What does failure code: 4SNS/1/40000000:VDOR-18.543 mean?

Hi guys, I am working on a Mac Book Pro (late 2010) and ran the hardware test on it.
It results with this failure code: 4SNS/1/40000000:VDOR-18.543, which did not appear with my power supply unconnected.


I just wanted to check, as also my LAN adapter and SD card reader don't work.


Thanks for your help
