Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
do you have a test light to check fuses?
Also let me know if this is a coupe or sedan?
There should be 3 power sources at the OBD2 connector. If you have 2 and not 3, you could be looking at a Ecm issue. Hang on while I check something for you.
No, it can be a simple part of the internal circuits. Did you check all 3 fuse box location?
You have the IPDM as well. Hang on..
That image shows the two fuse box location under the hood.
If you checked all fuses, you are most likely looking at a Ecm issue. What you do to verify if you have a Ecm issue is to unbolt the Ecm take the connector apart so you can back probe the Ecm connector and do a Ecm terminal Reference check. This checks all input and output signals at the Ecm so you can determine if the Ecm is the issue or not.
That is the Ecm terminal Reference check. Please download that information as I do not keep it in my dropbox very long.
What I normally will do is print this out and bring it to the vehicle and when I check each pin, I write my findings on the paper and when I am done I compare all the readings I got verse the readings I am suppose to get. That would tell me if it's a Ecm issue or not.
If you have any more questions on this, please feel free to ask.

How many miles do you have on the car?
the Ecm has a 8 year or 80k mile warranty. So if you are with in that, and the Ecm is the issue, then it would be replaced under warranty.
So it maybe something to have the dealer check. Cause if it is the Ecm, it is covered under warranty. Just make sure when you bring them the car to have it checked, you bring all your keys. If the Ecm is replaced all the keys will need to be reprogrammed to the new Ecm.
Hold on a min please.. having computer problems...just jumped on my phone to reply to you
Yes that is a factory warranty for the Ecm
Sorry for the delay, it looks like my Internet provider is having issues. So I am on my phone now.
Do you have any more questions on this?
Yes, the Ecm and the Catt Converters have a 8 years or 80k Mile warranty.
That is a Factory Warranty for those parts.
Yes, This is a Factory warranty. So as long as this is not a Salvage car, this part would be cover if defective.
The dealer will want you to authorize diagnostic time. They may start with 1 to 2 hours labor. So be prepared for that. But if it's the Ecm, they should not charge you for the diagnostics.
If they try to, you can call Nissan on them at 1-800-Nissan-1
