4. Setup and Initial Use

Follow these steps to set up your RODEDIO V519 OBD2 Scanner and begin diagnostics:

1. Locate the OBDII Port: The 16-pin OBDII Data Link Connector (DLC) is usually located under the dashboard on the driver's side of the vehicle. Refer to your vehicle's service manual for the exact location if needed.
2. Connect the Scanner: With the vehicle's ignition off, firmly plug the scanner's OBDII connector into the vehicle's DLC.
3. Turn On Ignition: Turn the vehicle's ignition to the 'ON' position (do not start the engine). The scanner will automatically power on and establish communication with the vehicle.
4. Verify Connection: The scanner's screen will display a connection status. A green indicator typically signifies a successful connection. If the connection fails (yellow or red indicator), ensure the cable is securely connected and the ignition is on.

5. Operating the Scanner

The RODEDIO V519 offers a range of diagnostic functions accessible through its main menu. Use the navigation buttons to scroll through options and the OK button to select.

Overview of the various OBDII functions available on the RODEDIO V519 scanner, including Read Codes, Erase Codes, Live Data, I/M Readiness, Freeze Frame, O2 Sensor Test, On-board Monitor Test, Vehicle Information, and Evap System.

5.1. Full OBD2 Modes

The scanner supports all 10 OBD2 diagnostic modes:

• Read Codes: Retrieves Diagnostic Trouble Codes (DTCs) from the vehicle's computer. These codes indicate specific issues detected by the system.

• O2 Sensor Test: Retrieves oxygen sensor monitor test results for the most recently completed tests from the vehicle's on-board computer.
• On-board Monitor Test: Retrieves test results for emission-related powertrain components and systems that are not continuously monitored.
• Vehicle Information: Retrieves the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN) of the vehicle.
• Evap System Test: Initiates a test of the Evaporative Emission Control System (EVAP) for leaks.

5.2. Engine Fault Diagnosis

The scanner can quickly read and clear engine fault codes, helping to diagnose and turn off the engine failure light.
