Actia Psa Interface Driver Jun 2026

ACTIA PSA Interface Driver is the core communication software that bridges the gap between a vehicle's On-Board Diagnostics (OBD) system and professional-grade diagnostic software like Lexia 3, PP2000, and Diagbox

To ensure you never lose communication mid-diagnosis or during an ECU telecoding procedure, follow these industry best practices:

Setting up these drivers can be notoriously difficult due to legacy software requirements, operating system compatibility issues, and the prevalence of clone hardware. This comprehensive guide covers everything you need to know to successfully install, configure, and troubleshoot your Actia PSA interface driver. 1. Understanding the Actia PSA Interface Hardware

| | Likely Cause | Solution | | :--- | :--- | :--- | | Interface not recognized in Device Manager | Driver not installed, damaged USB cable (try the short cable), or faulty USB port | Try a different USB port (preferably 2.0). Check cable integrity. Use Device Manager to scan for hardware changes. | | Yellow exclamation mark next to ACTIA USB | Corrupted driver, or the loaded driver is incompatible (e.g., driver ending in 22.inf when 19.inf is needed) | Manual Update: In Device Manager, right-click the device → Update driver → Browse my computer → Let me pick . Choose the .inf that doesn't cause a yellow mark. | | Interface recognized, but no car communication | Faulty OBDII connector pins (4,5,6,7,14), missing vehicle power on OBD pin 16 (blown lighter fuse), or incorrect firmware version | Check vehicle fuses. Test with PSA Interface Checker . If serial ends with /B , the interface may be blacklisted for newer DiagBox versions. | | Green LED flashes once then turns off | Power issue from USB port or defective VCI. Also, the VCI may be detecting a short on the vehicle OBD bus | Connect the VCI to a different PC that does not have DiagBox installed. If the green light stays on there, the driver on the original PC is flawed. | | Error after Windows 10/11 update | Windows Update replaced a critical driver component (like an FTDI driver), breaking communication | Go to Settings → Windows Update → Update history → Uninstall updates . Roll back the problematic update. Or, uninstall and reinstall the DiagBox driver package. | | Error related to VMware or VirtualBox | The virtual machine has not been given direct access to the USB device connected to the host PC | In the virtual machine software, go to USB settings (or Devices → USB in VMware). Check the box for the "Actia PSA XS Evolution VCI" to mount it directly into the virtual environment. | | INIT KO message in Interface Checker | The VCI is completely non-responsive or bricked, often due to a failed firmware update | No standard software fix. This typically indicates a hardware failure within the VCI itself. | actia psa interface driver

Allows you to tell the car that a new part has been installed (e.g., adding a cruise control stalk, a new radio, or a tow bar). Actuator Tests:

. Specifically designed for Peugeot and Citroën vehicles, this driver ensures that the ACTIA XS Evolution hardware (the physical VCI) can translate complex vehicle data into a format your computer can understand.

) is the standard Vehicle Communication Interface (VCI) used for dealer-level diagnostics across Peugeot, Citroën, DS, Opel, and Vauxhall vehicles. Below is a technical report on its drivers and implementation. 1.

The Actia PSA interface acts as a translator between your vehicle’s On-Board Diagnostics (OBD2) port and your laptop’s USB port. When you plug the device into your computer, the Windows operating system relies on a specific device driver to recognize the hardware. Driver Types: Evolution vs. UMDF

Separate drivers for various ACTIA families (e.g., XS Family, Basic+ XS, Lite XS) are available for manual download from the official ACTIA IME Support Page for systems running Windows 8, 10, or 11. 2. Hardware Identification: Original vs. Clone
