5. Setup
The OBD2 Scanner is designed for plug-and-play operation. No batteries or chargers are required as it draws power directly from the vehicle's OBD2 port.
5.1 Connecting to the Vehicle
- Locate the vehicle's 16-pin Data Link Connector (DLC). This is usually located under the dashboard on the driver's side.
- Ensure the vehicle's ignition is OFF.
- Firmly plug the scanner's OBDII connector into the vehicle's DLC.
- Turn the vehicle's ignition to the ON position (engine can be off or running, depending on the test). The scanner will power on automatically.
6. Operating Instructions
The YM119 scanner provides comprehensive OBD2 diagnostic functions. Navigate through the menus using the directional buttons and confirm selections with the 'OK' button.
6.1 Full OBDII Modes
The scanner supports all OBD2 functions:
- Read & Clear Codes: Retrieve and erase Diagnostic Trouble Codes (DTCs) to turn off the Check Engine Light (MIL).
- View Freeze Frame: Display a snapshot of the vehicle's operating conditions at the time a fault code was set.
- Live Data Stream: View real-time sensor data in text and graph format.
- O2 Sensor Test: Retrieve O2 sensor monitor test results.
- Onboard Monitoring Mode: Retrieve results for emission-related powertrain components and systems that are not continuously monitored.
- Component Testing: Allows initiation of a leak test for the vehicle's EVAP system.

6.5 Retrieve Vehicle Information
The scanner can retrieve Vehicle Identification Number (VIN), Calibration ID(s), and Calibration Verification Numbers (CVNs). This function is useful for verifying if the Engine Control Unit (ECU) matches your vehicle.
6.6 User Interface and Visual Indicators
The scanner features visual indicator lights to provide quick insights into your car's health:
- Green: Indicates a good connection and no immediate faults.
- Yellow: Suggests incompatibilities or conditions that need attention.
- Red: Signals faults or conditions requiring immediate action.
