Perhaps you mean D+/D-? You won't get very far if V+/V- aren't supplying any current.

Actually, V+ (the correct name is Vbus) not supplying any current is the correct initial state for a USB-C socket. It instead provides a small current on each of the two CC pins (usually through a pull-up resistor on each pin), and only after it detects that the other side is drawing that current (usually through a 5.1kΩ resistor to GND on each pin) will it supply power on Vbus.
