The Innova 3100 is able to display live data, refreshing every 30 seconds to ensure reliable data in real time. This data can then be frozen if desired, freeze frame data is useful for note taking and analytics. The live data can then be used to confirm repair completion, as it will show whether the error has been fixed. This is particularly valuable where there are multiple issues, meaning that the check engine light cannot be used alone. By highlighting the root cause of issues, this scan tool will enable its user to fix issues and see their progress in real time.
