Understanding OBD-II and Diagnostic Trouble Codes (DTCs)
On-Board Diagnostics II (OBD-II) is a standardized system that allows access to a vehicle’s diagnostic information. It’s the backbone of car diagnostic scanner apps, providing a common language for retrieving and interpreting data. When a problem is detected, the OBD-II system generates a Diagnostic Trouble Code (DTC), a unique alphanumeric code that identifies the specific fault.
Understanding DTCs is essential for diagnosing car problems. Car diagnostic scanner apps translate these codes into plain English, providing a clear understanding of the issue. However, it’s crucial to remember that DTCs are just starting points. Further investigation is often required to pinpoint the exact cause and implement the necessary repairs.
