Initial Assessment: The mechanic will start by discussing any symptoms or issues you’ve noticed with your vehicle. This information helps them focus on the right areas during the inspection.
Visual Inspection: A thorough visual inspection of the vehicle is conducted to identify any obvious issues, such as leaks, worn belts, or damaged hoses.
Scanning for Error Codes: The mechanic will connect a diagnostic scanner to the vehicle’s onboard computer system. This tool retrieves error codes and data that indicate potential problems within various systems (engine, transmission, etc.).
Data Analysis: The mechanic analyzes the retrieved codes and data, looking for patterns or anomalies that may indicate specific issues. They may cross-reference these codes with repair manuals or databases for accurate diagnosis.
Testing Components: Based on the error codes and visual inspection, the mechanic may perform further tests on specific components, such as sensors, ignition systems, or fuel injectors, to confirm the diagnosis.
