4. Setup and Connection

Follow these steps to connect the OnRetul V100 scanner to your vehicle:

1. Locate the vehicle's 16-pin Data Link Connector (DLC). This is typically found under the dashboard on the driver's side.
2. Ensure the vehicle's ignition is OFF.
3. Plug the V100 scanner's OBD-II connector cable firmly into the vehicle's DLC.
4. Turn the vehicle's ignition to the ON position (engine off). The scanner will automatically power on and display the main menu.

If the scanner does not power on, check the connection to the DLC and ensure the vehicle's battery has sufficient charge.

5. Operating Instructions

The V100 scanner provides several diagnostic functions. Use the Up/Down arrow buttons to navigate through menu options and the OK button to select. The EXIT button returns to the previous screen.

5.1. Reading Diagnostic Trouble Codes (DTCs)

This function retrieves stored, pending, and permanent diagnostic trouble codes from the vehicle's engine control unit (ECU).

1. From the main menu, select "Read Codes" and press OK.
2. The scanner will display any detected DTCs. Use the Up/Down arrows to scroll through multiple codes.
3. Each code will include a description to help identify the issue.

5.2. Erasing Diagnostic Trouble Codes (DTCs)

This function clears all stored DTCs and turns off the Check Engine Light (MIL). Note: Clearing codes does not fix the underlying problem. The codes may reappear if the fault is not repaired.

1. From the main menu, select "Erase Codes" and press OK.
2. Confirm your selection when prompted.
3. The Check Engine Light should turn off, and all DTCs will be cleared from the ECU.

5.3. Viewing Live Data Stream

This function displays real-time operational parameters from the vehicle's sensors and components, such as engine RPM, vehicle speed, coolant temperature, fuel system status, and O2 sensor readings.

1. From the main menu, select "Live Data" and press OK.
2. The scanner will display a list of available data parameters.
3. Use the Up/Down arrows to scroll through the data. Some parameters may be displayed graphically.

5.4. I/M Readiness Test

I/M Readiness (Inspection/Maintenance Readiness) indicates whether the various emissions-related systems on the vehicle are operating correctly and have completed their self-tests. This is crucial for emission inspections.

1. From the main menu, select "I/M Readiness" and press OK.
2. The scanner will display the status of various monitors (e.g., Misfire Monitor, Fuel System Monitor, Comprehensive Component Monitor, O2 Sensor Monitor, EVAP System Monitor).
3. A "OK" or "Complete" status indicates the monitor has run and passed. "INC" or "Incomplete" means the monitor has not yet completed its test cycle.

5.5. Viewing Freeze Frame Data

When an emission-related fault occurs, the ECU stores a "freeze frame" of vehicle operating conditions at the moment the fault was detected. This data can help diagnose intermittent problems.

1. From the main menu, select "View Freeze Frame" and press OK.
2. The scanner will display parameters such as engine speed, vehicle speed, coolant temperature, and fuel pressure recorded at the time of the fault.

5.6. DTC Lookup

The V100 includes a built-in database of over 10,000 Diagnostic Trouble Codes, allowing you to quickly search for code definitions without needing an internet connection.

1. Press the dedicated "DTC" button on the scanner or select "DTC Lookup" from the menu.
2. Enter the DTC using the navigation buttons.
3. Press OK to view the definition of the code.

5.7. Battery & Alternator Check (Voltage Tester)

While not a dedicated battery tester, the V100 can display the vehicle's battery voltage through the OBD-II port, providing an indication of the battery's readiness and the alternator's output.

1. Access the "Live Data" menu.
2. Look for a parameter labeled "Battery Voltage" or "System Voltage."
3. A healthy battery typically shows around 12.6V when the engine is off and 13.5V-14.5V when the engine is running (alternator charging).

5.8. Other Functions

• O2 Sensor Test: Retrieves O2 sensor monitoring test results for the most recently completed tests from the vehicle's on-board computer.
• EVAP System Test: Initiates a leak test for the vehicle's Evaporative Emission Control System.
• Vehicle Info: Retrieves the Vehicle Identification Number (VIN), Calibration ID (CALID), and Calibration Verification Number (CVN) of the test vehicle.

6. Maintenance

Proper maintenance ensures the longevity and reliable operation of your OnRetul V100 scanner.

• Cleaning: Use a soft, damp cloth to clean the scanner's casing. Do not use abrasive cleaners or solvents.
• Storage: Store the scanner in a dry, cool environment, away from direct sunlight and extreme temperatures.
