The PSA Interface Checker (also known as the "VCI Checker") is a utility tool used by owners of Peugeot and Citroen vehicles to identify the firmware version and hardware revision of their Lexia 3 / XS Evolution diagnostic interface. It is primarily used to determine if a clone interface is a "Revision C," which is necessary for compatibility with newer versions of DiagBox software (7.0x and higher). Download Links

Because this is legacy dealer-level software often shared in enthusiast communities, official public links from PSA are generally not available. You can typically find it through the following community sources:

French Car Forum: A primary hub for PSA diagnostics. Users often share links to 32-bit and 64-bit versions in specialized threads.

Google Drive Archive: Some community members maintain shared repositories for PSA Interface Checker Install.

or PP2000 but has significant technical hurdles for modern users. Pros:

Firmware Verification: Indispensable for checking if your VCI hardware can handle firmware updates without "bricking" or losing communication with the car's BSI (Built-in Systems Interface).

Revision Identification: Confirms if you have a full-chip "Revision C" interface, which is required for 2014+ model year vehicles.

Lightweight: A very small executable that does not require a full DiagBox installation to run. Cons:

OS Compatibility: Highly temperamental; it is designed for Windows XP or Windows 7 32-bit. Running it on Windows 10/11 often requires Compatibility Mode or a Virtual Machine.

False Readings: Lower-quality clone interfaces may report "Revision C" in the checker even if they lack the internal hardware components required for newer CAN-bus protocols.

Manual Handling: Firmware is normally updated automatically by DiagBox. Using this tool to manually "flash" your interface is risky and can permanently disable the device if the wrong file is used. Best Practices for Use PSA Interface Checker and Lexia Version - French Car Forum
