1. Connect the scan tool and your smartphone or tablet using the steps mentioned earlier.
2. Open the OBD2 app and navigate to the “DTCs” or “Fault Codes” section.
3. Select “Read Codes”. The app will communicate with your car’s computer and retrieve any stored DTCs.
4. Interpret the DTCs: The app will display the code and its description. You can search online for more information about each DTC.
5. Clear the codes: After addressing the underlying issue, you can use the app to clear the DTCs from your car’s computer.

Note: Clearing the codes without fixing the problem will only temporarily remove the Check Engine Light. The light will return if the issue persists.

Viewing Live Data

The BAFX Bluetooth OBD2 scan tool allows you to monitor various parameters in real time, including:

• Engine RPM: Shows the engine’s speed in revolutions per minute.
• Vehicle Speed: Displays the current speed of your vehicle.
• Coolant Temperature: Monitors the engine coolant temperature to prevent overheating.
• Intake Air Temperature: Measures the temperature of the air entering the engine.
• Oxygen Sensor Readings: Provides data from the oxygen sensors, which help regulate the air-fuel mixture.

To view live data:

1. Connect your scan tool and open the OBD2 app.
2. Navigate to the “Live Data” or “Sensors” section.
