How to solve KTM Bench identified Bosch MEDC17 ECU failure

Today, one customer meet a issue below：
I have KTM Bench ECU programmer to test with different ecms
And always with the same message "Bosch MEDC17 (TC1724 /1728 / 1767 / 1782 / 1784 / 1797) Flash identification, entering reprogramming mode failure"
I have tested the same connection with another j2534 interface
And can connect with ecm obviously can't read
the ecu type is 1766.

Attach several images of the Bosch ECU type & its internal pcb, the connection diagram, the error messages:
