I am not sure if I have a fried VCU or not on my hands. I had the USB plug touch a live wire by accident and everything is dead now. I checked all the fuses in the fuse box and a couple others beneath the top plastic cover and they were all good. How can I test to see if the VCU is blown? Thats the only part that i can find that the USB plug is connected to looking at the wiring diagram.
