I you have an OBD2 reader it might be interesting to see if it set a code then cleared it. My 2015 Rogue would set a code then clear itself. The code was a bad O2 sensor. Turned out to be a connector getting wet issue.

 

So mine story with saying it was in a crash in the progress to ABS in a progress to fall system for C owners manual go to dealership

So mine story with saying it was in a crash in the progress to ABS in a progress to fall system for C owners manual go to dealership
But what’s interesting is I have zero fault codes on my vehicle nothing stored nothing in there it’s just freaking out.
when I got my oil changed they said that when it’s cold the sensors freeze it have an issue with correctly sensing. What I want to see is an official recall for this because it’s dangerous

 

If that would happen to mine, I'd take it to the dealer and have them hook it up to check. No sense in assuming on a brand new truck that it's OK now because it cleared up. It might never happen again or it might repeat at some point or one issue can develop into another issue.
I wouldn't diagnose anything myself. Don't take the chance, just go and have them check it out!

 

x2 on taking it to the dealership, as it is a brand new truck

 

I was only suggesting the OBD2 look-see as just to see what it says. You should never reset any codes for a vehicle under warranty and you should always take it in. The system logs a reset, it doesn't log a look-see.

That said if it did set a code and then the system cleared it you would know that when the dealer inevitably says "gee....we don't see anything" that the dealer is not being truthful.

"Trust but verify"

also a great idea to check for a code and jot it down in case they BS you

 

Waiting in the drive thru line when I heard a beep and “System Fault See Owners Manual” popped up for no reason

When you go the owner manual, it says:
It is recommended that you visit a NISSAN dealer for this service.

 

Same thing happened to mine 1500 kms on it it was a wire connection that came out in my driver side wheel well

 

Happened to mine about three weeks ago almost right in front of the dealer. I pulled straight in, they checked it out and ordered appropriate parts that will be in around 4-6 weeks. In the three weeks it's done it twice. And once, it saw something that was not there and it applied the brakes pretty quick before releasing them. That will scare you.

 

Just had mine checked out at the dealer for this same issue. Turns out I pressed down the brake too hard and triggered the break switch. They popped it back in place. 19,000 miles strong

 

So I guess you need to be careful if you have to panic stop or you'll trip a fault code in your truck?

We've had this happen twice to us so far. Once when my wife was driving so I don't know the circumstances. Once when I was driving and I barely pressed on the brake at less than 5mph while picking my wife up at the airport. Lights stayed lit up and warning message saying to check the owners manual until I parked it and shut it off. On restart everything was fine. Have about 7,500 miles on it so far.

 

You ever figure this out? Just happened to mine, same exact thing except I was sitting in park. 8/25/22

 

It’s nothing too serious to worry about. Just have the dealer check it for ya. Otherwise restarting the truck usually clears it.

 

Just happened on mine while crawling through a parking lot.

 

So is this specific scenario in regards to the brake switch or the radar sensor having an obstruction?? I have seen a few different threads on the forum regarding similar if not same situations?? Seems the dash lights up like a Christmas tree and a restart clears it with no codes to read later?? So is it this brake switch that is causing this or are there other variables I am missing here? Just trying to clarify as I'm sure others here are a bit foggy on this particular situation

 

Mine has been doing the system fault error randomly for a week. It came on today when it was 65f outside. I noticed the crash light comes on in the afternoon when the sun is hitting the front. If the road has a bend and gets out of direct sunlight, the light goes out. I have an appointment for next weekend.

