Yes, they mean the same thing. If the system is in need of a recharge, the low pressure switch will not allow the compressor to engage. This prevents the compressor from being damaged. When you do "jump" the terminals, you should see and hear the compressor "clutch" engaging. If the clutch does not engage, it usually means that their is a problem with the clutch or compressor. Word of caution, do not run the test for more than a few seconds at a time, or you could end up damaging the compressor. Good luck
