The interface checker does not just see if the USB driver is installed. It probes the hardware’s microcontroller, checks the CAN (Controller Area Network) transceivers, verifies the K-Line and CAN switching relays, and most importantly, validates the .

The PSA Interface Checker is a standalone utility engineered to safely of the Lexia 3 (ACTIA XS Evolution) hardware. : A specialized utility software used to identify

These are status messages within the checker. "Init OK" means the computer has successfully established a handshake with the interface via USB.

An interface that is has been tested and confirmed to behave exactly like an authentic ACTIA XS with firmware version 4.4.0 or equivalent. This verification is crucial because many sellers list “compatible with DiagBox” but their hardware fails when deep ECU coding (like injecting a new BSI or programming a key) is attempted. Here is why the verification process matters: The
