Understanding Top Don Scanners
Top-don scanners, also known as OBD2 scanners, are handheld electronic devices that connect to your car’s On-Board Diagnostics (OBD) system through a standardized port usually located under the dashboard. This system acts as your car’s internal communication network, constantly monitoring various sensors and components for optimal performance.
When an issue arises, the OBD system generates a specific code that is stored in its memory. Top-don scanners retrieve these codes, providing valuable insights into the nature of the problem. They translate these cryptic codes into understandable descriptions, such as “Engine Misfire Cylinder 2,” enabling you to pinpoint the root cause of the issue.
