Actia Psa Xs Evolution 9780z5 Driver May 2026

The ACTIA PSA XS Evolution interface, often identified by the part number 9780.Z5, is the gold standard for dealer-level diagnostics on Peugeot and Citroën vehicles. However, getting this hardware to talk to a modern PC requires the correct driver installation and firmware management. This guide covers everything you need to know about the 9780.Z5 driver and setup process. Understanding the 9780.Z5 Hardware

The ACTIA PSA XS Evolution is the communication bridge between your laptop and the vehicle's ECU. The 9780.Z5 designation specifically refers to the high-quality, evolution version of the interface.

Compatibility: Works with Lexia 3, PP2000, and DiagBox software. Connection: Uses a USB-to-OBD2 link.

Function: Enables global scans, fault code clearing, and ECU telecoding. Where to Find the Driver

The driver for the PSA XS Evolution is typically bundled within the DiagBox software installation. When you install DiagBox, the system automatically places the necessary USB drivers into the program files.

Driver Path: Usually found in C:\APP\Drivers or the DRIVERS folder within your installation directory.

Driver Name: In Device Manager, the interface should appear under Universal Serial Bus controllers as "ACTIA USB Devices" or "Evolution Driver." Step-by-Step Driver Installation

If your computer fails to recognize the interface, follow these steps to manually point the system to the correct driver:

Plug in the Interface: Connect the 9780.Z5 to your USB port.

Open Device Manager: Right-click the Start button and select Device Manager.

Locate the Device: Look for an "Unknown Device" or a device with a yellow exclamation mark under USB controllers.

Update Driver: Right-click the device and select "Update driver." Manual Search: Choose "Browse my computer for drivers." actia psa xs evolution 9780z5 driver

Set the Path: Navigate to your DiagBox installation folder (commonly C:\AWRoot\bin\fi\psa_diags_drivers). Confirm: Click OK and let Windows finish the installation. Common Issues and Solutions 1. 64-bit Windows Compatibility

The original Lexia 3 and PP2000 drivers were designed for 32-bit systems (Windows XP or Windows 7 32-bit). If you are using a 64-bit version of Windows 10 or 11, the drivers may not initialize properly.

Solution: Use a Virtual Machine (VM) running Windows 7 32-bit for the most stable connection. 2. Firmware Version Mismatch

Sometimes the driver is fine, but the firmware on the 9780.Z5 is outdated.

Solution: Use the "PSA Interface Checker" tool to verify your firmware version. For modern DiagBox versions (v7.xx or v9.xx), you generally need firmware version 4.3.0 or higher. 3. "Reference Serial" Identification

Lower-quality clones often struggle with newer drivers. A "Full Chip" 9780.Z5 interface is recognized by the driver as "Reference Serial C," which is necessary for DiagBox to function beyond version 5.02. Maintenance Tips

Avoid USB 3.0 Ports: These interfaces often prefer the older, slower USB 2.0 ports for stable data transmission.

Disable Antivirus: During driver installation, antivirus software can sometimes block the "Actia" .sys files.

Check the Cable: The short USB cable included with many 9780.Z5 kits is prone to failure; if the driver keeps disconnecting, try a high-quality replacement cable.

By ensuring your ACTIA PSA XS Evolution 9780.Z5 driver is correctly mapped and your firmware is up to date, you can unlock the full diagnostic potential of your Peugeot or Citroën vehicle, saving thousands in dealership fees.

Getting Started with the Actia PSA XS Evolution (9780.Z5) Driver The ACTIA PSA XS Evolution interface, often identified

If you’re a Peugeot or Citroën owner, you know that the Actia PSA XS Evolution (9780.Z5) is the gold standard for DIY diagnostics. However, getting the driver and software—typically DiagBox, Lexia 3, or PP2000—to play nice with modern versions of Windows can be a challenge.

Here is a guide to finding and installing the correct drivers for your interface. 1. Where to Find the Driver

Drivers for the Actia XS Evolution are typically bundled with the diagnostic software rather than distributed as standalone files.

Official Support: For professional users, drivers can sometimes be found on the ACTIA IME Support page, which lists Level X drivers for the XS Family.

Software Bundles: Most users get their drivers through DiagBox. Modern "Native" versions like DiagBox 9.85 or 9.150 include integrated VCI (Vehicle Communication Interface) drivers that support Windows 10 and 11.

Third-Party Repositories: Sites like DriverScape host archives, but use caution and ensure you match your specific hardware ID. 2. Compatibility & Windows Versions

The 9780.Z5 interface is older hardware, so your operating system matters:

Windows XP / 7 (32-bit): The most stable "native" environment for older Lexia 3 and PP2000 software.

Windows 10 / 11: Requires newer versions of DiagBox (V9.xx). Many enthusiasts prefer using a Virtual Machine (VM) pre-loaded with the software and drivers to avoid registry conflicts on their main OS. 3. Installation Steps To ensure your computer recognizes the interface:

Install the Software First: Always install DiagBox before plugging in the USB cable. The installation process usually places the necessary driver files in a temporary folder or system directory.

Connect the VCI: Plug the XS Evolution into your USB port. Windows should attempt to "Search for Drivers." The Interface: ACTIA XS Evolution (Blue or Black

Manual Update: If it fails, open Device Manager, find the "ACTIA USB Devices" or "Unknown Device," and manually point it to the installation folder of your software (typically C:\AWRoot or similar).

Verify with Interface Checker: Use a utility called PSA Interface Checker to confirm the firmware version. For most DiagBox versions, your firmware should be around 4.2.4 or higher to be recognized. 4. Important Troubleshooting Tips

"Device Not Recognized": Try a different USB cable (specifically the shorter one if your kit came with two) or a different USB port.

Driver Type: Some users report better success with "Multi-instance" drivers rather than "UMDF" drivers in certain environments.

Clone vs. Genuine: Many 9780.Z5 units are "clones." If your software asks to update the firmware and you have a clone, decline it, as it can "brick" or lock the interface.
