I don't know much about ABS so excuse anything strange I say.

roomate let his clutch fluid run dry and started messing up and compeletely stopped working, and at the same time ABS acting up. It keeps running, little pump or motor in it keeps runnign even once engine is turned off, have to pull the fuse to stop it

this is in a 240sx '93 5speed. I'm posting here cuz im not a member of the 240 forums and thought it might be a simliar symtom you maxima 5sp owners might hvae experienced.

We refilled his clutch fluid and everything with that is great, driving good again and he can shift gears good. but the ABS is still acting up

we disconnecte dthe battery for an hour or so to hopefuly reset computer, but didn't work, reconnected and put fuse in and the ABS unit started running again

 

Sounds like controller got fried
