Step 3: Find Your OBD2 Bluetooth Scanner PIN Code
When your OBD2 adapter appears, it will likely be listed as “OBDII”, “obd2”, or a brand-specific name like “Viecar” or “VLink”. It is important to note that it will not be named after your car brand or something generic like “MY CAR”. Tap on the adapter’s name to initiate pairing. You will be prompted to enter a PIN code.

Step 4: Select Your Adapter in the Car Scanner App
With Bluetooth pairing complete, open your Car Scanner app and access the app’s settings. This is usually represented by a gear icon, often located in the top-right corner of the app interface.
