: The driver works hand-in-hand with firmware checking utilities (such as PSA Interface Checker ). To work with modern software versions, the hardware serial number must end in a " C " designation (e.g., 921815C ), as older " B " firmware variants are blocked by modern drivers. Core Software Compatibility
Without the correct 9780.z5 driver, the Actia PSA XS Evolution will either be unrecognized or limited to basic J2534 pass-thru functions without PSA-specific protocols.
: ACTIA IME provides official downloads for various XS Family drivers (e.g., PASSTHRU+ XS 2G, Basic+ XS), often requiring a serial number for specific versions.
Must use USB 2.0 ports. USB 3.0 ports frequently drop connection packages. Actia Psa Xs Evolution 9780.z5 Driver
Before diving into drivers, it is essential to understand how Windows perceives this hardware.
: The modern unified platform covering vehicles from 2006 onward.
Verdict The Actia PSA XS Evolution 9780.z5 driver is a competent and dependable communication driver for the XS Evolution hardware, enabling professional-level diagnostics on PSA vehicles. While installation and driver-signing hurdles can frustrate less technical users, once properly set up it delivers stable connectivity, low latency, and the protocol breadth required for everything from basic troubleshooting to advanced calibration tasks — assuming the diagnostic host software provides those higher-level functions. : The driver works hand-in-hand with firmware checking
You need to use a tool called PSA Interface Checker . Load the tool, check your version, and flash the firmware to Revision C using the APPLI.HEX file found in your Diagbox directory. Error: Yellow Exclamation Mark / Code 52
To ensure your Actia XS Evolution is communicating correctly: Open Device Manager. Look under Universal Serial Bus controllers.
: Avoid external USB hubs. Plug the VCI directly into a primary port on your computer. If the disconnection occurs only when hooked up to a vehicle, the internal optocouplers of a replica board may be failing under load. 2.

Before diving into driver files, let’s clarify what you are working with. The (often referred to as the "Pass-Thru" or "XS Evolution") is a VCI (Vehicle Communication Interface). It bridges the OBD-II port of a PSA vehicle to a PC running software like DiagBox, PP2000, or Lexia.
| Issue | Probable Cause | Resolution | | :--- | :--- | :--- | | | Driver mismatch or COM port conflict. | Manually install drivers via Device Manager pointing to the Diagbox folder. Ensure the COM port number is within the supported range (usually COM1-COM8). | | Windows 10/11 Compatibility | Newer OS versions often block the unsigned legacy drivers. | Disable "Driver Signature Enforcement" in Windows Advanced Startup options before installing. | | Firmware Update Failed | Corrupted connection or wrong Diagbox version. | Do not unplug the device during firmware updates. If bricked, specialized "Actia Updater" tools may be required to recover the board. | | API Not Found Error | Missing J2534 DLL files. | Reinstall the Diagbox software ensuring Administrator rights were used. |
