4. Setup
4.1 System Requirements
- Operating System: Windows XP or Windows 7 (32-bit recommended).
- USB Port: Available USB 2.0 or 3.0 port.
- Disk Space: Sufficient space for software installation.
Important: Temporarily disable your anti-virus program during software installation to prevent interference.
4.2 Software Installation

- Follow the on-screen instructions to install the VAUX-COM software and necessary drivers.
- If the CD is unreadable or damaged, please contact the seller for a download link to the software and drivers.
4.3 Hardware Connection
- Connect one end of the USB cable to your computer and the other end to the OPCOM diagnostic interface.
- Locate your vehicle's OBD2 diagnostic port, typically found under the dashboard on the driver's side.
- Connect the 16-pin connector of the OPCOM diagnostic interface to the vehicle's OBD2 port.
- For older Opel models that use a 10-pin connector, use the optional 10-pin to 16-pin adapter cable (if applicable) to connect the interface to the vehicle.
5. Operation
5.1 Starting the Software and Interface Test
- Turn the vehicle's ignition to the 'ON' position (do not start the engine unless required by a specific test).
- Launch the VAUX-COM software on your computer.
- The software may automatically perform an interface test. Ensure you see a message indicating "Interface test ended successfully."
5.2 Vehicle Identification
From the main menu, select 'Diagnostics'. You can choose to identify the vehicle automatically or manually by selecting the year and model from the provided lists.
5.3 Main Diagnostic Functions
The VAUX-COM software supports various control units including Engine, Automatic Transmission, ABS, Airbag, Engine Cooling module, Instrument Cluster, Electronic Climate Control, and Body Control Unit.
-
Read and Clear Fault Codes: The program allows you to read out and clear diagnostic trouble codes (DTCs). Fault codes are displayed with full status information (Present, Not present, Intermittent). You can print, save, or copy these codes to other applications.
Figure 10: Fault codes display in VAUX-COM. -
Live Data (Measuring Blocks): View real-time data from various sensors and components. The program can display up to 8 measuring block parameters simultaneously. The sample rate varies depending on the communication protocol (e.g., older ISO-9141-2 systems are slower than newer KWP-2000 or CAN-BUS units).

5.4 Communication Protocols
The diagnostic interface acts as a multiplexer, selecting the appropriate pins for communication:
- PIN3, PIN7, PIN8, PIN12 = Serial Link (ISO9141, KW81, KW82, KWP2000)
- HSCAN - Dual-wire, High Speed CAN-BUS, 500 kbps
- MSCAN - Dual-wire, Medium Speed CAN-BUS, 95 kbps
- SWCAN - Single-wire, Low Speed CAN-BUS, 33.3 kbps
6. Maintenance
- Keep the diagnostic tool clean and dry. Use a soft, dry cloth for cleaning.
- Store the device in a safe place, away from dust and moisture, when not in use.
- Regularly check for software updates to ensure compatibility with the latest vehicle models and improved functionality.
- Inspect the USB cable and diagnostic connector for any signs of damage before each use.
7. Troubleshooting
- Software CD Unreadable/Damaged: If you receive a damaged or unreadable software CD, please contact the seller directly to request a download link for the software and drivers.
- Software Not Launching/Working: Ensure your anti-virus program is temporarily disabled during installation and initial setup, especially on Windows XP and 7 (32-bit) systems, as it may interfere with the software or driver installation.
-
Connection Issues:
- Verify that the USB cable is securely connected to both the computer and the diagnostic interface.
- Ensure the diagnostic interface is firmly plugged into the vehicle's OBD2 port.
- Check if the correct drivers are installed for the device. You can usually verify this in your computer's Device Manager.
-
No Communication with Vehicle:
- Confirm the vehicle's ignition is in the 'ON' position.
- Ensure the vehicle model and year selected in the software match your vehicle.
- For older vehicles, ensure the 10-pin to 16-pin adapter is correctly used if required.
