3. Setup

The EDIAG YA-201 is designed for immediate use with its plug-and-play functionality. No complex setup or external power source is required.

1. Locate the OBDII Port: The 16-pin OBDII Data Link Connector (DLC) is typically located under the dashboard on the driver's side of the vehicle. Refer to your vehicle's owner's manual if you cannot locate it.
2. Connect the Scanner: Firmly plug the EDIAG YA-201's OBDII connector into the vehicle's DLC.
3. Power On: Once connected, the scanner will automatically power on and display the main menu. If the device does not power on, ensure the vehicle's ignition is in the "ON" position (engine off or running, depending on the desired test).

4. Operating Instructions

Navigate the scanner's menu using the directional buttons (Up, Down, Left, Right) and the OK/Enter button. The Return button allows you to go back to the previous screen.

4.1 Main Menu Options

• Diagnosis: Accesses the primary OBDII diagnostic functions.
• DTC Lookup: Provides definitions for Diagnostic Trouble Codes.
• Battery: Checks the vehicle's battery voltage.
• Settings: Configures device preferences.

4.2 Diagnostic Functions

From the main menu, select "Diagnosis" and press OK to access the following functions:

• Read Codes (DTCs):

  Retrieves Diagnostic Trouble Codes from the vehicle's Engine Control Unit (ECU). Codes are categorized as:

  • Stored Codes: Confirmed fault codes that have illuminated the Malfunction Indicator Lamp (MIL).
  • Pending Codes: Faults detected during the current or last driving cycle that have not yet illuminated the MIL.
  • Permanent Codes: Codes that cannot be cleared by simply erasing DTCs. They clear only after the fault is confirmed to be fixed by the ECU through driving cycles.
• Erase Codes:

  Clears all Diagnostic Trouble Codes from the vehicle's ECU and turns off the Malfunction Indicator Lamp (MIL). Note: Erasing codes does not fix the underlying problem. The MIL will re-illuminate if the fault persists.

• Live Data:

  Displays real-time operating parameters of the vehicle. This function is crucial for diagnosing intermittent problems and verifying repairs.

  • All Datastream: Shows all available live data parameters in text format.
  • Graph Display: Presents selected live data parameters in a graphical format for easier analysis of trends and fluctuations.
  • Record: Allows recording of live data for later review.
  • Playback: Reviews previously recorded live data.

• Freeze Frame:

  Captures a snapshot of vehicle operating conditions at the moment a fault code is set. This data helps in determining the cause of the fault.

• I/M Readiness:

  Indicates whether the various emission-related systems on the vehicle are operating correctly and have completed their diagnostic tests. This is essential for emissions testing.

• Mode 6 (On-board Monitoring Test):

  Accesses the results of on-board diagnostic monitoring tests for specific components/systems that are not continuously monitored. This includes misfire cylinder data.

• O2 Sensor Test:

  Retrieves O2 sensor monitoring test results for the most recently completed tests from the vehicle's on-board computer.

• EVAP Systems (Mode 8) Component Test:

  Allows initiation of a leak test for the vehicle's EVAP (Evaporative Emission Control) system.

• Vehicle Information:

  Displays the vehicle's Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN).

4.3 DTC Lookup

Select "DTC Lookup" from the main menu. Enter the 5-digit code to view its definition directly on the screen, saving time from searching online.

4.4 Battery Test

Select "Battery" from the main menu to view the real-time voltage of the car battery. This feature helps in monitoring battery health and determining if a replacement is needed.

4.5 Settings

Select "Settings" from the main menu to customize the device:

• Language: Change the display language.
• Unit: Switch between Metric and Imperial units for data display.

6. Maintenance

To ensure the longevity and optimal performance of your EDIAG YA-201 scanner, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the device. Avoid using abrasive cleaners or solvents.
• Storage: Store the scanner in a clean, dry environment away from extreme temperatures and direct sunlight.
• Software Updates: The EDIAG YA-201 offers lifetime free software updates. Regularly check for and install updates to ensure compatibility with newer vehicles and access to improved features. Refer to the manufacturer's website for update instructions.

7. Troubleshooting

If you encounter issues with your EDIAG YA-201, consider the following common troubleshooting steps:

• No Power/Display:
  • Ensure the OBDII connector is firmly plugged into the vehicle's DLC.
  • Verify the vehicle's ignition is in the "ON" position.
  • Check the vehicle's fuse for the OBDII port (usually labeled "CIGAR" or "AUX POWER").
• Communication Error:
  • Confirm the vehicle supports the OBDII protocol (most vehicles after 1996 do).
  • Ensure the ignition is "ON" or the engine is running.
  • Try connecting the scanner to a different OBDII-compliant vehicle to rule out a scanner issue.
  • Check for any loose connections or damaged cables.
• Codes Not Clearing:
  • Ensure the underlying fault has been repaired. Codes will reappear if the problem persists.
  • Some permanent codes require multiple drive cycles to clear after a repair.
