The PSA Interface Checker V3 is a utility tool used to manage the firmware of PSA XS Evolution (Lexia 3) diagnostic interfaces, which are used for Citroën, Peugeot, and DS vehicles. Its primary function is to identify the hardware revision of your device (Revision B or C) and manually update or downgrade its firmware to ensure compatibility with different versions of Diagbox software. Key Features
Hardware Identification: Determines if your interface is Revision B (typically cheaper clones) or Revision C ("Full Chip"), which is necessary for newer vehicles and full CAN communication.
Firmware Management: Allows you to check the current firmware version (e.g., v4.3.0, v4.3.3) and flash new firmware using .com files like appli.com or vci_updater.com.
Device Recovery: Can be used to restore the software of a "bricked" or locked clone interface if it was accidentally updated via the internet, which is forbidden for non-original devices.
Compatibility Switching: Enables users to "force" a specific firmware version to match a chosen Diagbox version (e.g., using v4.3.4 for Diagbox 7.66+). Download and Installation
The tool is often bundled with Diagbox installation packages or found on community forums. You can find it on community-shared sources like this PSA Interface Checker Download. Basic Setup Steps:
Install PSA Interface Checker Install.exe to create desktop shortcuts.
Connect the Lexia 3 interface to your PC via USB (no vehicle connection needed).
Launch the application and click Activate to detect the device.
Use Reference Serial to see your hardware revision (B or C) and Version to check current firmware. Important Precautions PSA Interface Checker and Lexia Version - French Car Forum

The official PSA Interface Checker V3 is copyright Actia/PSA. Downloading it from unofficial sources occupies a legal gray area. However, for independent repair shops working under EU Block Exemption Regulation (MVBER), using such tools is widely tolerated as long as you own a legitimate VCI.
If you are a professional, consider buying a genuine Actia interface (€500+), which includes access to the official PSA diagnostic portal and a signed copy of the Checker.
For hobbyists: proceed with caution. Always scan downloaded files with VirusTotal. A clean copy of the Checker should trigger no more than 2/60 heuristic detections (usually false positives related to driver access).
To put it bluntly: If you are running Diagbox on a clone interface without the PSA Interface Checker V3, you are working on borrowed time. A single Windows update or a minor electrical fluctuation during a firmware update can brick your VCI, costing you $100+ for a replacement.
By securing a clean PSA Interface Checker V3 download and integrating it into your monthly diagnostic routine, you ensure that your interface remains recognized, your sessions never drop mid-DPF regeneration, and your workshop stays productive.

PSA Interface Checker V3: The Ultimate Diagnostic Companion PSA Interface Checker V3 is a specialized utility designed for owners of the Lexia 3 (XS Evolution) diagnostic tool, used primarily for Peugeot and Citroen vehicles. This lightweight but powerful program serves as a bridge between your hardware interface and diagnostic software like DiagBox, Lexia, or PP2000, ensuring they communicate correctly with your car’s electronic control units (ECUs). Key Features and Functionalities
The primary role of PSA Interface Checker V3 is to manage the firmware of your diagnostic hardware. Its main functions include:
Firmware Verification: Instantly identifies the current firmware version and hardware reference (Revision B or C) of your Lexia 3 interface.
Interface Recovery: Vital for "unbricking" clone devices that may have been accidentally updated via the internet, which can often cause them to stop working.
Firmware Flashing: Allows users to manually change or update the internal software (firmware) of the adapter to ensure compatibility with newer versions of DiagBox.
Hardware Identification: Helps distinguish between original and clone interfaces by checking how the device responds to activation commands. Why You Need Version 3
If you are using a clone Lexia 3 interface (common in the aftermarket), you may encounter issues where the device is not recognized or cannot read the vehicle's VIN.
Updating to Revision C: Many modern cars and newer DiagBox versions require the interface to be flashed to Revision C.
Solving "Init KO" Errors: If your diagnostic software shows "Init KO" or fails to communicate with certain modules, the Interface Checker is the first tool you should use to reset or update the firmware. How to Use PSA Interface Checker V3
Using the tool is straightforward but requires careful attention to avoid further hardware issues:
Connection: Connect your Lexia 3 interface to your computer via USB. You do not need to connect it to the car's OBD port during this process.
Activation: Open the program and click the "Activate" button. This initializes the connection between the software and the hardware.
Check Status: Use the "Version" and "Reference" buttons to see your device's current state.
Selecting Firmware: If an update is needed, click "Select File" and browse to your desired firmware file (typically named APPLI.com or vci_updater.com).
Flashing: Click "Downloading" to start the flash process. This usually takes between 10 seconds and 1 minute. Wait until the system displays "OK". System Requirements & Installation
PSA Interface Checker V3 is highly compatible and typically included in many DiagBox software bundles.
Operating Systems: Runs best on Windows XP (32-bit) or Windows 7 (32-bit), though it can function on newer systems in compatibility mode or via virtual machines.
Drivers: Ensure the Actia drivers are installed. These are usually automatically installed when you first set up DiagBox.
Installation: Most versions are "portable" (no formal install required), but some packages use an .exe installer that creates desktop shortcuts for easy access. Important Safety Warning
Never attempt to update a clone Lexia 3 interface through the official DiagBox internet update prompt. This will likely lock your device. Always use PSA Interface Checker V3 to manually manage your firmware to keep your diagnostic setup safe and functional.
