4. Setup and Installation
- Locate the OBD2 Port: The OBD2 port is typically located under the dashboard on the driver's side of the vehicle. Refer to the diagram below for common locations.
- Connect the Scanner: With the vehicle's ignition turned off, firmly plug the V100 OBD2 Code Reader's 16-pin connector into your vehicle's OBD2 port.
- Power On: Turn the vehicle's ignition key to the "ON" position (do not start the engine). The V100 scanner will automatically power on, drawing power from the vehicle's battery.
- Start Diagnosis: The device is now ready for use. Follow the on-screen instructions to navigate the diagnostic menu.
This diagram illustrates typical locations for the OBD2 diagnostic port within a vehicle's interior.

- Area B: Honda, Volkswagen Terament, imported Lexus, and other models.
- Area C: Dongfeng Citroen, Dongfeng Peugeot, and a small number of other vehicles.
- Area D: Dongfeng Citroen and a small number of other vehicles.
- Area E: Other few vehicles.
5. Operating Instructions
Once connected and powered on, the V100 will display the main diagnostic menu. Use the navigation buttons (Up/Down arrows, OK, EXIT, DTC) to select and perform various diagnostic functions.
The main screen of the V100, displaying options such as Read Codes, Erase Codes, View Freeze Frame, and I/M Readiness.
5.1. Main Menu Options
- Read Codes: Select this option to retrieve Diagnostic Trouble Codes (DTCs) stored in the vehicle's Engine Control Unit (ECU). The device will display the code and its definition.
- Erase Codes: After addressing a fault, select this option to clear the DTCs from the ECU and turn off the Check Engine Light (MIL). Ensure the ignition is on but the engine is off before erasing codes.
- View Freeze Frame: This function displays a snapshot of sensor data recorded by the ECU when an emission-related fault occurred. This data can help in diagnosing the cause of the fault.
- I/M Readiness: Checks the status of the vehicle's emission-related monitoring systems to determine if they are ready for an inspection/maintenance test.
- Vehicle Information: Displays information such as Vehicle Identification Number (VIN), Calibration ID (CIN), and Calibration Verification Number (CVN).

5.2. DTC Definition Lookup
When a Diagnostic Trouble Code (DTC) is displayed, the V100 provides a direct definition on the screen, eliminating the need to search online. This feature helps in quickly understanding the nature of the fault.
