1. Understanding Auto Diagnostics

Auto diagnostics involves identifying problems within a vehicle’s systems using electronic scan tools and software. These tools interface with the car’s onboard computer to read diagnostic trouble codes (DTCs), providing insights into potential issues.

1.1. What is Auto Diagnostics?

Auto diagnostics is the process of identifying malfunctions in a vehicle’s engine, transmission, exhaust system, and other components. Modern vehicles are equipped with onboard computers and numerous sensors that continuously monitor the performance of these systems. When a sensor detects a problem, it sends a signal to the computer, which then stores a diagnostic trouble code (DTC).

According to a study by the National Institute for Automotive Service Excellence (ASE), understanding DTCs is crucial for accurate and efficient vehicle repairs. The ASE emphasizes the importance of using proper diagnostic tools and following standardized procedures to ensure that repairs are done correctly the first time.
