What does this fault code mean?
The DC/DC converter control module has found an internal fault that stops the converter from working as it should. The fault lies in the control module itself, not in the wiring around it. The code is only stored once the fault is confirmed, and charging of the high voltage battery is affected.
Possible causes

What you can do
