A Bluetooth OBDII scan tool, like the BAFX Products ELM327, paired with the Torque Pro app, offers a powerful and affordable solution for monitoring your vehicle’s performance and diagnosing engine trouble codes. This guide provides a step-by-step walkthrough on how to connect and use these tools with your vehicle.
Connecting the BAFX Bluetooth OBDII Scanner

-
Plug in the Scanner: Insert the BAFX Bluetooth OBDII scanner into the OBDII port. The scanner’s LED should light up, indicating power and connection.
-
Enable Bluetooth: On your Android device, turn on Bluetooth and search for available devices. The BAFX scanner should appear as “OBDII” or a similar name.

Pair the Devices: Select the “OBDII” device and enter the pairing code. The default code is often “1234,” “0000,” or “5678.” Your phone will confirm a successful pairing.

Adding Custom PIDs for GM Vehicles
