If you've ever had your check engine light come on and wondered what was wrong, you’ve already brushed up against the concept of car scanning. But what exactly is car scanning, and how can you do it without a trip to the repair shop?

Car scanning, also known as vehicle diagnostics, is the process of using an OBD2 (On-Board Diagnostics) scanner to communicate with your car’s computer system. This system tracks everything from engine performance to emissions, transmission, battery voltage, sensor behavior, and more. When something goes wrong, the system stores a Diagnostic Trouble Code (DTC), which can be read using a scanner.

A typical scan will check for current, pending, or historical codes related to your vehicle’s systems. These codes help identify problems like misfires, oxygen sensor failures, EVAP leaks, transmission issues, or even something as simple as a loose gas cap. In short, car scanning tells you what your car “knows” but can’t say directly.

So where does the VDIAGTOOL VD80BT come in?

The VD80BT is a professional-grade OBD2 scanner designed for both beginners and experienced users. Unlike many basic code readers, the VD80BT offers a wide range of advanced features while remaining user-friendly and portable.
