The ELM327 mini OBDII and BAFX products are popular choices for affordable OBD2 scanners. This article guides you through setting up a BAFX ELM327 Bluetooth OBD2 scan tool with a Verizon Droid4 running Android 4.0.4 and the Torque Pro app, providing a practical example of how these tools can be used for vehicle diagnostics. We’ll cover the initial setup, troubleshooting connection issues, and customizing the Torque app to access specific vehicle data like coolant temperature, battery voltage, and knock retard.
Connecting Your BAFX ELM327 to Your Vehicle and Phone
The process begins with plugging the BAFX adapter into the vehicle’s OBDII port with the key in the “on” position (engine off). The device will indicate its readiness with a solid red light. Next, enable Bluetooth on your Android phone and locate the “OBDII” device. The default password is often “1234,” “0000,” or “5678.” Once paired, open the Torque Pro app.
Troubleshooting Connection Issues and Customizing Torque Pro
If the Torque app doesn’t immediately connect to the BAFX adapter, navigate to “OBD2 Adapter Settings” within the app and select “Bluetooth” as the connection type. Choose your “OBDII” device from the list.
Within the “Preferences” menu, consider enabling “Auto Bluetooth On/Off” for convenience. You can also select “Use Vehicle Fuel Level Sensor” for fuel level readings within the app. Avoid enabling unnecessary performance settings to conserve your phone’s battery life. Turbocharged vehicle owners can adjust the “Boost Calculation Method” for accurate boost readings.
Accessing Specific Vehicle Data with GM PIDs
To monitor parameters like coolant temperature and battery voltage, you need to add GM-specific PIDs (Parameter IDs) to Torque Pro. In “Manage Extra PIDs/Sensors,” select “Add Predefined set” and choose “Pontiac/GM.” This will enable the app to display a wider range of vehicle data. Note that some vehicles, like the 1.8L engine discussed in the original article, may not provide specific data points like oil pressure in PSI, only a general “good” or “bad” status.
Conclusion
The BAFX ELM327 Bluetooth OBD2 scanner offers a cost-effective solution for accessing vehicle diagnostic information. When paired with the Torque Pro app and configured correctly, it provides a wealth of data for monitoring engine performance and troubleshooting issues. While specific data availability can vary between vehicle models, understanding the setup process and customization options empowers users to maximize the tool’s potential. Remember to avoid exposing the device to excessive heat, as this can damage its internal components.
