Setup and Connection
The Rodedio R009 OBD2 Scanner is designed for easy plug-and-play operation. Follow these simple steps to connect the device to your vehicle:
- Locate the OBD-II Port: The OBD-II port is usually located under the dashboard on the driver's side of the vehicle. Refer to your vehicle's owner's manual if you cannot find it.
- Connect the Scanner: With the vehicle's ignition off, firmly insert the Rodedio R009's OBD-II connector into your vehicle's OBD-II port.
- Turn on Ignition: Turn the vehicle's ignition to the "ON" position (do not start the engine). The scanner will power on automatically.
- Verify Connection: The scanner's screen will display a connection status. A successful connection will typically show a green checkmark or "Connected." If the connection fails, an exclamation mark or "Connection Error" may appear. Ensure the connector is securely seated and try again.

Operating Instructions
Once connected, navigate the scanner's menu using the F1, F2, EXIT, OK, and arrow buttons.
Main Menu Functions:
- Read DTC: Reads current, pending, and permanent Diagnostic Trouble Codes.
- Clear DTC: Clears all stored DTCs and turns off the Check Engine Light (CEL). Note: Clearing DTCs does not fix the underlying problem.
- Freeze Frame: Displays a snapshot of vehicle operating conditions at the time an emission-related fault occurred.
- I/M: Checks the readiness of the emission monitoring systems.
- Vehicle Info: Retrieves vehicle identification number (VIN), calibration ID (CALID), and calibration verification number (CVN).
- Live Data: Displays real-time data stream from the vehicle's sensors.
- Mode 6: Accesses results for on-board diagnostic monitoring tests of specific components/systems that are not continuously monitored.
- O2 Sensor: Retrieves O2 sensor monitoring test results.
- Mode 8: Performs control of on-board system, test, or component.
Using DTC Lookup:
When a DTC is displayed, you can use the built-in DTC library to get a detailed definition:
- Select "DTC Lookup" from the menu or press the appropriate button if available.
- Enter the DTC code (e.g., P0113).
- The scanner will display the definition, such as "Intake Air Temperature Sensor/Circuit High."

Viewing Live Data:
The Live Data Stream function allows you to monitor various sensor readings in real-time, which can be crucial for diagnosing intermittent problems.
- Select "Live Data" from the main menu.
- Choose the parameters you wish to monitor (e.g., Engine RPM, Intake Air Temperature, Ignition Timing Advance).
- The data will be displayed numerically and often graphically, showing minimum and maximum values over time.

Troubleshooting
- Scanner does not power on:
- Ensure the OBD-II connector is firmly plugged into the vehicle's port.
- Verify the vehicle's ignition is in the "ON" position.
- Check the vehicle's fuse for the OBD-II port (consult your vehicle's manual).
- "Connection Error" message:
- Unplug and re-plug the connector securely.
- Ensure the vehicle is OBD-II compliant (most vehicles manufactured after 1996 are).
- Try the scanner on another OBD-II compliant vehicle to rule out a scanner issue.
- Cannot clear DTCs:
- Ensure the ignition is "ON" and the engine is off.
- If the underlying fault is still present, the DTCs may reappear immediately after clearing. Address the vehicle issue first.
Maintenance
- Cleaning: Wipe the scanner with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending or crimping the OBD-II cable excessively to prevent damage.
User Tips
- Language Settings: The device supports multiple languages. If you need to change the language (e.g., to Russian or Turkish), navigate to the 'Setup' or 'Settings' menu on the device and select your preferred language.
