So those are "S" not 5 as in step 1, step 2, step 3, etc if you hook it back up and start the "Customer Service Program" per the instructions at the top of the page the display will read out the step its on, it will do that step for the time indicated in the 3rd column and it will be doing the action indicated in the last column, then it will move on to the next step. This allowes you to watch and listen to each step to make sure its doing what it should. Find one that is not and you probably IDed the issue.
With the procedure listed you won't have to touch the hot circuts, and you shouldnt, just listen and observe, make note of any action that is not doing what is described.
A "hot" circuit means one that has the power on.
