Also, J1001 on the JACK board has been changed with it.
When exchanging the J1001 on the JACK board, check whether or not Q1001 on the JACK board is mounted.
J1001 on the JACK board when Q1001 on the JACK board is mounted is Former type.
J1001 on the JACK board when Q1001 on the JACK board is not mounted is New type.
