Not even an explanation using the nanites that the Reapers seem so fond  of using? Twould make sense that the relays had little colonies of the buggers in them maintaing them for all those centuries. Both the Reapers themselves and their mangled minions contain nano-machines to facilitate command-and-control functions, why not use that against them?
