Connecting your OBD II scanner to your smartphone or tablet via Bluetooth opens up a world of vehicle diagnostics and performance monitoring. A common step in this process is pairing your devices, and you might be prompted for a Bluetooth password. This guide will walk you through finding and using the correct password to establish a seamless connection with your OBD2 scanner.
Step-by-Step Bluetooth Pairing for Your OBD2 Scanner
Pairing your Bluetooth OBD2 scanner is generally a straightforward process. If you’ve already paired your scanner with your device, you can skip directly to step #2 for app connection.
Step #1: Initiate Bluetooth Pairing on Your Android Device
For new connections, you’ll first need to pair your Android phone or tablet with the OBD2 adapter via Bluetooth.
Note: The exact steps may slightly vary depending on your Android version and device manufacturer.
- Navigate to your device’s settings menu and locate the “Bluetooth” section.
- Ensure Bluetooth is turned “On.” Your device will begin scanning for nearby Bluetooth devices.
- Your OBD2 adapter should appear in the list of available devices. It’s often identified as “OBDII,” “obd2,” or a similar designation. If your adapter has a brand name (like “Viecar” or “VLink”), it might be listed under that name. Crucially, it will not be named after your car brand or something generic like “MY CAR.”
- Tap on your OBD2 adapter’s name to initiate the pairing process. You will then be prompted to enter a PIN code or Bluetooth password.
Finding Your Obd Ii Scanner Bluetooth Password
The Bluetooth password, or PIN code, is essential for secure pairing. If you’re unsure of the password, here are the most common default PINs used for OBD2 Bluetooth scanners:
- “1234”
- “0000”
- “7890”
- “1111”
These are the most frequently used default passwords. However, always check the documentation that came with your specific OBD2 scanner. The correct Bluetooth password should be listed in the user manual or on a quick start guide. If you cannot locate the documentation, try each of the common PIN codes listed above. One of them will likely be the correct “obd ii scanner bluetooth password” for your device.
Connecting Your OBD2 Scanner within the Car Scanner App
Once your device is paired with the OBD2 adapter via Bluetooth, the next step is to establish the connection within your car diagnostic app, such as Car Scanner.
Step #2: Select Your OBD2 Adapter in the Car Scanner App
- Open the Car Scanner app on your device.
- Access the app’s settings menu. This is usually represented by a gear icon, often located in the top-right corner of the screen.
- Look for a setting labeled “Adapter” or, in older versions of the app, “Connection.” Tap on this option.
- Within the connection settings, select “Bluetooth” as the connection type.
- Tap on “Select device.” This will display a list of available Bluetooth devices that your phone has paired with.
- Choose your OBD2 adapter from the list. It should appear with the same name you noted during the initial Bluetooth pairing step.
After selecting your adapter, navigate back to the main screen of the Car Scanner app and tap the large, prominent “Connect” button. With your OBD2 scanner Bluetooth password correctly entered during device pairing and the adapter selected in the app, you should now be successfully connected and ready to diagnose your vehicle!
For subsequent uses, simply ensure your OBD2 adapter is powered on (if it has a power button) and tap the “Connect” button in your Car Scanner app. The Bluetooth connection should establish automatically, allowing you to quickly access your vehicle’s data.
