The Actia PSA Interface, commonly known as the XS Evolution or Lexia 3, is a professional-grade diagnostic tool used to communicate with electronic control units (ECUs) in Peugeot, Citroën, DS, and recent Vauxhall vehicles. The "driver" refers to the software bridge that allows a Windows PC to recognize the hardware via USB to perform diagnostics, coding, and ECU reprogramming. 1. Hardware Overview
The interface is a Vehicle Communication Interface (VCI) that connects a vehicle's OBD-II port to a laptop.
Protocols Supported: K-Line, CAN-BUS, SAE J1850, and modern DoIP (Diagnostics over IP) for newer models. Key Models: XS Evolution: The legacy standard for DiagBox software.
PSA CORE XS: A newer, high-performance variant featuring 8GB flash memory and dual-stream WLAN for advanced diagnostics.
Original vs. Clone: Authentic units have unique serial numbers (e.g., starting with 921815C or 922173A). Clones often use generic serials like 921815B and may require manual firmware patches to work with newer software. 2. Driver Installation and Setup actia psa interface driver
Drivers are rarely installed as standalone files; they are typically bundled with diagnostic software suites.
Automatic Installation: Drivers for the VCI are usually installed automatically during the initial setup of DiagBox (Version 7 and later).
VCI Setup Utility: For modern systems like wiTECH (used for newer PSA/FCA crossovers), a specific VCI Setup Utility must be downloaded from the Mopar Technical Service Portal or Service Box to ensure the latest drivers are active.
Compatibility: Most drivers require Windows 7 (32-bit) for legacy stability, though newer versions support Windows 10/11 through specialized installers like the VCI Setup Utility. 3. Essential Management Tools
Two primary utilities are used to manage the interface driver and hardware:
PSA Interface Checker: A diagnostic tool for the interface itself. It allows users to check the current firmware version and manually "flash" or update the firmware if the driver fails to communicate with newer software versions. Would you like a quick reference checklist or

used for diagnosing Peugeot, Citroën, DS, and Vauxhall vehicles
. As the official diagnostic hardware partner for PSA Group, ACTIA provides the essential link required by software like to perform deep-level electronic maintenance. Core Functionality
The driver serves as a bridge, translating high-level diagnostic commands into the low-level serial or network protocols understood by a vehicle's Electronic Control Units (ECUs). Protocol Support: Compatible with modern standards including DoIP (Ethernet ISO 13400) Operations:
Once installed, it allows for reading and clearing fault codes (DTCs), viewing live sensor data (e.g., engine speed, battery voltage), ECU reprogramming, and actuator testing (e.g., fuel pump activation). Device Modes: Advanced drivers for tools like the PSA Evolution A Based on ACTIA SDK release notes (2024–2025):
allow the interface to switch between different modes, such as (standard dealership diagnostics) and (used for newer DS and Chrysler/Mopar platforms). Driver Installation & Configuration
Drivers are typically bundled with diagnostic software suites, but manual installation is common in independent repair settings. PSA Interface Checker and Lexia Version - French Car Forum
