If you’re working with PSA Group vehicles (Peugeot, Citroën, DS, or Opel/Vauxhall), you’ve likely encountered the complexity of diagnostic hardware. When it comes to the Lexia 3 / PP2000 or Diagbox systems, the "440" designation is the gold standard.
Here is a deep dive into what the PSA Interface Checker 440 Verified status means and why it’s essential for modern car diagnostics. What is the PSA Interface Checker?
The Interface Checker is a small utility program used to communicate with your Lexia 3 VCI (Vehicle Communication Interface). Its primary job is to identify the hardware version and the firmware version currently flashed onto your device.
Since Peugeot and Citroën frequently update their official Diagbox software, the hardware needs to be "seen" as authentic and up-to-date to function correctly. The "440" Signature: Why It Matters
In the world of PSA diagnostics, "440" refers to the specific hardware revision—specifically the 921815C/ firmware.
Evolution: Older interfaces were often labeled as "B" versions. While these worked for older cars using Lexia 3 or PP2000 software, they frequently fail or "timeout" when used with newer versions of Diagbox (v7.xx, v8.xx, or v9.xx).
The "C" Revision: The "440" verified status indicates that your interface is a Full Chip Revision C. This is the highest grade of clone or aftermarket hardware, designed to mimic the original dealer tool perfectly. Why "Verified" is the Keyword
You might find many Lexia 3 cables online, but not all are created equal. A 440 Verified unit ensures:
Full Chip Architecture: It contains all the necessary optocouplers and relays (usually 12 or more) required for stable communication.
Firmware Compatibility: It can be flashed with the latest firmware (e.g., 4.3.7) without "bricking" or being blocked by Diagbox.
New Model Support: It allows you to diagnose vehicles produced after 2016, which often require the specific "C" revision handshake to access all ECUs. How to Use the Interface Checker
If you have the utility, follow these steps to verify your hardware:
Connect your Lexia 3 VCI to your PC via USB (you don't necessarily need to be connected to the car). Run the PSA Interface Checker executable. Click on "Activate" or "Read".
Look for the Reference Serial. If it shows 921815C/, you have the coveted "440" compatible hardware. Troubleshooting Common Issues
If your interface is not showing as "440" or "Revision C," you may experience: Initialization errors when opening Diagbox.
The software asking you to connect a VCI even when it's plugged in.
Inability to read certain modules (like the Airbag or ABS) on newer CAN-bus vehicles.
Pro Tip: If your hardware is a Revision B, there are "flashing" tools available in the enthusiast community that can sometimes upgrade the software logic to C, but this only works if the physical Full Chip hardware is present inside the plastic casing. Final Verdict
For any serious DIY mechanic or independent shop, the PSA Interface Checker 440 Verified status is the benchmark for reliability. It ensures that your Diagbox installation remains stable and that you can perform advanced functions like telecoding, ECU flashing, and key programming without the risk of a connection drop.

The PSA Interface Checker is a specialized utility used by automotive technicians and DIY enthusiasts to manage the firmware of the Lexia 3 (XS Evolution) diagnostic interface. This hardware interface is the primary tool for communicating with Peugeot and Citroën vehicles via software such as DiagBox, Lexia, and PP2000. Purpose of the Tool
The main function of the PSA Interface Checker is to verify and update the internal software (firmware) of the OBDII adapter. It is essential for:
Version Verification: Identifying the current firmware version installed on the device.
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).
Firmware Flashing: Manually "rolling back" or upgrading the firmware to match a specific software version.
Recovery: Fixing devices that have become unresponsive ("bricked") due to failed automatic updates. Key Technical Terms
Reference (Serial): Often seen as "921815 C" or similar. The "C" indicates the hardware revision capable of running the latest diagnostic features.
Init KO / Init OK: These are status messages within the checker. "Init OK" means the computer has successfully established a handshake with the interface via USB.
APPLI Software: These are the binary files (.HEX or .VCI) loaded through the checker to update the interface's internal logic. Critical Usage Warning
For users of clone (non-OEM) interfaces, the PSA Interface Checker is often used to disable automatic updates. If a clone interface attempts to update automatically via an internet-connected DiagBox installation, it can "black-list" the device or cause it to stop functioning.
Technicians often use the checker to flash Firmware 4.3.0 or 4.3.2 to ensure stable communication with the vehicle's ECU.
The "PSA Interface Checker" is a niche but critical utility for Peugeot and Citroën owners who use Lexia 3 or DiagBox diagnostic tools.
