Yes, on earlier devices, that diagnostic also reads/writes on the serial port.
Attach a 1.8 volt, low voltage serial to USB adapter to the serial port - then exit from diags mode using the serial port copy of the menu.
The details of the serial port on the Kpw are indexed, pictured, and describe here.
As is a good (long) teardown video.
Check the "K5" prefix index in the sticky at the top of this forum.
Too technical? Return it to Amazon as "broke" for an exchange.
