Actia Psa Interface Driver ✮

The Actia PSA interface driver is a specialized software component that enables communication between vehicle diagnostic applications and electronic control units (ECUs) on PSA Group vehicles (Peugeot, Citroën, and related Stellantis platforms) via Actia-branded hardware interfaces. Actia, a manufacturer of automotive diagnostic tools, produces interfaces that connect to a vehicle’s diagnostic port (typically OBD-II) and present a transport layer—USB, serial, or network—through which diagnostic commands and data can be exchanged. The driver implements the low-level protocols, device enumeration, and data framing required for higher-level diagnostic software (such as workshop tools, service applications, or aftermarket scan tools) to interrogate ECUs, read and clear fault codes, view live sensor data, and perform service functions.

Most DIY mechanics and independent shops use aftermarket clones of the Actia Evolution XS interface. True OEM interfaces use proprietary drivers bundled with authorized software. Clone interfaces, widely categorized as "Full Chip" or "Lite" versions, rely on specific USB driver variations (often modifying standard Windows USB serial drivers) to trick the software into recognizing the device as an authentic Actia tool.
