Comprehensive Guide to Actia PSA XS Evolution (9780.Z5) Drivers
If you are a Peugeot or Citroën enthusiast, or a professional mechanic working with PSA Group vehicles, you’ve likely encountered the Actia PSA XS Evolution (9780.Z5) interface. This hardware is the backbone of dealer-level diagnostics, allowing you to use software like Lexia 3, PP2000, and Diagbox.
However, the hardware is only as good as the software communication. Getting the drivers installed correctly is often the biggest hurdle in setting up a functional diagnostic station. What is the Actia PSA XS Evolution 9780.Z5?
The 9780.Z5 refers to the specific hardware revision of the Actia communication interface. Unlike generic OBD-II scanners that only read basic engine codes, this interface provides:
Full ECU Identification: Reads and displays complete identification of the control units.
Fault Code Management: Reads, displays, and clears all diagnostic trouble codes (DTCs).
Auto-Scan: Detects all ECUs installed in the car and reads all diagnostic fault codes.
Live Data: Displays real-time parameters like engine speed, battery voltage, and oxygen sensor data.
Actuator Tests: Allows you to manually trigger components like fuel pumps, steering wheel locks, and injectors. Understanding Driver Compatibility Actia Psa Xs Evolution 9780.z5 Driver
The driver for the PSA XS Evolution is unique because it must act as a bridge between your PC’s USB port and the Diagbox/Lexia software environment. 1. Operating System Requirements
The biggest challenge with these drivers is Windows compatibility.
Windows XP (32-bit): The native environment for Lexia 3 and PP2000. Drivers install most easily here.
Windows 7 (32-bit): The "sweet spot" for Diagbox versions 7.xx.
Windows 10/11 (64-bit): Modern systems often struggle with these drivers. Most professionals use a Virtual Machine (VM) running Windows 7 32-bit to ensure the drivers initialize correctly. 2. The "USB Com Board Driver"
When you plug the device into your computer, it should appear in the Device Manager as "UMDF PSA-XS Evolution Plug-in" or "USB Com Board Driver (Multi-instance)." If it appears as an "Unknown Device," the software will fail to communicate with the vehicle. How to Install the Actia 9780.Z5 Driver Follow these steps to ensure a clean installation: Step 1: Disable Driver Signature Enforcement
If you are on Windows 10 or 11, the OS may block the driver because it isn't digitally signed by modern standards. You must restart your PC in "Disable Driver Signature Enforcement" mode before attempting the install. Step 2: Install Diagbox First
The driver is typically bundled with the Diagbox software installation. Run the Diagbox setup as an Administrator. Comprehensive Guide to Actia PSA XS Evolution (9780
Do not plug in the USB interface until the software specifically asks for it or until the installation is complete.

Right-click the device (often under "Other Devices" or "Universal Serial Bus controllers"). Select Update Driver > Browse my computer for drivers.
Navigate to the installation directory (usually C:\Diagbox\drivers or similar). Firmware vs. Driver: The Common Confusion
Sometimes the driver is installed correctly, but the software still says "Incompatible Interface." This is usually a firmware issue, not a driver issue.
The 9780.Z5 hardware requires specific firmware versions to work with newer versions of Diagbox (e.g., version 7.02 requires firmware 4.3.0). You may need a PSA Interface Checker tool to flash the hardware firmware to match your software version. Troubleshooting Tips
