"Loose pin error" when [Production/service final calibration] finished.

[suzukida46]

Hi,

I'm using multiecuscan and ELM327 for my Alfa 147 selespeed.
I've tried [Production/service final calibration] and it seemed to work. However, when it finished, it said "COMPLETED" and "Loose pin error".

Question: what does "Loose pin error" mean? What should I do?
Please let me know.

Best regards,
