Setup Guide
Follow these steps to set up your KUULAA Bluetooth OBD2 Scanner:
- Step 1: Install the Application (App)
For iOS users, it is recommended to use "Car Scanner" or "OBD Car Doctor". For Android users, "Torque" or "OBD Car Doctor" are recommended. You can search for these applications in the Google Play Store or Apple App Store. Alternatively, scan the QR code provided in your product instruction manual or visit http://www.elm327.com/app/ to download the appropriate app. - Step 2: Plug In the Adapter
Locate your vehicle's OBDII port. Most connectors are found under the dashboard, typically near the steering wheel. Refer to your vehicle's manual if you cannot find it. Once located, firmly plug the OBDII scanner into the port. The power light on the scanner should illuminate, indicating it is receiving power. - Step 3: Pair Bluetooth
Turn on the Bluetooth function on your mobile phone. Open the downloaded OBDII application. Within the app, navigate to the connection settings and select the Bluetooth connection method. Search for the OBDII device (it may appear as "OBDII" or a similar name) and pair with it. - Step 4: Connect Automatically
After the initial setup and successful pairing, the product should connect automatically when plugged into the car's standard OBDII interface and the car's ignition is turned on. You will not need to verify the connection again for subsequent uses.

Operating Instructions
Once connected, your KUULAA Bluetooth OBD2 Scanner allows you to perform various diagnostic functions through the chosen mobile application.
Reading and Clearing Diagnostic Codes
The primary function of the scanner is to read and clear Diagnostic Trouble Codes (DTCs). These codes indicate issues detected by your vehicle's onboard diagnostic system.
- Open the "Diagnostic Trouble Codes" or "Fault Codes" icon within your app.
- The app will scan for active and pending DTCs.
- View the relevant data and descriptions to understand the cause of the fault.
- If the issue has been resolved or you wish to clear the code (e.g., after minor maintenance), select the "Clear DTC" or "Clear error diagnostic code" option. Note: Clearing codes without addressing the underlying issue will likely result in the code reappearing.

Monitoring Vehicle Health and Data
The scanner provides real-time data monitoring, allowing you to observe various vehicle parameters.
- Diagnosis Vehicle Health: Open the "Test Results" or similar icon to view real-time monitoring of various diagnostic values. The database contains over 3000 code definitions to help interpret results. This includes data such as long-term fuel situation, intake manifold pressure, fuel injection advance time, air temperature, air velocity, fuel system status, and fuel consumption monitoring.
- Detect Fuel Consumption and Mileage: Access the "Dashboard" or "Realtime Information" icon to display real-time vehicle fuel quantity, vehicle speed, rotation speed (RPM), mileage, temperature, air pressure, and other data. This allows you to master all vehicle data.
- Additional Functions: Depending on your chosen app, you may also access functions such as "Live Data", "Freeze Frame", "Noncontinuous Monitors", "Acceleration Tests", "Emission Tests", "Data Recording", "Map View", "Graphing", and "Adapter Status".

Troubleshooting
If you encounter issues with your KUULAA Bluetooth OBD2 Scanner, try the following solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner not powering on. | Not properly plugged into OBDII port; vehicle ignition off; vehicle's OBDII port fuse blown. | Ensure the scanner is fully inserted. Turn the vehicle ignition to the ON position. Check your vehicle's fuse box for a blown fuse related to the OBDII port. |
| Cannot connect via Bluetooth. | Bluetooth not enabled on phone; incorrect pairing process; app compatibility issue. | Verify Bluetooth is enabled on your phone. Ensure you are pairing within the app's settings, not just phone's Bluetooth settings. Try a different recommended app. Restart both phone and scanner. |
| App not displaying data or showing errors. | Loose connection; app settings incorrect; vehicle not OBDII compliant. | Check the scanner's connection to the OBDII port. Verify app settings (e.g., correct protocol selected). Ensure your vehicle is OBDII compliant (most vehicles from 1996 onwards are). |
| Slow data refresh rate. | App settings; phone performance. | Check app settings for data refresh rate options. Close other apps running in the background on your phone. |
