The D0901 error is simply a SupportAssist analytical notation. This is not a hardware fault. In future, Dell will remove these SupportAssist analytical notations from the diagnostic results.
Did you ever get an answer on this? I have a Dell 8700 XPS desktop, too and just saw I got that error when I ran the Support Assist. Cables - Functional Tests - D0901. Mine passed every time April-June 2022. Now all of a sudden, both times I ran this in July have it failing the Cables functional test.
