Locating Your OBD2 Port

The OBD2 port is a standardized 16-pin connector typically located under the dashboard on the driver’s side. Sometimes, it can be hidden behind a panel or near the steering column. Consult your vehicle’s owner’s manual if you’re having trouble finding it.

Connecting the OBD2 Bluetooth Scanner

Once you’ve located the OBD2 port, simply plug in your Bluetooth scanner. Most scanners power on automatically when connected to the port, indicated by an LED light. However, some may have a separate power button. Check your device’s manual for specific instructions.

Pairing Your Scanner

With the scanner plugged in and powered on, activate Bluetooth on your smartphone, tablet, or laptop. Search for available devices. Your OBD2 scanner should appear in the list, often with a name similar to its model number. Select the scanner and enter the pairing code if prompted (usually “0000” or “1234,” but refer to your scanner’s manual for the correct code).
