OBD II Overview
OBD II is a generation of on-board diagnostics developed to monitor emission control systems and key engine components. It provides a warning lamp on the dashboard to alert the driver of any issues and stores information about the detected malfunction.
DTCs (Diagnostic Trouble Codes)
DTCs are five-digit alphanumeric codes that identify specific problems in the vehicle. They provide a guide for where a fault might be occurring within the vehicle.
Location of the Data Link Connector (DLC)
The DLC is a standardized connector where diagnostic scan tools interface with the vehicle’s on-board computer. It is usually located under the dashboard, but may be found in other locations depending on the vehicle make and model.
