4. Setup

The YM319 scanner is a plug-and-play device that does not require batteries or external charging. It draws power directly from the vehicle's OBDII port.

4.1 Connecting the Scanner

1. Locate the vehicle's 16-pin Data Link Connector (DLC). This port is typically found under the dashboard on the driver's side.
2. Ensure the vehicle's ignition is in the 'OFF' position.
3. Firmly plug the YM319 scanner's OBDII connector into the vehicle's DLC.
4. Turn the vehicle's ignition to the 'ON' position (engine can be off or running, depending on the diagnostic task). The scanner will power on automatically.

5. Operating Instructions

5.1 Navigating the Menu

• OK Button: Confirms a selection or enters a menu.
• EXIT Button: Returns to the previous menu or exits a function.
• Arrow Keys (Up/Down/Left/Right): Navigate through menu options and data screens.
• F1/F2 Buttons: Customizable shortcut keys for quick access to frequently used functions.

5.2 Main Functions

From the main menu, select the desired function using the arrow keys and press OK.

• Diagnosis: Accesses the primary OBDII diagnostic functions.
  • Read Codes: Displays Diagnostic Trouble Codes (DTCs) stored in the vehicle's computer.
  • Clear Codes: Erases DTCs from the vehicle's computer and turns off the Check Engine Light. Note: Clearing codes does not fix the underlying problem. Address the issue before clearing codes to prevent recurrence.
  • I/M Readiness: Checks the status of the vehicle's emission-related monitoring systems.
  • Live Data Stream: Displays real-time sensor data from the vehicle's engine.
  • Freeze Frame: Shows a snapshot of sensor data at the moment a fault code was set.
  • O2 Sensor Test: Retrieves oxygen sensor monitoring test results.
  • EVAP System Test: Initiates a test of the Evaporative Emission Control System.
  • Vehicle Information: Displays the vehicle's VIN, Calibration ID (CIN), and Calibration Verification Number (CVN).
