Understanding the OBD2 System in Your 2006 GMC Sierra

The OBD2 (On-Board Diagnostics II) system is your vehicle’s self-diagnostic system. It constantly monitors various systems and components, alerting you to potential problems via the dashboard warning lights and storing diagnostic trouble codes (DTCs). These codes can be retrieved using an OBD2 scanner, allowing you to pinpoint the source of the issue. The OBD2 port, often located under the dashboard on the driver’s side, is the gateway to accessing this valuable information.
