Best Selling Code Readers & Scan Tools

A code reader, also known as an OBD2 scanner, is a device that can be used to diagnose problems with a vehicle's engine. It can read and clear diagnostic trouble codes (DTCs), which are stored in the vehicle's computer. DTCs can indicate a wide range of problems, from a simple misfire to a more serious issue such as a faulty engine sensor.

Scan tools are more advanced than code readers and can perform a wider range of diagnostic tests. They can also read live data from the vehicle's computer, which can be helpful in diagnosing problems. Scan tools are often used by professional mechanics, but they can also be purchased by DIYers.

How to Use a Code Reader or Scan Tool

Using a code reader or scan tool is relatively simple. First, connect the device to the vehicle's OBD2 port. This is usually located under the dashboard. Once the device is connected, it will automatically scan the vehicle's computer for DTCs. The DTCs will be displayed on the device's screen.

If there are any DTCs, you can look up their meaning in the device's manual or online. The DTCs will usually indicate the general area of the problem, such as the fuel system or the ignition system. Once you know the general area of the problem, you can start troubleshooting.

If you are not comfortable troubleshooting a vehicle, it is best to take it to a professional mechanic. A mechanic can use a scan tool to diagnose the problem and make the necessary repairs.
