The ipdm is the power distribution module. It contains fuses, relays and control modules. To me it is a stupid way of doing things as your relays that are built in are not replaceable. In most other car brands you can replace yhe headlight relay, the starter relay, the ac relay etc independently of any thing else if need be. In Nissans you have what you have now. I am not sure what happened to yours making it needing replacement. But let's say it was just the starter relay, you now have a huge cost to replace a $5 part.
