So one plausible guess:

to check for shorts on this line. A reading of "0.000" or significantly lower than the expected value (often around 400-500mV depending on the model) indicates a short to ground. Steps for Repair: Locate the Short : Use a schematic tool like ZXW or PhoneBoard to find all components on the PP_VAR_USB_RVP Clear the Short : Frequently, a small decoupling capacitor (like pp-var-usb-rvp

: A component used for current sensing along this power path. pp-var-usb-rvp So one plausible guess: to check for
