☐ Launch checker before DiagBox. ☐ Confirm “Vehicle Voltage: 12.4V – 14.2V”. ☐ Check “Latency (Avg)” – must be under 10ms. ☐ Run “Extended Test” for 30 seconds – no frame drops. ☐ Save the .psalog to your desktop as a backup.
| Vehicle | Year | Interface Type | Result | |---------|------|----------------|--------| | Peugeot 308 (T9) | 2018 | Actia OEM | Pass all tests. Latency <2ms. | | Citroën C3 (II) | 2012 | Full Chip Clone (FT232RL) | Pass after driver rollback to v2.12.24. | | DS 5 | 2016 | Chinese “Red VCI” | Partial pass. CAN test OK, K-Line failed. | psa interface checker 4.4.0
Conclusion: For any vehicle built after 2013 (with full CAN bus), 4.4.0 is rock-stable. For older hybrids (e.g., C-Multispace) with mixed protocols, run the checker in “Loop Test” mode for 5 minutes before critical programming. Stellantis has hinted at a new diagnostic architecture for 2025, moving toward cloud-based VCI management. However, the PSA Interface Checker 4.4.0 will likely remain relevant for at least another five years due to its offline capability. No version 5.0 has been announced as of this writing. Therefore, mastering 4.4.0 is a long-term investment for any PSA specialist. Final Checklist: Before You Flash That ECU Run through this 60-second protocol using PSA Interface Checker 4.4.0: ☐ Launch checker before DiagBox
