Off - discharge circuit is closed, precharge open, contactor open.
Acc - discharge circuit is opened, precharge circuit closed, contactor open.
ON - discharge circuit still open, precharge still closed, contactor closed.
There remains the overcurrent protection and isolation measures, but I will get to these in due course. The giant Bussman fuse is on the positive, but I can't see how a short which generates an epic plasma ball is going to be somehow less catastrophic thanks to the fuse.
