4. Setup

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.

Connecting the Scanner:

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. Firmly plug the scanner's OBDII connector into the vehicle's DLC.
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. Operating Instructions

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.

Figure 5.1: OBD II Diagnostic Test Items. This image displays the scanner's menu, showing various diagnostic options such as Read Codes, Erase Codes, View Freeze Frame, I/M Readiness, Vehicle Information, Live PCM Data, Realtime Curve, O2 Sensor Test, On-board Mon. Test, and Component Test.

5.1. Diagnosis Menu

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

• Read Codes:

  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.
• Erase Codes:

  This function clears all stored DTCs from the vehicle's ECU and turns off the Malfunction Indicator Lamp (MIL), also known as the Check Engine Light. 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. Confirm your choice when prompted.
  3. The MIL will turn off, and DTCs will be cleared.
• View Freeze Frame:

  Freeze Frame Data is a snapshot of sensor values recorded by the ECU at the moment a DTC was set. This data can help identify the conditions under which the fault occurred.

  

  Figure 5.3: View Freeze Frame and DTCs. This image shows the scanner's display for Freeze Frame data, including parameters like LOAD_PCT, ECT, MAP, RPM, VSS, and MAF, along with a section for 'Since DTCs Cleared' showing monitor status.

  1. Select 'View Freeze Frame' and press OK.
  2. The scanner will display the recorded parameters. Use UP/DOWN to scroll.
• I/M Readiness:

  I/M Readiness (Inspection/Maintenance Readiness) indicates whether the various emissions-related systems on the vehicle are operating correctly and have completed their self-tests. This is crucial for emissions testing.

  1. Select 'I/M Readiness' and press OK.
  2. The scanner will display the status of various monitors (e.g., Misfire Monitor, Fuel System Monitor, Catalyst Monitor) as 'OK' (complete) or 'INC' (incomplete).
• Live PCM Data:

  This function displays real-time operational parameters from the vehicle's Powertrain Control Module (PCM). This data can be viewed as numerical values or graphical curves.

  

  Figure 5.4: Real-time Data Stream. This image shows the scanner displaying live PCM data, with multiple parameters listed numerically and a section for 'Realtime Curve' indicating graphical representation of data.

  1. Select 'Live PCM Data' and press OK.
  2. Choose 'View Data' for numerical values or 'Graph Data' for graphical representation (if available for the parameter).
  3. Use UP/DOWN to scroll through parameters.
• Vehicle Information:

  Retrieves vehicle information such as Vehicle Identification Number (VIN), Calibration ID (CIN), and Calibration Verification Number (CVN).

  1. Select 'Vehicle Information' and press OK.
  2. The scanner will display the available information.
• O2 Sensor Test:

  Monitors the results of oxygen sensor tests.

  1. Select 'O2 Sensor Test' and press OK.
  2. View the test results.
• On-Board Monitor Test:

  Retrieves test results for emission-related powertrain components and systems that are not continuously monitored.

  1. Select 'On-Board Mon. Test' and press OK.
  2. View the test results.
• Component Test:

  Allows for testing of specific components or systems by initiating an on-demand test.

  1. Select 'Component Test' and press OK.
  2. Follow on-screen prompts to perform the test.

5.2. Battery Test

The YM119 can perform a quick test of the vehicle's battery voltage.

2. The scanner will display the current battery voltage.

5.3. DTC Lib (DTC Library)

This function allows you to look up the definition of a Diagnostic Trouble Code (DTC).

1. From the main menu, select 'DTC Lib' and press OK.
2. Enter the DTC using the navigation buttons (UP/DOWN for numbers, LEFT/RIGHT to move cursor).
3. Press OK to view the definition of the code.

5.4. Setting

The 'Setting' menu allows you to customize various scanner preferences.
