OBDII Bluetooth adapters have revolutionized vehicle diagnostics, offering car owners and enthusiasts the power to access real-time data and troubleshoot issues directly from their smartphones or tablets. However, establishing this wireless connection requires a crucial step: entering the correct Obdii Bluetooth Adapter Pin Code. This article will guide you through the process of pairing your OBDII adapter, focusing on locating and utilizing the pin code for a smooth and successful connection.
Step 1: Plugging In and Powering Up Your OBDII Adapter
Before you begin the Bluetooth pairing process, ensure your OBDII adapter is correctly installed in your vehicle. Locate the OBDII port, typically found under the dashboard on the driver’s side. Plug your adapter securely into this port.
Once plugged in, turn your vehicle’s ignition to the “ON” position or start the engine. This provides power to the OBDII port and your adapter. If your specific adapter model has a power button, make sure to switch it on as well.
Step 2: Initiating Bluetooth Pairing on Your Phone or Tablet
With your adapter powered and ready, the next step is to pair it with your Android or iOS device via Bluetooth.
-
Access Bluetooth Settings: Navigate to the Bluetooth settings menu on your smartphone or tablet. This is usually found within the main “Settings” app under “Connections” or “Bluetooth.”
-
Enable Bluetooth and Scan: Turn Bluetooth on and initiate a device scan. Your device will begin searching for nearby Bluetooth devices.
-
Locate Your OBDII Adapter: In the list of available devices, look for your OBDII adapter. It often appears with names like “OBDII,” “obd2,” or a name associated with the adapter’s brand, such as “Viecar” or “VLink.” Importantly, it will not be named after your car brand or something generic like “MY CAR.”
Step 3: Entering the OBDII Bluetooth Adapter Pin Code
Once you tap on your OBDII adapter’s name in the device list to initiate pairing, your phone or tablet will prompt you to enter a PIN code. This is where the OBDII Bluetooth adapter pin code becomes essential.
-
Finding Your PIN Code: The PIN code is a security measure to ensure a secure connection. The most common default PIN codes for OBDII Bluetooth adapters are:
- 1234
- 0000
- 7890
- 1111
Check Your Adapter’s Documentation: If none of these common PIN codes work, your adapter’s documentation is the definitive source for the correct pin code. This documentation usually comes with the adapter, either as a physical manual or a digital guide. Look for sections on Bluetooth pairing or troubleshooting.

- Entering the PIN: Carefully enter the PIN code using the on-screen keypad and confirm the pairing request.
Step 4: Selecting Your Adapter in Diagnostic Software
After successful Bluetooth pairing at the system level, you need to select your adapter within your chosen OBDII diagnostic app (like Car Scanner, Torque Pro, or Autel MaxiAP200).
-
Open App Settings: Launch your diagnostic app and navigate to its settings menu. Look for options like “Adapter,” “Connection,” or “Vehicle Communication.”
-
Choose Connection Type: Select “Bluetooth” as your connection type.
-
Select Device: Tap on an option like “Select Device” or “Bluetooth Device List.” The app will display a list of paired Bluetooth devices. Choose your OBDII adapter from this list.

Connecting and Diagnosing
Once you’ve selected your adapter within the app, you should be ready to connect to your vehicle’s systems. Look for a “Connect” button or similar option within the app. With a successful connection, you can now utilize the app’s features to read fault codes, monitor live data, and perform various diagnostic functions.
Troubleshooting Tips
- Incorrect PIN Code: Double-check the common PIN codes and your adapter’s documentation. Ensure you are entering the PIN correctly.
- Bluetooth Issues: Make sure Bluetooth is enabled on both your device and the adapter (if it has a power switch). Restart Bluetooth on your phone/tablet or even reboot your device.
- Adapter Compatibility: Verify that your OBDII adapter is compatible with your vehicle and the diagnostic app you are using.
Conclusion
The OBDII Bluetooth adapter pin code is a small but critical detail in establishing a wireless diagnostic connection. By understanding the pairing process, knowing common PIN codes, and consulting your adapter’s documentation, you can overcome this hurdle and unlock the powerful diagnostic capabilities of your OBDII Bluetooth adapter, empowering you to better understand and maintain your vehicle.
