(iPhone 14 series), which are known to short and pull this line to ground. Resistor Check : Locating the 10 Ω RVP resistor (often designated as PP_VAR_USB_RVP_TIGRIS_R

This specific signal would likely be used to enable a USB power switch or to monitor whether the variable USB power rail is active on the reference board design. pp-var-usb-rvp
