Have you ever been stuck on the side of the road, with a car that won’t start? It’s a stressful situation, and you’re probably wondering what’s wrong. It’s a good thing there’s a solution that can help: a scan tool! These devices can read the codes from your car’s computer, helping you diagnose the problem and get back on the road. If you’re thinking about buying a scan tool for your car, you’re likely wondering where to start. AutoZone is a great place to find scan tools for cars. But with so many different options available, how do you know which one is right for you?
What is a Scan Tool?
A scan tool is a device that plugs into your car’s OBD-II port, which is a standardized connector located under your dashboard. It allows you to communicate with your car’s onboard computer, read diagnostic trouble codes (DTCs), and even reset warning lights. These DTCs are like error messages, giving you insight into what’s going wrong with your car. Some scan tools can even perform more advanced functions, such as graphing live sensor data and clearing DTCs.
Why Use a Scan Tool?
Imagine you’re driving your car and suddenly the check engine light comes on. What do you do? Do you take it to a mechanic? Do you ignore it and hope it goes away? A scan tool can be your best friend in these situations. It can help you identify the cause of the problem, which can save you money in the long run.
Many scan tools are designed for home mechanics, making it easier to diagnose problems and save money by doing your own repairs. You can even use a scan tool to perform routine maintenance checks, like monitoring your vehicle’s emissions system.

- Compatibility: Make sure the scan tool you choose is compatible with your car’s make, model, and year. Not all scan tools work with every vehicle.

- Clear the DTCs. Some scan tools allow you to clear the DTCs after you’ve addressed the problem.
Troubleshooting with a Scan Tool
Scan tools are great for diagnosing a wide range of issues. Here are a few examples:
- Check Engine Light: The check engine light can come on for a variety of reasons, from a loose gas cap to a more serious engine problem.
- Transmission Problems: You can use a scan tool to diagnose transmission problems, such as rough shifting, slipping, or complete failure.
