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.
