The Actia PSA XS Evolution is a high-end multi-brand diagnostic interface, widely used for deep-level vehicle diagnostics (especially for PSA Group vehicles: Peugeot, Citroën, DS, and Opel/Vauxhall). The file 9780.z5 refers to a specific firmware or driver package version for the device’s internal USB-to-VCI (Vehicle Communication Interface) chipset—typically an FTDI or STMicroelectronics based controller.

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. |
