- Locate the OBD2 Port: The Diagnostic Link Connector (DLC) is typically located under the dashboard on the driver's side. Refer to your vehicle's manual if you cannot find it.
- Connect the Scanner: Plug the V350's OBD2 connector cable firmly into your vehicle's DLC.
- Turn on Vehicle Ignition: Turn your vehicle's ignition to the 'ON' position (engine off). The scanner will power on automatically.
- Vehicle Identification: The scanner will automatically scan and identify your vehicle's model.
- Access Diagnostic Menu: Once connected and powered, the main diagnostic menu will appear on the screen.
5. Operation
This section details the various functions and how to use them.
5.1. Basic Navigation
Use the Up and Down buttons to scroll through menu options. Press the OK button to select an option. Use the EXIT button to return to the previous screen.
5.2. Reading Diagnostic Trouble Codes (DTCs)
This function allows you to retrieve stored, pending, and permanent codes from the vehicle's computer.
- From the main menu, select 'Read Codes' and press OK.
- The scanner will display any detected DTCs.
- Use the Up/Down buttons to scroll through multiple codes if present.
5.3. Erasing Diagnostic Trouble Codes (DTCs)
Clearing DTCs will turn off the Check Engine Light (MIL) and erase all diagnostic data. Ensure the underlying issue is resolved before clearing codes.

- The scanner will display a list of available data parameters.
- Use Up/Down to scroll and OK to select specific parameters for detailed viewing.
5.6. View Freeze Frame Data
When an emission-related fault occurs, the vehicle's computer records a snapshot of operating conditions. This is called Freeze Frame Data.
- From the main menu, select 'View Freeze Frame' and press OK.
- The scanner will display the recorded parameters at the time the fault occurred.
5.7. DTC Lookup
This feature allows you to look up the definition of a DTC directly on the device.

6. Troubleshooting
If you encounter issues while using the OnRetul V350, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | Loose connection to OBD2 port; Vehicle ignition not on; Vehicle not OBD2 compliant. | Ensure the cable is securely connected. Turn the ignition to the 'ON' position. Verify your vehicle is OBD2 compliant. |
| Error message 'LINKING ERROR'. | Communication failure with vehicle. | Check the OBD2 cable connection. Ensure the ignition is on. Try connecting to a different OBD2 compliant vehicle if possible to rule out scanner issue. |
| Cannot clear codes. | Engine is running; Underlying fault still present. | Ensure the engine is off and the ignition is in the 'ON' position. The codes cannot be cleared if the fault is still active. Repair the issue first. |
| Inaccurate readings. | Faulty sensor in vehicle; Scanner software issue. | Compare readings with other diagnostic tools if available. Ensure the scanner's software is up to date (if applicable). |
