| | 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. |

The Actia PSA interface—commonly known as the Lexia 3, PP2000, or Evolution XS clone—is the hardware backbone for diagnosing Peugeot and Citroën vehicles.
