4. Turn on your ignition to the “accessory” position. This powers on the scanner without starting the engine. Some cars may require the engine to be running.

Using the Foseal OBD2 App

Once the scanner is connected, you’ll need to pair it with your smartphone or tablet using the Foseal OBD2 app.

1. Download and install the Foseal app. The app is available for both Android and iOS devices.
2. Enable Bluetooth on your device.
3. Open the Foseal app and follow the on-screen instructions to pair it with your scanner. The app will usually search for available devices automatically.

Reading and Understanding OBD2 Codes

With the connection established, you can now start reading and understanding the data from your car’s computer:

1. Read OBD2 codes. The app will display any stored or pending Diagnostic Trouble Codes (DTCs) from your car’s ECU (Engine Control Unit). These codes indicate specific problems within your vehicle’s systems.

2. Interpreting DTCs. Each DTC is a combination of letters and numbers that correspond to a specific issue. You can easily find the meaning of each code:
   • Within the Foseal app: Many apps offer a built-in code library for quick reference.
   • Online OBD2 code databases: Numerous websites provide free and detailed explanations of OBD2 codes.
3. View live data stream. The Foseal app allows you to view real-time data from your car’s sensors, including:
   • Engine RPM
   • Coolant temperature
   • Oxygen sensor readings
   • Vehicle speed
   • And much more!
