2. Playback, Print, and Record Data History

Playback Data History: Review historical data including fault codes, VIN, On-Board Monitoring results, Component Test outcomes, O2 Sensor Test results, I/M Readiness status, Freeze Frame data, and Live Data.

Print Data: Use the screenshot function to capture and print needed diagnostic data.

Read VIN: The YA-201 code reader retrieves vehicle identification information directly from the vehicle’s system.

3. Battery Voltage Monitoring with Graphical Display

Battery Voltage Data Test: Monitors real-time battery voltage status.

Early Warning Capability: Technicians recommend performing a battery test before diagnosis to improve diagnostic accuracy and receive early warnings about potential electrical issues.
