3. Data Stream: Reads and displays live ECU/PCM data stream, with graphical plotting functions and storage of freeze frame data.
4. I/M Readiness Status: Shows whether various emissions-related systems are operating correctly and are ready for inspection.
5. Read Live Data Stream: Displays continuous data stream from a vehicle in a live graphic (waveform) format.
6. View Freeze Frame Data: Checks specific vehicle conditions recorded by the on-board computer when an emission-related fault occurs.
7. O2 Sensor Test: Allows retrieval and viewing of O2 sensor monitor test results from recently performed tests.
8. On-Board Monitor Test (Mode 6): Retrieves and displays test results for emission-related powertrain components and systems.
9. Read Vehicle Information: Displays information such as VIN (Vehicle Identification Number), CID (Calibration ID), and CVN (Calibration Verification Number).
10. Component Test (Mode 8): Actuates certain vehicle components via commands from the scanner to test their operability.

3.2 Special Features

• DTC Look Up: Provides definitions for DTCs stored in the scan tool and suggests possible causes.
• Battery Testing: Allows you to check your car's battery status.



• Screenshot Function: Press and hold the up and down buttons for 3 seconds to quickly capture a screenshot of the display.



• Review Back Functions: Record and play back readouts or graphs, useful for diagnosing intermittent problems that do not immediately generate a code.

4. Maintenance

4.1 Lifetime Free Updates

The YA101 offers a lifetime free update service. To update the device, connect it to a PC via the USB cable. A removable disk will appear; simply copy and paste the update files into this disk. No driver installation is required.

5. Troubleshooting

• Device not powering on: Ensure the scanner is correctly and securely connected to the vehicle's 16-pin DLC socket. The device draws power directly from the vehicle.
• No communication with vehicle: Verify that your vehicle supports standard OBD2 protocols and falls within the supported model years (US 1996+, EU 2000+, Japan/Korea 2006+, China 2008+). Some specialized car models or regional variations may not be compatible.
• Incorrect readings or intermittent issues: Utilize the 'Review Back functions' to record and analyze data streams, which can help identify sporadic problems that don't immediately trigger a fault code.
• Unsupported vehicle type: Remember that the YA101 is designed for 12V passenger vehicles only and is not compatible with 24V trucks or heavy-duty vehicles.
