Module M1586 had passed the full qualification on 20/02/27. I had had to re-insert the cable in the Molex connector for it to become programmable.

On 2020/03/09, I tried to re-test M1586, but it was not programmable. Visual inspection revealed nothing to me. I did re-insert the cable once again, but this time this did not help.

Maybe one should try again re-inserting the cable.

Maybe these issues are an indication that the module (MOLEX) is flaky.


Most likely the cable contacts caused such behavior since they look damaged.
After changing the cable module do not show any more problems.
