Actia Psa Interface Driver ✓

In Device Manager, you should see:

There are many clones and variations on the market. Driver compatibility depends entirely on your hardware revision.

Pro Tip: Always verify your interface by opening Device Manager before installing drivers. Note the USB Vendor ID (VID) and Product ID (PID). A genuine Actia typically shows VID_03F7 or VID_0525. Many clones use VID_0483 (STMicroelectronics).

Even with the correct driver, problems arise. Here are the top 5 issues and fixes.

The Actia PSA XS Evolution interface is the professional diagnostic tool used for Peugeot and Citroën vehicles, typically paired with DiagBox software. Getting the drivers to work correctly is the most common hurdle for DIY users. Driver Installation & Setup

For the interface to be recognized, you must use the specific ACTIAPnPInstaller (often version V3.1).

Operating System: For maximum stability, DiagBox (versions 7.x) should be installed on a 32-bit system, such as Windows 7 Pro or Windows XP SP3. Newer versions may support 64-bit, but driver conflicts are frequent.

Interface Checker: This utility is used to verify if the computer sees the hardware. If the checker does not recognize the interface, the software will not communicate with the car.

Firmware Updates: The interface may need a firmware flash (using the PSA Interface Checker) to be compatible with newer versions of DiagBox. Identifying Genuine vs. Clone Interfaces

Many drivers and software versions fail because the interface is a "clone" (replica) rather than an original Actia unit.

Physical Labels: Original units for Citroën typically feature numbers like 921815C or 922173A, while clones often share a generic number such as 921815B / 40W07 / 0005451.

"Made in France" Tag: Counter-intuitively, newer original units often do not say "Made in France," whereas clones frequently include this text on their silver nameplates. actia psa interface driver

Connectors: Original interfaces usually have a 6-digit white marking on the round black connector (e.g., "SD1505") and longer cables compared to replicas. Common Troubleshooting

Driver Conflicts: Installing multiple VCI (Vehicle Communication Interface) drivers on one laptop can cause communication errors.

Virtual Machines: If using a modern 64-bit OS, many users run the drivers and DiagBox within a Virtual Machine (VM) running Windows 7 32-bit to avoid compatibility issues.

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

The driver facilitates communication between your PC's USB port and the VCI hardware. Key identified drivers often seen in Device Manager include:

USB Com Board Evolution Driver (Multi-instance/UMDF): The primary driver for the XS Evolution interface.

USB PassThru Driver: Required for using the device as a universal J2534 adapter. Installation Guide

Instead of just saying "good product," this review addresses the three main pain points users search for:

Finding and installing the correct ACTIA PSA interface driver is the most common hurdle for technicians setting up Peugeot and Citroën diagnostic systems like Diagbox, Lexia 3, or PP2000. Whether you are using an original ACTIA Evolution XS unit or a high-quality revision C clone, the driver acts as the bridge between your Windows OS and the vehicle’s ECU.

Here is a comprehensive guide on how to identify, install, and troubleshoot the ACTIA PSA interface driver. 1. Understanding the ACTIA PSA Interface

The ACTIA interface (often referred to as the Lexia 3 interface) utilizes a specific USB-to-serial communication protocol. Because these diagnostic tools often rely on legacy software, the driver must be perfectly matched to both your hardware "revision" and your version of Windows. In Device Manager, you should see:

Most modern setups require the USB Com Board Driver (Multi-Instance). 2. Preparing Your System

Before installing the driver, ensure your environment is ready:

Operating System: While Diagbox can run on Windows 10 or 11 (usually via 32-bit compatibility or Virtual Machines), the drivers are most stable on Windows 7 32-bit.

Disable Antivirus: Diagnostic software is often flagged as "false positive" malware. Disable your firewall and antivirus during the driver installation.

Disconnect Internet: To prevent Windows Update from automatically installing a generic (and often non-functional) driver, stay offline. 3. Step-by-Step Driver Installation

If you have a Diagbox installation package, the drivers are usually located in a folder named Drivers or ACTIA_Drivers.

Plug in the Interface: Connect the ACTIA unit to your PC via USB. (Do not connect it to the car yet).

Open Device Manager: Right-click 'This PC' > Manage > Device Manager.

Identify the Device: Look for an "Unknown Device" or "ACTIA USB Devices." It may appear as "USB Com Board Driver". Update Driver: Right-click the device and select Update Driver Software. Choose "Browse my computer for driver software." Point the search to your driver folder.

Verification: Once installed, the device should appear under "ACTIA USB Devices" as "USB Com Board Evolution Driver (Multi-instance)." 4. The "Revision C" Factor

Many users struggle because their interface is "Revision B," while newer versions of Diagbox (v7.xx and v9.xx) require Revision C. There are many clones and variations on the market

If your driver is installed correctly but the software says "Interface not connected," you likely need to flash your interface firmware.

Use a tool called PSA Interface Checker to see your current version. If it lists "Reference 921815 C/," your drivers and hardware are compatible with the latest software. 5. Troubleshooting Common Issues "Device Not Recognized"

This usually happens if the USB cable is faulty or the soldering inside the ACTIA unit has cracked. Try a shorter USB lead, as the ACTIA interface is sensitive to voltage drops. "Code 10" or "Code 43" Error in Device Manager

This indicates a driver mismatch. Uninstall the current driver, restart the PC, and manually select the driver from the C:\AWRoot\bin\fi\Drivers directory (if Diagbox is already installed). Driver Signature Enforcement

On Windows 10 and 11, the driver may fail because it isn't digitally signed.

The Fix: Restart Windows in "Disable Driver Signature Enforcement" mode (via Advanced Startup options) to allow the ACTIA files to initialize. Conclusion

The ACTIA PSA interface driver is the backbone of your Citroën/Peugeot garage setup. By ensuring you are using the Multi-Instance driver on a 32-bit architecture, you can avoid 90% of the connection errors that plague DIY mechanics. To help you get the right setup, could you tell me: Which version of Windows are you using? What is the Diagbox version you're trying to run?

I can then provide the specific driver files or compatibility settings you'll need.

The Actia PSA XSight (or older "Pass-Thru" VCI) is the OEM-level diagnostic interface for PSA Group vehicles. It connects your Windows laptop to the vehicle’s OBD2 port to run dealer-level software (DiagBox, Lexia, PP2000).

Unlike generic ELM327 interfaces, the Actia unit requires proper signed drivers to work with PSA software in "Vehicle Communication Interface (VCI)" mode.

The Actia PSA interface driver is a critical bridge enabling safe, reliable diagnostic and programming operations on PSA vehicles using Actia hardware. It implements vehicle and hardware-specific transport, timing, security, and session rules so diagnostic applications can operate at a higher level without handling low-level protocol intricacies. Correct implementation and use ensure successful diagnostics, safe ECU reprogramming, and a dependable workshop workflow.
