VCI (Diagnostic Unit) Serial Port (COM6) Driver

The VCI (Diagnostic Unit) Serial Port (COM6) driver allows Windows to communicate with an Autocom diagnostic interface over USB through a virtual serial port. It is intended for technicians and vehicle owners who need their diagnostic software to recognize the connected VCI, particularly after setting up a computer or reinstalling Windows.

Key Features

• USB-to-serial communication: Provides the serial-port connection used by compatible diagnostic software to communicate with the Autocom VCI.
• Device recognition: Helps Windows identify the diagnostic interface rather than leaving it listed as an unknown device or a device with a missing driver.
• COM port access: Makes the interface available through a Windows COM port. Although this device is labeled COM6, Windows may assign a different number depending on your setup.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your Windows version and architecture.

How to Install VCI (Diagnostic Unit) Serial Port (COM6) Driver

1. Check your system and interface. Confirm your Windows version, whether it is 32-bit or 64-bit, and your Autocom VCI model. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility requires separate verification.
2. Choose a compatible package. Before starting the VCI (Diagnostic Unit) Serial Port (COM6) driver download for Windows, review the package details. Look for the latest version compatible with your interface rather than assuming the newest release supports every model. If offered as a free download, verify its source and compatibility before proceeding.
3. Install the driver. Extract the downloaded archive if necessary and follow the included instructions. Run the installer if provided, or use Device Manager’s “Update driver” option to browse to the extracted driver folder. Connect the VCI when instructed.
4. Verify the connection. Open Device Manager and check “Ports (COM & LPT).” Confirm that the interface appears without a warning symbol and note its assigned COM number.
5. Configure your diagnostic application. Select the matching interface and COM port where required. If detection fails, check the USB connection and the application’s hardware compatibility requirements.

Keep a working driver updated when a compatible release addresses connection problems or supports your Windows configuration. Before you update, review the release notes and retain the previous installer so you can restore a known-working setup if needed.
