Before using the OnRetul V315, ensure your vehicle is OBD2 compliant. This tool is compatible with gasoline cars produced after 1996 (USA), 2002 (EU), and 2008 (Asia). It does not support hybrid, electric, or non-OBD2 models. This product does not support ABS, SRS, or TPMS detection.
Connecting the Device
- Locate your vehicle's 16-pin OBD2 diagnostic port. This port is typically found under the dashboard on the driver's side.
- Ensure the vehicle's ignition is in the OFF position.
- Firmly plug the V315's OBD2 connector into the vehicle's diagnostic port.
- Turn the vehicle's ignition to the ON position (do not start the engine). The V315 will power on automatically.

4. Operating Instructions
Once connected and powered on, the V315 will display the main menu. Use the directional buttons (Up, Down, Left, Right) and the OK button to navigate and select options.
4.1. Reading Diagnostic Trouble Codes (DTCs)
- From the main menu, select "Read Codes" and press OK.
- The tool will scan the vehicle's systems for stored DTCs.
- Any detected codes will be displayed along with their descriptions.
4.2. Clearing Diagnostic Trouble Codes (DTCs)
Clearing DTCs will turn off the Check Engine Light (MIL). Ensure you have addressed the underlying issue before clearing codes, as they may reappear if the problem persists.
- From the main menu, select "Erase Codes" and press OK.
- Confirm the action when prompted.
- The Check Engine Light should turn off, and stored DTCs will be cleared from the vehicle's computer.

4.3. I/M Readiness Check
The I/M Readiness function checks the status of various emission-related monitors to determine if the vehicle is ready for an emission test.
- From the main menu, select "I/M Readiness" and press OK.
- The tool will display the status of the vehicle's monitors (e.g., MIL, MIS, FUE, CCM, CAT, EVAP, O2S, HRT, EGR). A green checkmark indicates the monitor is complete, while a red 'X' indicates it is incomplete.

4.4. Live Data Stream
View real-time operational parameters of the vehicle, such as engine RPM, vehicle speed, coolant temperature, and fuel pressure.
- From the main menu, select "Data Stream" and press OK.
- The tool will display various data parameters in real-time.
4.5. View Freeze Frame
When an emission-related fault occurs, the vehicle's computer stores a snapshot of operating conditions at that moment. This is called Freeze Frame Data.
- From the main menu, select "View Freeze Frame" and press OK.
- The tool will display the recorded parameters.
5. Maintenance
The OnRetul V315 is a low-maintenance device. Follow these guidelines to ensure its longevity:
- Keep the device clean and free from dust and moisture.
- Store the device in a dry, cool environment when not in use.
- Avoid dropping the device or subjecting it to strong impacts.
- Do not attempt to disassemble the device, as this will void the warranty.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Loose connection to OBD2 port; vehicle ignition not ON; vehicle not OBD2 compliant. | Ensure the connector is firmly seated. Turn vehicle ignition to ON. Verify vehicle compatibility. |
| Cannot link to vehicle. | Vehicle not OBD2 compliant; communication error; faulty OBD2 port. | Verify vehicle compatibility. Check for loose connections. Try on another OBD2 compliant vehicle if possible. |
| Codes cannot be cleared. | Underlying fault still present; ignition not ON. | Address the root cause of the DTCs first. Ensure ignition is ON. |
