Live Data Stream
Real-time information from vehicle sensors displayed via a scan tool.
Live data shows continuously updated sensor readings like RPM, coolant temperature, throttle position, and fuel trims. Technicians use it to diagnose issues that don't trigger DTCs. Comparing data across sensors helps detect performance irregularities or intermittent faults. A clear live data stream indicates healthy ECU communication. Modern scan tools allow graphing and recording data for analysis. This feature greatly enhances diagnostic accuracy and time efficiency.
