The PSA Interface Checker is a utility used to verify the hardware and firmware status of the XS Evolution VCI (Vehicle Communication Interface) used for Peugeot and Citroën diagnostics. When a user refers to "440 verified," they are typically looking to confirm that their device is a "Full Chip" version capable of running higher firmware revisions required by modern software like DiagBox. Understanding the PSA Interface Checker
"Verification successful for the PSA Interface. The PSA Interface Checker has confirmed device compatibility (Status: 440 Verified). Firmware revision and serial reference are now active for diagnostic use with Diagbox software." For a Diagnostic Report/Log: psa interface checker 440 verified
Revision Identification: Determining if the device is a "Revision B" or the more desirable "Revision C" (which is required for compatibility with newer versions of DiagBox). The PSA Interface Checker is a utility used
Important: Even with 440 verification, you must use the correct software version. Verification does not bypass licensing or activation. You still need a valid DiagBox activation key or a patched version (if used offline). The software is primarily designed to perform three
: It identifies the current firmware version (e.g., 4.3.0, 4.3.3). Revision Identification : It confirms if your hardware is Revision B or the more compatible Revision C Firmware Updating
The Payment Card Industry Data Security Standard (PCI DSS) requires that all payment processing systems, including interface checkers used to validate the interaction between different components of these systems, undergo a thorough security assessment. The Product Security Assessment (PSA) is a critical process designed to evaluate the security of payment products, ensuring they meet the stringent requirements set by the PCI SSC.
The software is primarily designed to perform three critical tasks for the VCI (Vehicle Communication Interface):
