hello guys, nice to meet you my name is Diego and I am writing from Italy. sorry for my bad English, unfortunately here in Italy the 350z is little known and I find myself in a bad situation.
because of my ECU burned I purchased a complete key ECU and immobilizer (black box driver's side) I put everything but the car will not turn, I could see that I have no power to spark plugs and I think it immobilizer operated. I saw that there are two control modules code number:
285963Y50
285912F000
I need to replace these two control modules?
thank you in advance

 

Welcome Diego- why did your ECU "burned"? I wonder if there's an underlying cause to your situation that needs to be addressed, but need more info. Also, is there Nissan dealership in your part of Italy? An experienced tech with a CONSULT III will more accurately diagnose your problem than any of us gathered around monitors and keyboards.

 

my unit has burned out due to a short circuit on the reels. I bought ECM with keys is everything else but the car will not start as if there were inserted the NATS. unfortunately here in Italy from me there are no dealer working on 350z

 

You English limits my understanding, but I'd guess if you purchased a new BCM unit and am trying to integrate it into your car, there will be problems. You'll need a CONSULT III unit to integrate the ECM and BCM to work properly. You need a specialist- maybe a Renault dealer can help?

 

ok i solved by eliminating the NATS with upRev thanks to all of you for support, you were kind.
