Psa Xs Evolution 9780.z5 Driver «Plus – CHEAT SHEET»
Many online forums incorrectly suggest using a generic “Psa Xs Evolution” driver. However, the revision includes modified timing parameters for a slower external clock (12 MHz instead of 20 MHz). Using the wrong driver version results in:
Even after installation, you might face connection issues. Here are the three most common scenarios:
Because older Lexia-3 code cannot run natively on 64-bit systems, users must run Diagbox inside a virtual machine (like VirtualBox or VMware). In this setup, the driver must be recognized by the host machine first, then successfully passed through to the guest operating system. Step-by-Step Driver Installation Guide
: Drivers typically work best on Windows 7 (32-bit) for older software versions. Modern versions (V9.85+) can run on Windows 10 and 11 , but often require a Virtual Machine (VM) to ensure stability and compatibility.
software, this driver acts as the bridge that allows your PC to communicate with the vehicle's electronic control units (ECUs). Key Features and Capabilities
However, after thorough research across technical databases, driver archives, and PSA (Pressure Swing Adsorption / PSA Peugeot Citroën) contexts, by that exact name exists in public records.
Unlike universal OBDII scanners that only read generic fault codes, the 9780.Z5 interface, when paired with the correct software, allows you to:
: The drivers are generally compatible with Windows versions from XP through Windows 11 (32-bit and 64-bit).
| Potential cause | Solution | |----------------|----------| | DiagBox 9.xx often contains firmware updates that corrupt or disable clone 9780.Z5 units. | Uninstall DiagBox completely. Use a cleaner tool (e.g. “DiagBox Uninstaller 101”) to remove registry traces. Then install DiagBox 7.83 or 7.85 instead. | | Incorrect COM port number. The diagnostic software expects the VCI on a specific COM port (usually COM1–COM4). | Open Device Manager, note the COM port number assigned to “USB COM Board Evolution”. If it is COM5 or higher, go to its Properties → Port Settings → Advanced, and change it to COM1, COM2, COM3 or COM4 (whichever is unused). | | Driver conflict from a previous installation. | Use a driver cleaner utility (e.g. DriverStore Explorer) to remove all old PSA USB COM driver entries. Then reinstall the correct driver. | | Firmware corruption. Connecting a clone 9780.Z5 to DiagBox 9.xx may have “updated” its firmware, rendering it inoperable with older software. | This is serious. Some users have recovered their VCI by reflashing the firmware using PSA Interface Checker and a known‑good firmware file (often shared on forums like NLC‘s thread). Others find the VCI permanently dead and must buy a replacement. | | Windows driver signature enforcement blocking the driver. | On Windows 7/8/10, reboot and select “Disable Driver Signature Enforcement” from the F8 boot menu before reinstalling. |
: DiagBox automatically launches legacy software like Lexia 3 (for older Citroëns) and PP2000 (for older Peugeots) based on the vehicle model being scanned.
Drivers are rarely distributed as standalone packages; they are embedded inside the Diagbox installation directory.
Most aftermarket tools come with a CD labeled "DiagBox 9.85" or similar. The disc usually contains an Actia folder with the .inf installation files. However, these discs often contain malware or corrupted drivers. If you use this method, scan the disc thoroughly with antivirus software first.
Native installation is only stable for Diagbox v9.xx+. Drivers require disabled driver signature enforcement. 64-bit (x64)
or higher environments, which include the legacy Lexia and PP2000 interfaces. Important Considerations Firmware Updates
However, the hardware's effectiveness is entirely dependent on its connection to a Windows PC, requiring the correct and software suite (DiagBox/Lexia) to function. This guide covers everything you need to know about setting up and troubleshooting this crucial tool in 2026. 1. What is the PSA XS Evolution 9780.Z5 Driver?
