4. 設定

The Riokko YM119 scanner is designed for quick and easy setup. No batteries are required as it draws power directly from the vehicle's OBDII port.

連接掃描器：

1. Locate the vehicle's 16-pin Data Link Connector (DLC). The DLC is usually located under the dashboard on the driver's side. Refer to your vehicle's service manual for the exact location if you cannot find it.
2. Turn the vehicle's ignition to the OFF position.
3. 將掃描器的 OBDII 連接器牢固地插入車輛的 DLC 介面。
4. Turn the vehicle's ignition to the ON position (engine off). The scanner will automatically power on and display the main menu.

Note: If the scanner does not power on, ensure the connection is secure and check the vehicle's fuse for the OBDII port.

5. 操作說明

Once the scanner is connected and powered on, you can navigate through the main menu using the UP, DOWN, LEFT, RIGHT, OK, and EXIT buttons.

5.1. Diagnosis Menu

From the main menu, select 'Diagnosis' and press OK to enter the diagnostic functions.

• 閱讀代碼：

  This function reads the Diagnostic Trouble Codes (DTCs) stored in the vehicle's Engine Control Unit (ECU). These codes indicate specific issues detected by the vehicle's onboard diagnostic system.

  1. Select 'Read Codes' and press OK.
  2. The scanner will display any stored Pending, Confirmed, or Permanent DTCs.
  3. Use UP/DOWN to scroll through codes if multiple are present.
• 擦除程式碼：

  This function clears all stored DTCs from the vehicle's ECU and turns off the Malfunction Indicator Lamp （MIL），也稱為引擎故障指示燈。 Warning: Clearing codes does not fix the underlying problem. Ensure the issue is resolved before clearing codes, or the light will likely return.

  

  Figure 5.2: Check and Turn Off Engine Light. This image demonstrates the scanner's ability to diagnose and clear the engine fault light, showing a dashboard with the engine light illuminated before diagnosis and off after the fault is cleared.

  1. Select 'Erase Codes' and press OK.
  2. 出現提示時確認您的選擇。
  3. The MIL will turn off, and DTCs will be cleared.
