1.1 What is On-Board Diagnostics (OBD)?

What is OBD, and how does it work?OBD, or On-Board Diagnostics, is a standardized system that monitors a vehicle’s performance. It uses sensors to detect malfunctions in the engine, transmission, exhaust system, and other components. According to the Environmental Protection Agency (EPA), OBD systems have been mandatory on all cars sold in the US since 1996. When a problem is detected, the OBD system stores a diagnostic trouble code (DTC) and may illuminate the “check engine” light on the dashboard. Mechanics and car owners can use scan tools to retrieve these codes and diagnose the issue.

1.2 What are Diagnostic Trouble Codes (DTCs)?

What are DTCs, and how are they interpreted?Diagnostic Trouble Codes (DTCs) are codes stored by the vehicle’s OBD system when a malfunction is detected. These codes provide information about the nature and location of the problem. According to a report by the Society of Automotive Engineers (SAE), there are thousands of standardized DTCs, each corresponding to a specific issue. DTCs are typically five-character alphanumeric codes. For example, P0300 indicates a random or multiple cylinder misfire. Mechanics use scan tools to read these codes and consult databases or repair manuals to interpret them and diagnose the problem.
