The sata protocol does not show any indication of working feedback just random lights on the ATA status. The SSD was made 10DEC2019. The electronics test ok as per the above testing guide but the SSD shows a problem in the controller chip with heat at almost 40deg. A chip swap was performed but the memory chip would not read.
