Your salt water pool system read out is check system no cell power 2?

I'm really not too sure what you're asking. If you have a slat cell, the first thing to do is check the salt level. It should be reading between 3100-3500, nothing under or over. If it's an inline cell, be sure the cell is clean and free from debris. If it's dirty, pour a mixture of 2:1 muriatic acid and water into the cell, allow to soak for 5 minutes, then rinse.

If your cell is throwing a code, look at the owner's manual to see which code means what.
