Hello all, new to the forum here and looking for some help with a problem I'm having. My wife has a 2011 Rogue and the other day while she was out and about it wouldn't start up for her. I went to meet her to check if there was anything I could do, but eventually had to have it towed home. Once home I started diagnosing it since I'm a bit mechanically inclined and typically work on my own cars. First thing I did was hook up the OBD2, and for some reason it wouldn't read. I know it worked previously, so immediately I'm thinking, "don't tell me it's the ECU."

I proceed to break out the Haynes manual for more troubleshooting and get to the ignition section. I determined that I was getting no spark on two cylinders, which the Haynes manual says is, "An ECU problem beyond the scope of this book and to take the car to a qualified mechanic." Anyway, just to confirm I had it towed a dealer, and some diagnostics later they determined the same thing.

Now here are my questions:

1. If I got a used ECM would it work? I ask this because another person on this forum stated they couldn't get a used one to work on their car.
2. If I were to get a used ECM/PCM from the same year and model what would I need to have reprogrammed? I'd most likely take it to a shop or dealer to do the reprogramming. I just wan't to know if I'd have to have anything re-programmed at all really. I.e. the intelligent key system, etc.

Only reason I want to go the used route is that they're trying to charge $1500 to put in a new ECU, when I know I can get at used one for $100 and do it myself.

Thanks for any insight.

Many years later. How did you fix this? dealership?

First thing to check with a non-communicating ECM is the ECM fuse. It's under hood in the IPDM, not in the cabin. Usually labeled "ENG CONTROL". If that fuse is good and has power, pull up the wiring diagram and check the output wires coming out of the IPDM from the ECM Relay. If those have power then it may be a bad ECM, otherwise it's a bad IPDM.
