I-Key system fault.
I’ve gotten this message twice now in the past month in my 2015 S.
The first, a couple weeks ago, occurred halfway through the start up jingle, with a clunk under the hood.
The second, just yesterday, but I didn’t notice any sound due to ambient noise.
Both times was over 90 degrees F outside and I was either already rolling down the windows or the a/c was already on during start up.
I get a bunch of DTCs and the car won’t shut off and tells me apply the parking brake.
Researching MyNissanLeaf posts and other forums, I find a variety of possible causes.
I can eliminate the 12v as it’s new, all the connections including ground are clean and LeafSpy shows it healthy with no parasitic drains.
Both FOB batteries have been replaced and they each work normally.
I see no evidence of water ingress anywhere or obvious relay damage.
I suspect a bad relay, but it could also be the IPDM, or something else entirely.
Both times I was able to clear the DTCs and then it worked normally.
Although, I had to clear the lower DTCs first.
They’re in alphabetical order.
I could only clear ABS and Brake last.
By the time those two remained, I could shut the car off.
I have no experience pulling and testing relays, but I intend to learn. Any tips would be appreciated. I’m already researching this online.
I’m not sure which relay is the ignition relay or how exactly to test it with my multimeter.
No idea if I can test the IPDM, but it seems to be a simple plug in operation.
I don’t hear any unusual noise under the hood such as relays clicking.
I’d rather not start replacing things without knowing if it’s the cause.
I try to avoid the dealership except as a last resort.
At this point it’s random and occasional and I can rectify things with LeafSpy, thankfully.
It’s 8 years old and just passed 50k miles, so it’s not entirely surprising.
At least others have reported similar problems.
Thanks for any suggestions.
I’ll update this post as developments progress.
