the user to view the vehicle's computer's diagnostic trouble codes (DTC). These codes tell the user what the problem is.

While a scan tool isn't required to diagnose a DTC, it is an excellent way to diagnose a DTC, especially when the DTC is accompanied by a symptom. A scan tool can also tell you which parts need to be replaced.

Our scan tool experts have tested hundreds of scan tools over the years, testing them on a variety of vehicles, from cars to SUVs to trucks. We tested the scan tools' ease of use, including how easy it is to set up the tool, how intuitive it is to use, and how clear the instructions are. We also evaluated the scan tools' diagnostic capabilities, including how quickly they scan the vehicle's computer, how well they diagnose problems, and how many problems they diagnose. These are the best scan tools you can buy right now:
