Unlocking the wealth of data your car holds is easier than ever with a Mini OBD2 Bluetooth adapter. These compact devices plug into your car’s OBD2 port and wirelessly transmit diagnostic information to your smartphone or tablet via Bluetooth. A common hurdle for first-time users is understanding the Bluetooth pairing process, specifically the PIN. This guide will walk you through connecting your mini OBD2 Bluetooth adapter, focusing on the essential PIN aspect to get you connected and diagnosing your vehicle in no time.
Pairing Your Mini OBD2 Bluetooth Adapter
Before you can start reading car data, you need to establish a Bluetooth connection between your phone or tablet and the OBD2 adapter. This initial step, known as pairing, is crucial and sometimes requires a PIN. If you’ve already paired your devices, you can skip ahead to the section on selecting the adapter within your car scanning app.
Note: Bluetooth pairing procedures can slightly vary depending on your Android or iOS device version. These steps are generally applicable but consult your device’s manual if you encounter differences.
To begin pairing, first ensure your Mini OBD2 Bluetooth adapter is correctly plugged into your car’s OBDII port. This port is typically located under the dashboard on the driver’s side. Once plugged in, turn your car’s ignition to the “ON” position (you don’t need to start the engine, but power must be supplied to the adapter). If your adapter has a power button, make sure it’s switched on.
Now, navigate to the Bluetooth settings on your Android or iOS device. Enable Bluetooth and wait for your device to scan for and discover nearby Bluetooth devices.

In the list of available devices, you should see your OBD2 adapter. It often appears as “OBDII”, “obd2”, or a similar generic name. If you have a branded adapter, it might display its brand name, such as “Viecar” or “VLink”. It’s important to note that the adapter will not be named after your car brand or something like “MY CAR”.
Tap on the OBD2 adapter’s name to initiate the pairing process. Your device will then prompt you to enter a PIN code to complete the pairing. This is where the “Mini Obd2 Bluetooth Pin” comes into play.
Finding Your Mini OBD2 Bluetooth Adapter PIN
The PIN code is a security measure to ensure you’re connecting to the correct Bluetooth device. If you’re unsure of the PIN for your Mini OBD2 Bluetooth adapter, the first place to check is the documentation that came with your adapter. This could be a small manual, a card, or even printed on the adapter’s packaging.
If you can’t find the documentation, don’t worry. Most Mini OBD2 Bluetooth adapters use a set of common default PIN codes. Try these common PINs:
- 1234
- 0000
- 7890
- 1111
Enter one of these PIN codes when prompted by your device. One of these is likely to be the correct PIN for your adapter. Once you enter the correct PIN, your device should successfully pair with the Mini OBD2 Bluetooth adapter.
Selecting Your Adapter in the Car Scanner App
With Bluetooth pairing complete, the next step is to configure your car diagnostic app, such as Car Scanner, to communicate with your newly paired adapter.
Open the Car Scanner app (or your preferred OBD2 app) and navigate to the app’s settings menu. This is usually represented by a gear icon, often located in the top-right corner of the app’s main screen.
Within the settings menu, look for a section related to “Adapter” or “Connection.” Tap on this option.
This image demonstrates the Car Scanner app’s adapter selection screen, where the user can choose “Bluetooth” as the connection type and select their OBD2 adapter from a list of paired devices.
You’ll typically be presented with a choice of connection types. Select “Bluetooth” as your connection method.
Next, you should see an option like “Select device” or “Choose Bluetooth Device.” Tap on this to display a list of Bluetooth devices that are paired with your phone or tablet.
From the list, select the name of your Mini OBD2 Bluetooth adapter. This is usually the same name you saw during the Bluetooth pairing process (e.g., “OBDII”, “obd2”, “Viecar”, “VLink”).
Once you’ve selected your adapter, you’re almost ready to go. Return to the Car Scanner app’s main screen and tap the large “Connect” button, usually green and prominently displayed.
The app will now attempt to connect to your Mini OBD2 Bluetooth adapter. If everything is set up correctly, you should establish a connection and be able to start scanning your vehicle for diagnostic trouble codes, live data, and much more.
In subsequent uses, as long as your adapter remains paired with your device, you should only need to ensure the adapter is plugged in, powered on (if applicable), and then simply tap the “Connect” button in your Car Scanner app.
By following these steps, understanding the role of the “mini obd2 bluetooth pin,” and using common default PINs if needed, you can easily connect your Mini OBD2 Bluetooth adapter and begin exploring your car’s diagnostic capabilities.
