The Actia PSA interface driver is a specialized software component that enables diagnostic communication between a vehicle’s electronic control units (ECUs) and diagnostic applications using Actia hardware tailored for PSA (Peugeot Société Anonyme — now part of Stellantis) vehicles. This narrative explains what the driver does, why it matters, how it works at a high level, typical features, and practical considerations for developers and technicians.
ACTIA driver provides internal logging (enabled via registry key on Windows):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ACTIA_PSA\Parameters
"LogLevel" = DWORD:0x3 (info+debug)
"LogFile" = "C:\ACTIA_Driver.log"
Log includes:
Run DiagBox → Select “Lexia” or “PP2000” → Global Test.
If the software communicates with the vehicle (VIN appears automatically), the driver is correctly installed.
✅ Pro tip: Always use a dedicated Windows 10 64-bit laptop with no other diagnostic software (to avoid USB driver conflicts). Disable automatic driver updates via Group Policy.
The ACTIA PSA Interface (often referred to as the XS Evolution or VCI) is the specialized hardware link used to connect Peugeot and Citroën vehicles to diagnostic software like DiagBox, Lexia 3, and PP2000. 1. Driver Installation & Availability
Automated Setup: Drivers for the ACTIA interface are typically bundled within the DiagBox software installer. They are installed during the initial setup (e.g., version 7.02) and should automatically recognize the device when plugged into a USB port.

Troubleshooting and Installing the Actia PSA Interface Driver for Lexia 3 & PP2000
If you are a Peugeot or Citroën owner into DIY diagnostics, you’ve likely encountered the Actia PSA interface. This hardware is the bridge between your car’s ECU and dealer-level software like Lexia 3, PP2000, or the newer Diagbox. However, the most common hurdle users face isn't the software itself—it's getting the Actia PSA interface driver to communicate correctly with Windows.
In this guide, we’ll walk through how to identify, install, and troubleshoot your drivers to ensure a stable connection every time you plug into your OBD2 port.
1. Understanding the Hardware: Evolution of the XS Evolution
The Actia PSA interface (often labeled as "XS Evolution") has several versions. The "Full Chip" versions are generally more stable and compatible with modern 64-bit operating systems.
When you plug the device into your USB port, Windows looks for a specific driver to categorize it as a "USB Com Board Driver (Multi-instance)". If the driver is missing or outdated, your software will return errors like "Communication Initialization Failed" or "Interface Not Connected." 2. Driver Compatibility: Windows 7 vs. Windows 10/11
The Actia interface was originally designed for Windows XP and Windows 7 32-bit. This is where most installation headaches begin.
32-bit (x86): Generally plug-and-play once Diagbox is installed.
64-bit (x64): Requires signed drivers or "Disable Driver Signature Enforcement" to be active during installation. Most modern versions of Diagbox (v7.83 and above) include a 64-bit driver patch, but manual intervention is often required. 3. How to Install the Actia PSA Interface Driver Step 1: Install the Main Software First
Do not plug in the interface yet. Install your diagnostic software (Diagbox is recommended as it contains the most up-to-date driver library). During the installation, the setup will typically prompt you to install the Actia drivers. Step 2: Connect the Interface
Connect the interface to your PC's USB port. You should hear the "hardware connected" chime. Step 3: Check Device Manager
Right-click 'This PC' or 'My Computer' and select Manage > Device Manager. Look for ACTIA USB Devices.
Under this, you should see USB Com Board Driver (Multi-instance).
If you see a yellow exclamation mark or "Unknown Device," right-click it, select Update Driver, and point the search to the C:\AWroot\bin\fi\INF directory (the default path for Diagbox drivers). 4. The "PSA Checker" Utility
If your driver is installed but the software still won't talk to the car, you need the PSA Interface Checker. This small utility identifies the firmware version of your Actia tool.
Reference "C": This is the gold standard. If your interface shows as Reference "B," it may require a firmware flash to work with newer versions of Diagbox.
Firmware Version: Ensure your firmware matches the version required by your software build (e.g., 4.3.0 or 4.3.7). 5. Common Troubleshooting Tips The Actia PSA interface driver is a specialized
USB 3.0 Ports: The Actia interface can be picky with USB 3.0 (blue) ports. If possible, use a USB 2.0 port or a non-powered USB 2.0 hub to stabilize the connection.
VMware Users: If running Diagbox on a Virtual Machine (common for Windows 10/11 users), ensure the USB controller is set to USB 2.0 in the VM settings and that the "Actia" device is "Connected" to the guest OS, not the host.
Cable Length: Avoid using long USB extension cables, as they can cause voltage drops that lead to driver timeouts. Conclusion
Getting the Actia PSA interface driver right is 90% of the battle when setting up Peugeot/Citroën diagnostics. By ensuring you have a "Full Chip" interface and verifying the "USB Com Board Driver" status in Device Manager, you'll save hours of frustration.
The Actia PSA Interface Driver is a foundational component for the Lexia 3 / XS Evolution vehicle communication interface (VCI), used to diagnose Peugeot and Citroën vehicles through Diagbox software. In most cases, these drivers are bundled with the software and install automatically when you first set up Diagbox. Core Function & Components
