⚠️ Note: Using non‑official drivers may permanently lock the ACTIA interface (fuse blow in Cypress FX2LP or STM32 MCU inside).

Always uninstall old drivers before switching between different ACTIA drivers. Use a dedicated, clean laptop for diagnostics to avoid conflicts with other USB devices.

Actia PSA Interface Driver: Technical Overview & Deployment The Actia PSA Interface Driver is the software bridge that enables communication between a PC and the PSA XS Evolution (or newer Core XS) Vehicle Communication Interface (VCI). This system is the standard diagnostic backbone for Peugeot, Citroën, DS, and Vauxhall/Opel vehicles using the DiagBox software suite. 1. Core Functionality

The driver serves several critical purposes in a professional or advanced hobbyist automotive environment:

Hardware Recognition: Allows Windows to identify the VCI (typically via USB) as a "PSA Interface" or "USB Com Board Driver".

Diagnostics & Repair: Facilitates tasks such as reading/clearing fault codes (DTCs), displaying real-time live data, and resetting service intervals.

Vehicle Configuration: Enables advanced operations including key programming, "telecoding" (reconfiguring ECU parameters), and actuator testing. 2. Official Software & Versions

Actia provides specific driver versions depending on the hardware model and operating system: PSA Interface Checker and Lexia Version - French Car Forum actia psa interface driver

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 If the driver is missing or outdated, your software will return errors like "Communication Initialization Failed" or "Interface Not Connected." 2.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 | Project | Description | | ---------------------- |

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

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. compatible with Windows 8

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 driver for the Actia PSA Interface (often referred to as the XS Evolution VCI) is typically bundled with diagnostic software like

. These drivers enable a Windows computer to communicate with the vehicle's electronic control units (ECUs) via a USB connection to the Actia hardware. 1. Driver Types and Versions

Depending on your specific hardware model and operating system, you may need one of the following drivers from the ACTIA IME Support Page Basic+ XS / CAT Level X Driver
