3.1 Basic OBD-II Functions

With a compatible OBD-II app, the vLinker FD allows you to perform standard diagnostic functions:

• Read Diagnostic Trouble Codes (DTCs): Identify why your check engine light is on.
• Clear DTCs: Turn off the check engine light after resolving an issue.
• View Live Sensor Data: Monitor various vehicle parameters in real-time (e.g., engine RPM, coolant temperature, fuel system status).
• Perform Smog Checks: Check readiness monitors to ensure your vehicle is ready for emissions testing.
• Customize Dashboard: Many apps allow you to personalize the display of live data.

3.2 FORScan Specific Functions

The vLinker FD is optimized for use with FORScan, providing advanced capabilities for Ford, Mazda, Lincoln, and Mercury vehicles:

• Access All Modules: Detect and communicate with modules not visible to generic OBD-II scanners.
• Read and Reset DTCs from All Modules: Gain comprehensive diagnostic coverage beyond the powertrain.
• Unlock Hidden Functions: Enable or disable certain vehicle features (e.g., auto-lock, daytime running lights, tire size correction) as supported by FORScan and your vehicle model.
• Automatic Network Switching: The vLinker FD automatically switches between HS-CAN (High-speed CAN) and MS-CAN (Medium-speed CAN) networks, eliminating the need for a manual toggle switch.

4. Maintenance

The Vgate vLinker FD is designed for minimal maintenance. It is safe to leave the device plugged into your vehicle's OBD-II port when not in use, as it features an automatic sleep mode. The operating current is 51 mA, and the sleep mode current is a low 3mA (minimum), preventing significant battery drain.

• Keep the device clean and free from dust and moisture.
• Store in a cool, dry place when not in use for extended periods.

5. Troubleshooting

If you encounter issues with your vLinker FD, consider the following troubleshooting steps:

• Device Not Powering On: Ensure the vLinker FD is firmly seated in the OBD-II port. Check your vehicle's fuse for the OBD-II port if no lights illuminate.
• Bluetooth Connection Issues:
  • Verify Bluetooth is enabled on your Android/Windows device.
  • Ensure the vLinker FD is discoverable and not already paired with another device.
  • Try unpairing and re-pairing the device.
  • Restart your phone/computer and the vehicle's ignition.
  • Confirm the correct PIN (1234 or 0000) if prompted.
• App Not Connecting to vLinker FD:
  • In your diagnostic app's settings, ensure the vLinker FD (or a generic Bluetooth ELM327 adapter) is selected as the communication interface.
  • Close and reopen the application.
  • Ensure the app has necessary permissions (e.g., Bluetooth, location).
• No Data or Incorrect Readings:
  • Verify your vehicle's ignition is in the ON position (engine can be running for live data).
  • Ensure your vehicle is OBD-II compliant (most vehicles made in the USA after 1996).
  • Check the app's settings for correct vehicle profile or protocol selection.
• Device Not Waking Up (as reported by some users): If the device does not automatically wake from sleep mode when the car powers up, try unplugging and re-plugging the vLinker FD into the OBD-II port.
