Well I have an update for you guys, this BCI malfunction as you can read in my last post was resolved in my 2017 Nissan Armada Platinum by replacing the brake light switch, yes that simple, well the one I bought a few months ago went bad too, so off to the dealership I go again, remember my Armada was 500 miles outside of the warranty and well I had to pay like $60+ for a replacement switch. Now same story, but here's where if you are out of warranty it might be helpful, the switch itself is a simple contact type switch, I took it apart and was able to see that some contacts had become dirty and that would explain the intermittent performance. I sanded the contacts that had some build up on them and cleaned out the dirty dielectric grease, then a further cleaning. Finally prior to assembly I applied new dielectric grease and put some on the contact shaft to prevent dust from getting into the switch, installed it back into the truck, and the codes are gone and everything is working as it should.

Thanks so much for your updated post!!! Hopefully I can just give your post and picture to a mechanic friend of mine and this will take care of the same problem I'm having with my 2019 Nissan Armada.

I just joined to the forum to inform you all that the BCI thing happened to my wife’s 2017 Armada. It happened 2-3 times, I changed the battery of the key 3 months ago and it hasn’t happened again.

You lose nothing but 5 mins and $5 by giving it a shot.

I have a 2019 Armada with 64,000 miles. I changed my battery to my remote because it completely stopped working. This week my BCI Malfunction has come on 5 times. Goes away when you turn it off but seems this week to always come back on. Have noticed it not starting the first time like normal and sometimes while driving it feels like there may be a little play/give when applying brake to stop.
