Connecting your Windows laptop to your car’s onboard diagnostics (OBD) system is now easier than ever with an Obd2 Bluetooth Driver. This guide provides a step-by-step walkthrough on how to pair your ELM327 Bluetooth scanner with your Windows system and establish a successful connection with OBD-II software.
Pairing Your OBD2 Bluetooth Scanner
Before you begin, ensure your ELM327 Bluetooth OBD2 scanner is powered on (indicated by a red light). Here’s a detailed guide to pairing your scanner with Windows:
Step 1: Connect to the OBD Port
Locate your car’s OBD-II port, typically found under the steering wheel on the driver’s side. Plug the OBD2 Bluetooth scanner into this port.
Step 2: Turn on the Ignition
Turn your car’s ignition on, one step before starting the engine. This powers the OBD-II system.
Step 3: Add the Bluetooth Device in Windows
- Right-click the Bluetooth icon in your system tray and select “Add a Device.”

- Look for your ELM327 device. It might appear under various names (OBDII, OBD-II, VLink, Can OBDII, etc.). Be patient, as the signal can take up to 15 seconds to appear.
Troubleshooting:
- Signal Not Showing: Try disconnecting and reconnecting the scanner. Restarting your computer can also help. If the scanner’s red power light is on, it’s working and should be detectable.
- Already Paired: If you’ve previously paired the device, look for it under “Show Bluetooth Devices” instead of “Add a Device.”
- Select your ELM327 device and enter the pairing code. Common codes include 1234 or 0000.
(Windows XP Users): Note the outgoing COM port number assigned to the device during the pairing process. You’ll need this to configure your OBD software.
Launching Your OBD Software
Step 4: Connect to Your Vehicle
Open your chosen OBD-II software. Click the “Connect” button. The software should automatically detect and connect to your ELM327 OBD2 Bluetooth adapter.
Troubleshooting Connection Issues
If connection problems arise, try these solutions:
-
Adjust Baud Rate: Within your OBD software’s settings, try setting the baud rate to 9600 or 110.
-
Manually Set Baud Rate (if software lacks the option):
- Open Device Manager (search for it in the Windows search bar).
- Expand “Ports (COM & LPT).”
- Right-click on “Standard Serial over Bluetooth link” (or a similar name).
- Select “Properties,” then navigate to the “Port Settings” tab.
- Lower the “Bits per second” to 110. Click “OK.”
By following these steps, you can successfully connect your Windows computer to your vehicle using an OBD2 Bluetooth driver and unlock valuable diagnostic information. Remember to consult your OBD software’s documentation for specific instructions.
