The PSA Interface Checker is a specialized utility tool for the Lexia 3 (VCI) diagnostic hardware used with Peugeot, Citroën, DS, and Vauxhall vehicles. It is primarily used to identify, manage, and recover the firmware of the diagnostic interface itself, especially when using unofficial "clones" with software like Diagbox. Key Functions

VCI Identification: The tool allows you to "Activate" the connected hardware to identify its serial number and hardware revision—specifically whether it is a Revision B or Revision C.

Firmware Verification: It displays the current firmware version (e.g., v4.3.0, v4.3.3) installed on the interface.

Emergency Recovery: It is a critical tool for "unbricking" or restoring a VCI if its firmware was accidentally updated via the internet, which often causes unofficial hardware to stop working.

Manual Flashing: Users can manually select and "Download" specific firmware files (like appli.com) to ensure compatibility with different versions of Diagbox (v7, v8, or v9). Context for 2021 Usage

While older versions (like v4.3.3) were common for years, "2021" refers to updates needed for the hardware to communicate with more modern PSA vehicles (e.g., Peugeot 308 2021 models) or to work with newer software builds like Diagbox v9.12x or higher.

Revision C Requirement: For modern vehicles (post-2015/2016), the hardware must typically be flashed to Revision C and use a firmware version compatible with the CAN-bus architecture of those cars.

Interface Evolution: In 2021 and beyond, many users transitioned to using pre-configured Virtual Machine (VM) versions of Diagbox (like v9.91 or v9.150) which require the VCI firmware to be specifically managed via the Interface Checker to avoid connection errors. Standard Usage Steps

Connect VCI: Plug the Lexia 3 interface into your computer via USB (it does not need to be plugged into the car).

Activate: Open the Interface Checker and click Activate; the status should change to "Inisialisation OK". Check Version: Click Version to see your current firmware.

Flash (If Needed): Click Select File to browse for the desired firmware file, then click Downloading to flash the device. The VCI light typically flashes during this 10–60 second process.

Key Focus Areas for the 440:2021 Standard

The 2021 revision of the 440 standard introduced stricter requirements compared to previous iterations. When running the Interface Checker, engineers should pay close attention to these common failure points:

  1. Diagnostic Service Timing (ISO 14229 / UDS): The 2021 standard tightened the timing windows for UDS (Unified Diagnostic Services) responses. The checker validates P2 and P2* timing parameters. Ensure your ECU does not send responses too early (violating minimum separation time) or too late (causing a timeout).

  2. Network Management (NM): Verification of the OSEK/ AUTOSAR Network Management logic is crucial. The checker will validate the ring logic, sleep transition times, and repeat message request handling. A common failure in 2021 audits is the mishandling of the NM Coordinator role in complex topologies.

  3. Security Access: With cybersecurity becoming a focal point, the Interface Checker now scrutinizes the seed-key exchange mechanism more aggressively. It verifies not just the success of the unlock, but the delay algorithms and the handling of invalid attempts.

  4. Signal Attributes and Roll-Over Counters: The tool scans the DBC/ARXML implementation against the standard. Specifically, watch out for "roll-over counter" behavior in periodic messages—the checker will flag if counters do not increment correctly or if the Cycle Repetition does not match the declared cycle time.
