  • Read fault codes: When something goes wrong, your car’s ECU stores a specific code that indicates the nature of the problem.
  • Analyze data: Real-time data from various sensors throughout your car provides insights into its performance and potential issues.
  • Run tests: Specific tests can be initiated to pinpoint the root cause of a problem.
