5. Operating Instructions
Once connected, the V020 app provides access to various diagnostic functions. Ensure your vehicle's ignition is in the "ON" position (engine off or running, depending on the test) for accurate readings.
5.1. Reading and Clearing Engine Fault Codes
This function allows you to identify and clear Diagnostic Trouble Codes (DTCs) that trigger the Malfunction Indicator Light (MIL).
- From the main app interface, select "Read Trouble Codes" or a similar option.
- The app will scan the vehicle's systems and display any stored, pending, or permanent DTCs.
- To clear codes, select "Clear Trouble Codes" or "Clear MIL". Confirm the action when prompted. This will turn off the MIL.
Note: Clearing codes only turns off the light; it does not fix the underlying problem. Address the issue before clearing codes to prevent recurrence.

5.2. Vehicle Information
Access important vehicle identification and calibration data.
- Select "Vehicle Information" from the app menu.
- View details such as Vehicle Identification Number (VIN), Calibration Identification (CAL ID), and Calibration Verification Numbers (CVN).
5.3. Battery Voltage Reading
Monitor your vehicle's battery voltage in real-time.
- Navigate to the "Battery Voltage Reading" section in the app.
- The app will display the current battery voltage, helping you assess its health.

5.4. Monitored Test and Freeze Frame Data Stream
These functions provide detailed insights into vehicle performance and fault conditions.
- Monitored Test: Allows you to check the status of various vehicle monitors (e.g., Misfire, Fuel System, O2 Sensor) since DTCs were last cleared.
- Freeze Frame: Captures a snapshot of engine conditions (parameters like engine RPM, coolant temperature, fuel pressure) at the exact moment a fault code is set. This data is crucial for diagnosing intermittent issues.
- Data Stream: Displays real-time sensor data from the vehicle, allowing for live monitoring of various parameters.

5.5. Performance Test
Evaluate your vehicle's acceleration and braking performance.
- Select "Performance Test" in the app.
- Follow the on-screen instructions to perform tests such as 0-100 km/h acceleration, braking distance from a certain speed, and distance testing (e.g., time to travel 500 meters).

7. Troubleshooting
If you encounter issues while using the V020 Car Scanner, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Loose connection to OBD2 port; Vehicle ignition not on; Vehicle battery low. | Ensure the scanner is firmly plugged into the OBD2 port. Turn the vehicle ignition to the "ON" position. Check vehicle battery voltage. |
| App cannot connect to the scanner. | Bluetooth not enabled on mobile device; Scanner not powered on; App not updated; Interference. | Enable Bluetooth on your mobile device. Ensure the scanner is powered on (connected to OBD2 port). Update the app to the latest version. Move away from strong electromagnetic interference sources. |
| Cannot read fault codes. | Vehicle ignition off; OBD2 port issue; Vehicle not OBD2 compliant. | Ensure vehicle ignition is in the "ON" position. Check the OBD2 port for damage. Verify your vehicle is OBD2 compliant (most vehicles manufactured after 1996 in the US are). |
| Codes clear but MIL comes back on. | Underlying vehicle issue not resolved. | Clearing codes only resets the light. The underlying problem must be diagnosed and repaired for the MIL to stay off. |
