Step 1: Enabling Bluetooth on Your Laptop
Before attempting to connect your OBD2 MX Bluetooth adapter, ensure that Bluetooth is enabled on your Windows laptop.
If you are using a USB Bluetooth adapter, you’ll need to install the drivers provided by the manufacturer. Typically, these drivers come with the adapter or are available for download from the manufacturer’s website. Follow their specific instructions for installation.
For laptops with built-in Bluetooth, the process is usually straightforward.
- Access Bluetooth Settings: Click on the Start Menu (Windows icon) and go to Settings (gear icon).
- Navigate to Devices: In the Settings menu, select Devices.
- Turn Bluetooth On: In the Devices menu, find Bluetooth & other devices and ensure the Bluetooth toggle is switched to ‘On’.
Refer to your laptop’s owner’s manual for more detailed instructions if needed, as the exact steps may vary slightly depending on the Windows version and laptop model.
Step 2: Locating the OBD-II Diagnostic Connector in Your Vehicle
The OBD-II (On-Board Diagnostics II) port is a standardized connector in your vehicle, typically used for accessing vehicle system information. Finding this port is crucial for connecting your OBD2 MX Bluetooth adapter.
The diagnostic connector is always located inside the passenger compartment, within easy reach of the driver. While it’s usually exposed for easy access, sometimes it may be hidden by a small plastic cover or located behind an ashtray or coin tray.
The most common location for the OBD-II port is underneath the steering column, in the area below the dashboard on the driver’s side. You may need to look around this area, possibly near the pedals or slightly to the right of the steering column.
Step 3: Plugging in Your OBDLink Adapter
Once you’ve located the OBD-II port, take your OBDLink MX Bluetooth adapter and carefully plug it into the connector.
Ensure the adapter is oriented correctly and push it in firmly but gently. Avoid using excessive force. The adapter should fit snugly into the OBD-II port.
Upon successful connection, the ‘Power’ LED on the OBDLink MX Bluetooth adapter will illuminate solid green, indicating it’s receiving power from the vehicle. For OBDLink Wi-Fi models, the ‘Wi-Fi’ light will flash every 3 seconds.
Step 4: Turning the Ignition to the ‘ON’ Position
To allow the OBDLink adapter to communicate with your vehicle’s computer system, you need to turn the ignition key to the ‘ON’ position. This provides power to the vehicle’s electronic systems without starting the engine.
On many vehicles, the ‘ON’ position is marked with the Roman numeral ‘II’. If there are no markings, turn the key clockwise to the position just before starting the engine. All dashboard lights should illuminate in the ‘ON’ position.
Step 5: Making the OBDLink Adapter Discoverable
To initiate the Bluetooth pairing process, you need to make your OBDLink MX Bluetooth adapter discoverable to your laptop.
Locate the ‘Connect’ button on your OBDLink adapter and press it. Upon pressing the button, the ‘BT’ (Bluetooth) light on the adapter will begin to blink rapidly. This indicates that the adapter is now in pairing mode and is discoverable by Bluetooth devices.
Important: The OBDLink adapter typically remains in discoverable mode for approximately 2 minutes. If the pairing process takes longer, or if it fails initially, you may need to press the ‘Connect’ button again to re-enable discoverable mode.
Step 6: Pairing OBDLink with Your Windows Laptop
Now that your OBDLink adapter is discoverable and your laptop’s Bluetooth is enabled, you can proceed with the Bluetooth pairing process in Windows.
- Access Bluetooth Devices: Open the Windows System Tray, usually located in the bottom right corner of your screen.
- Right-Click Bluetooth Icon: Find the Bluetooth icon in the system tray and right-click on it.
- Select ‘Add a Device’: From the context menu that appears, click on ‘Add a Device’.
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. It will typically be listed as ‘OBDLink’.
- Select OBDLink: Click on ‘OBDLink’ from the list of discovered devices.
- Click ‘Next’: Click the ‘Next’ button to initiate the pairing process.
Bluetooth Pairing Code (PIN):
Depending on your laptop’s Bluetooth adapter, you might encounter different pairing prompts.
- Numeric Comparison: Some newer Bluetooth adapters support Numeric Comparison. If you see a screen asking you to compare pairing codes, simply select ‘Yes’ and click ‘Next’. Ignore any request to compare specific codes.
- PIN Code Request: Older Bluetooth adapters may require a PIN code for pairing. If prompted to enter a PIN, use ‘1234’. If you are given the option to pair without a code, always choose to enter the PIN and use ‘1234’.
Once the pairing process is complete, Windows will display a confirmation message indicating that the OBDLink adapter has been successfully installed and paired with your laptop.
If the OBDLink adapter fails to install correctly, press the ‘Connect’ button on the adapter again to restart discoverable mode and repeat Step 6.
Step 7: Installing the OBDwiz Application
OBDwiz is a diagnostic software application designed to work seamlessly with OBDLink adapters, allowing you to interpret the data from your vehicle. You’ll need to download and install this software on your laptop.
- Download OBDwiz: Go to the OBDwiz download page.
- Run Installer: Download the latest version of OBDwizSetup.exe and run the installer. Follow the on-screen instructions to complete the installation process.
Before proceeding, ensure that you have successfully paired your OBDLink adapter with Windows as outlined in Step 6, and that your vehicle’s ignition is still in the ‘On’ position.
Step 8: Initial Software Setup in OBDwiz
After installing OBDwiz, launch the application. The first step within the software is to configure the connection with your OBDLink adapter.
- Click ‘Auto Detect’: In the OBDwiz application, locate and click the ‘Auto Detect’ button. This is usually prominently displayed on the main screen.
OBDwiz will automatically scan all available COM ports and baud rates to detect and configure itself to communicate with your OBDLink adapter via Bluetooth.
Once the auto-detection process is complete, a dialog box will appear confirming that your OBDLink device has been found and configured successfully.
Step 9: Connecting to Your Vehicle in OBDwiz
With the initial software setup complete, you can now establish a connection between OBDwiz and your vehicle’s computer through the OBDLink adapter.
- Click ‘Connect’: In the OBDwiz application, click the ‘Connect’ button.
OBDwiz will begin cycling through various OBD-II protocols to automatically detect the protocol used by your vehicle. A status screen will display the progress of this automatic protocol detection.
Many modern vehicles have multiple on-board computers (ECUs) connected on the OBD-II network. Since the OBD-II standard only allows connection to one ECU at a time, OBDwiz will often prompt you to choose an ECU.
It’s generally recommended to initially connect to the ECU reporting the most ‘Supported PIDs’ (Parameter IDs), as this usually provides the most comprehensive data. You can always disconnect and reconnect to select a different ECU later. Click ‘Continue’ to proceed after protocol detection.
