Connecting a mini OBD2 Bluetooth adapter to your smartphone or tablet is a simple yet powerful way to access your car’s diagnostic data. This allows you to read error codes, monitor engine performance, and gain valuable insights into your vehicle’s health, right from your mobile device. This guide will walk you through the process of pairing your mini OBD2 adapter via Bluetooth, focusing on the essential Mini Obd2 Bluetooth Pin for a successful connection.
Step 1: Plugging In Your Mini OBD2 Bluetooth Adapter
First, locate the OBDII diagnostic socket in your vehicle. This is typically found under the dashboard on the driver’s side, but its exact location can vary depending on your car’s make and model. Consult your vehicle’s owner’s manual if you are unsure.
Once you’ve found the socket, carefully plug in your mini OBD2 Bluetooth adapter. Ensure it is firmly seated. If your adapter has a power button, you may need to press it to activate the device. You should also turn your car’s ignition to the “ON” position (or start the engine) to provide power to the OBDII port.

Step 2: Pairing Your Device via Bluetooth
Now, you need to establish a Bluetooth connection between your smartphone or tablet and the OBD2 adapter.
Access Bluetooth Settings:
Navigate to the Bluetooth settings menu on your Android or iOS device. Ensure Bluetooth is turned on and your device is set to scan for available devices.
Discovering Your OBD2 Adapter:
Your device should begin searching for nearby Bluetooth devices. Look for a device name that is typically indicative of an OBD2 adapter. Common names include “OBDII”, “obd2”, or brand-specific names like “Viecar” or “VLink”. It’s important to note that the adapter’s name will never be related to your car’s brand or model, such as “My Car” or “Toyota Bluetooth.”

Entering the Bluetooth PIN:
Once you locate your OBD2 adapter in the device list, tap on it to initiate the pairing process. You will be prompted to enter a mini obd2 bluetooth pin. This PIN code is crucial for secure Bluetooth pairing.
Finding Your OBD2 Bluetooth PIN:
The mini obd2 bluetooth pin is not a universal code and varies depending on the manufacturer of your OBD2 adapter. The most common PIN codes are:
- 1234
- 0000
- 7890
- 1111
Refer to the documentation that came with your mini OBD2 Bluetooth adapter. The PIN code should be specified in the user manual or on a separate card included in the packaging. If you cannot find the documentation, try the common PIN codes listed above, starting with “1234”.

Successful Pairing:
Enter the correct mini obd2 bluetooth pin when prompted by your device. If the PIN is correct, your device will successfully pair with the OBD2 adapter. You may see a “Paired” or “Connected” status next to the adapter’s name in your Bluetooth settings.
Step 3: Selecting the Adapter in Your Car Scanner App
With Bluetooth pairing complete, the final step is to configure your car scanner app to connect to your newly paired OBD2 adapter.
Open Car Scanner App Settings:
Launch your chosen car scanner application (like Car Scanner ELM OBD2, Torque Pro, etc.) on your smartphone or tablet. Navigate to the app’s settings menu. This is usually represented by a gear icon or found within the app’s menu options.
Adapter or Connection Settings:
Within the app settings, look for a section labeled “Adapter”, “Connection”, or “Connectivity”. Tap on this section to access the adapter selection options.
Choose Bluetooth Connection Type:
Select “Bluetooth” as the connection type within the app’s adapter settings.
Select Your OBD2 Adapter Device:
The app should now display a list of available Bluetooth devices. Tap on the name of your OBD2 adapter that you previously paired in your device’s Bluetooth settings.

Connect and Start Scanning:
Once you have selected your adapter within the app, navigate back to the main screen of the car scanner app. You should now see a “Connect” button, often prominently displayed and green in color. Tap this button to establish a connection between the app and your OBD2 adapter.
With a successful connection, your car scanner app will now be able to communicate with your vehicle’s computer through the mini OBD2 Bluetooth adapter. You can start scanning for diagnostic trouble codes (DTCs), monitor real-time engine data, and utilize the various features of your chosen car scanner app.
Troubleshooting Tips:
- Incorrect PIN: If pairing fails, double-check the mini obd2 bluetooth pin from your adapter’s documentation and try again.
- Adapter Not Discoverable: Ensure your adapter is powered on (if it has a power button) and plugged in correctly. Restart Bluetooth on your device and try scanning again.
- App Compatibility: Verify that your car scanner app is compatible with Bluetooth OBD2 adapters and that you have selected the correct adapter in the app settings.
By following these steps and correctly entering your mini obd2 bluetooth pin, you’ll be well on your way to diagnosing and understanding your vehicle’s performance using a mini OBD2 Bluetooth adapter and your smartphone or tablet.
