1. Introduction
The V119 OBD2 Scanner is a versatile diagnostic tool designed for EOBD/CAN compliant vehicles. It allows users to read and clear diagnostic trouble codes (DTCs), perform I/M readiness tests, monitor live data streams, and conduct battery voltage tests. This manual provides detailed instructions for setting up and operating your V119 scanner.
2. Product Features

- User-Friendly Interface: Intuitive navigation with Green/Yellow/Red visual indicators for quick status assessment.
- Multi-language Support: Supports 13 different languages.
- USB-Powered: Draws power directly from the vehicle's OBD2 port.
3. Setup and Connection
- Locate the OBD2 Port: The 16-pin OBD2 Data Link Connector (DLC) is usually located under the dashboard on the driver's side. Refer to your vehicle's service manual if you cannot find it.
- Turn Off Ignition: Ensure the vehicle's ignition is in the OFF position before connecting the scanner.
- Connect the Scanner: Plug the V119 scanner's OBD2 connector firmly into the vehicle's DLC.
- Turn On Ignition: Turn the vehicle's ignition to the ON position (engine off). The scanner will automatically power on and initiate communication with the vehicle's ECU.
- Language Selection (if needed): If prompted, select your preferred language using the navigation buttons.
4. Operating Instructions
4.1 Navigation
Use the OK button to confirm selections, EXIT to go back, and the directional arrows (Up, Down, Left, Right) to navigate through menus and options.
4.2 Diagnostic Menu Options
From the main 'Diagnostic Menu', you can select the following functions:
- Read Codes: Displays current, pending, and permanent Diagnostic Trouble Codes (DTCs).
- Erase Codes: Clears all DTCs from the vehicle's computer and turns off the Check Engine Light. Note: This does not fix the underlying problem.
- View Freeze Frame: Shows engine conditions (fuel trim, engine coolant temp, etc.) at the time the fault code was set.
- I/M Readiness: Checks the status of various emission-related monitors to determine if the vehicle is ready for an emissions test.
- Vehicle Info: Retrieves vehicle identification number (VIN), calibration ID (CALID), and calibration verification number (CVN).
- Data Stream: Displays live sensor data in numerical or graphical format.
4.3 Battery Test
The V119 scanner can perform a basic battery voltage test. Navigate to the 'Battery Test' option in the menu.
The scanner will display the current battery voltage and provide an assessment (e.g., Poor, Medium, Good) based on the voltage reading. This helps in quickly identifying potential battery issues.
4.4 Visual Indicators
The scanner features intuitive Green, Yellow, and Red LED indicators to provide a quick overview of the vehicle's status:
- Green: Indicates good condition, all monitors are running and passed.
- Yellow: Suggests attention is needed, some monitors may not be ready or a pending code exists.
- Red: Indicates a serious issue, a confirmed Diagnostic Trouble Code (DTC) is present, requiring immediate action.
5. Maintenance
- Cleaning: Use a soft, damp cloth to clean the scanner's exterior. Do not use abrasive cleaners or solvents.
- Storage: Store the scanner in a dry, cool environment, away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending or twisting the OBD2 cable excessively to prevent internal damage.
- Software Updates: Check the manufacturer's website periodically for any available software updates to ensure optimal performance and compatibility with newer vehicles.
6. Troubleshooting
- Scanner Does Not Power On:
- Ensure the OBD2 connector is securely plugged into the vehicle's DLC.
- Verify the vehicle's ignition is in the ON position.
- Check the vehicle's fuse for the OBD2 port (consult your vehicle's manual).
- Link Error/Communication Failure:
- Confirm the vehicle is OBD2 compliant (most vehicles from 1996 onwards in the US, 2001 in Europe for petrol, 2004 for diesel).
- Ensure the ignition is ON and the engine is OFF.
- Try connecting to a different OBD2 compliant vehicle to rule out scanner malfunction.
- Check for bent pins in the OBD2 connector on both the scanner and the vehicle.
- Incorrect Code Readings:
- Ensure the vehicle information (VIN, year, make, model) is correctly entered if prompted.
- Verify the scanner's software is up to date.
- DTCs Cannot Be Cleared:
- If the underlying fault that triggered the code is still present, the code will reappear immediately after clearing. Address the vehicle issue first.
- Some permanent codes may require multiple drive cycles to clear after the fault is resolved.

9. User Tips
- Always Consult Vehicle Manual: Before performing any diagnostics, it's advisable to consult your vehicle's owner's manual for specific information regarding its OBD2 system.
- Engine Off, Ignition On: Remember to have the engine off but the ignition on when connecting and operating the scanner for most functions.
- Record Codes: Always write down any Diagnostic Trouble Codes (DTCs) before clearing them. This can be helpful for future reference or if the problem persists.
- Understand I/M Readiness: If your vehicle fails an I/M Readiness test, it means some emission monitors have not completed their self-tests. This often requires driving the vehicle under specific conditions (drive cycle) to complete the tests.
- Clear Codes After Repair: Only clear codes after you have addressed the underlying issue. Clearing codes without fixing the problem will only result in the Check Engine Light returning.
