Step 4: Turning the Ignition Key to the ‘ON’ Position

To allow the OBDLink to communicate with your vehicle’s computer, you need to turn the ignition key to the ‘ON’ position.

‘ON’ Position Indication: The ‘ON’ position is often marked with the Roman numeral ‘II’ on the ignition switch. If there are no markings, turn the key clockwise to the position just before you would start the engine. This position activates the vehicle’s electrical systems and the OBD-II port, without starting the engine itself.
Avoid Starting the Engine: It’s important to turn the key to ‘ON’ and not start the engine during the initial connection process. This ensures a stable connection and prevents any potential interference from the engine starting sequence.

Step 5: Making OBDLink Discoverable for Pairing

For Bluetooth models, you now need to make your OBDLink device discoverable so your computer can find and connect to it.

Engage Connect Button: Locate the ‘Connect’ button on your OBDLink adapter and press it.
Bluetooth Indicator: Upon pressing the ‘Connect’ button, the ‘BT’ (Bluetooth) light on the OBDLink will start blinking more rapidly. This indicates that the device is in pairing mode and is broadcasting a Bluetooth signal ready to be discovered by your computer.
Time-Sensitive Pairing: Be aware that the OBDLink typically stays in discoverable mode for approximately 2 minutes. This is to enhance security and conserve power.
Re-engaging Discoverable Mode: If the pairing process takes longer than expected, or if the 2-minute window expires, simply press the ‘Connect’ button again to re-activate the discoverable mode and continue with the next step.

Step 6: Pairing OBDLink with Your Windows Computer via Bluetooth

With OBDLink in discoverable mode and Bluetooth enabled on your computer, you can now proceed to pair the devices.

Access Bluetooth Settings: On your Windows computer, locate the System Tray (usually in the bottom right corner of your screen). Find the Bluetooth icon, right-click on it, and select ‘Add a Device’ from the context menu.

Device Discovery: Windows will automatically begin searching for Bluetooth devices in range. After a short scan, your OBDLink device should appear in the list of discovered devices, typically listed as ‘OBDLink’.
Initiate Pairing: Click on the ‘OBDLink’ device name in the list, and then click the ‘Next’ button to start the pairing process.

PIN Code or Numeric Comparison (If Prompted):
- Numeric Comparison: Some newer Bluetooth adapters utilize Numeric Comparison. If you encounter a screen asking you to ‘Compare pairing codes,’ simply select ‘Yes’ and then click ‘Next’. There’s no need to actually compare codes in this case.
- PIN Code Entry: Older Bluetooth adapters may require a PIN code. If prompted to enter a PIN, use ‘1234’. This is the standard PIN for OBDLink devices. If you are given the option to pair without a code, avoid this and choose the PIN entry method for a secure connection.

Successful Pairing Confirmation: Once the pairing is successful, Windows will display a confirmation message indicating that OBDLink has been successfully installed and connected.

Troubleshooting Pairing Issues: If the OBDLink installation is not successful, press the ‘Connect’ button on the OBDLink adapter again to re-initiate discoverable mode and repeat Step 6. Ensure Bluetooth is properly enabled on your computer and that the OBDLink is securely plugged into your vehicle’s OBD-II port.
