5.3. Selecting Your Vehicle

In the diagnostic software, select your vehicle’s make, model, and year. This will ensure that the software can properly communicate with your vehicle’s systems.

5.4. Reading Diagnostic Trouble Codes (DTCs)

Once you’ve selected your vehicle, you can start reading diagnostic trouble codes (DTCs). The software will display a list of any stored, pending, or permanent DTCs. Each DTC has a code and a description that can help you identify the problem.

5.5. Interpreting the Codes

Use the DTC descriptions and other information to interpret the codes and diagnose the problem. You can also use online resources and repair manuals to get more information about the codes and their possible causes.

5.6. Clearing the Codes

Once you’ve diagnosed and repaired the problem, you can clear the DTCs using the diagnostic software. Clearing the codes will turn off the check engine light and reset the vehicle’s diagnostic system. According to research from the University of Texas at Austin, clearing codes without fixing the underlying issue can lead to recurring problems and inaccurate diagnostics.

5.7. Monitoring Real-Time Data

Diagnostic software can also be used to monitor real-time data from your vehicle’s sensors. This can be useful for diagnosing intermittent problems or for monitoring the performance of your vehicle’s systems.

5.8. Performing Component Tests