 

Okay so after talking with my uncle (he's a Ferrari mechanic), it's in the rear wheel sensor making one of the wheels drag getting up to speed so one tire is trying to go while another in lacking behind, so when you let up off the gas and that tire finally gets up to speed the vehicle will go full throttle. Ferrari had it happen in some of their 360s. My uncle was actually the one who fixed this problem in the Ferraris. they didn't release a recall they changed the software and made it part of the service to kind of sweep it under the rug. now I know you're thinking that's a Ferrari not a Nissan. well, the Toyota Preus was having this same issue, I believe in 2014. this whole "system fault" is very dangerous and needs to be handled quickly as the car can accelerate on its own while the one tire tries to get up to speed. if you see these lights, come on my uncle suggests pulling, over and taking an uber (try not turning the truck off because if it reset it will cycle through its safety check on start and clears the codes). If your ABS or traction control light up solid with any car don't turn it off, take it right to someone who can scan into it. so, I asked how I can go about getting a fix for this he told me to talk to my cousin who works in the Lexus HQ, and he told me if enough of us call their cooperate office we can get an official recall. I say we all call Nissan corporate office and make offical complaints on this matter and we want it fixed. Our traction control and ABS systems should not be disabling while we are in the middle of driving, especially with the majority of us having it happen under 10k miles, some even as low as 3k.

 

I’ve had mine do this about a dozen times. I called the dealer and was told it isn’t serious, that I could keep driving the truck, but they are going to look at it next weekend when the do the recall work on my transmission. I’m at 14,600 miles.

 

All else fails...

3rd Gen Variable Voltage Charge System (VVCS) aka...

 

I had this same problem with all of these lights coming on. The dealer replaced the brake switch, and the problem went away. I still have one of the amber dash lights flash when I'm driving towards bright sun light. It's the lower left light on the speedometer (looks like 2 cars crashing).

 

I took it into the dealer this morning and the girl started tap dancing about it. They changed the oil and hooked it up to the computer and it pulled a code. They ordered parts and supposed to have them in before Christmas.

 

It's the brake switch. I thought about making a topic for it because it's a widespread issue but didn't. The Panasonic switch they used has been problematic among a huge range of makes and models the past year or two.

I was starting to have this happen daily. Popped the brake switch out and opened it up, both incredibly easy to do. What's happening is that two contacts in the switch are too close together and can eventually touch and short, causing the dielectric grease to get burned which coats the electrical contacts and causes an intermittent brake switch function. It'll reek of ozone when you open it.

The mechanism is ridiculously simple and virtually impossible to break, there is no point in replacing it. Just pop it out, open it up, clean out the burned grease, scrape the burn residue off the contacts, space the contact pins apart better, apply new dielectric grease, and then put back in. Problem solved.

The switch itself just twists out, it's the lower of the two on the brake stop post. Reach up, unplug it, give it a quarter twist and pull it out. It just has two plastic clips holding it together. You'll see what I mean when you get a look at it - it's comically simple. You could recreate one with a super cheap 3D printer to make the housing, a tiny piece of thin sheet metal, and a spring.

Anyway, this is the cause of this prolific error. You can take it in and get a new switch but its likely to happen again someday, while you can permanently fix it yourself in 10 minutes and with a 98c pack of dielectric grease from O'Reilly and some isopropyl alcohol.

 

Thanks for the info. I'm putting this on the "things to watch for" so a simple fix is always welcome. Appreciate it as I'm sure others as well

 

Mine’s in the shop getting this fixed as we speak. Apparently it was some weird voltage variation occurring somewhere in the truck (tech had to troubleshoot with Nissan engineers) but if someone reminds me tomorrow, I’ll post the service record in case it has anything more descriptive/accurate than a game of telephone with the service advisors

 

May I suggest this:

Waiting in the drive thru line when I heard a beep and “System Fault See Owners Manual” popped up for no reason as well as the ABS indicator and collision indicator. Turned the truck off then back on again and it went away. View attachment 341110

This just recently happened to mine. Last night I was driving home when 2 faults came up and my ABS, traction control and collision detection all came on. About 5 minutes later I came to a stop sign and pulled away like any other stop sign, and as soon as I got through the intersection the whole back end started fishtailing like crazy and I ended up nose first in a tree with all the airbags deployed. And this wasn’t on a crazy windy road or hill or anything it was a flat, straight road. I was on the phone with my mom using the hands free and told her it felt like the truck just took over and I had no control over it so if anyone has any other incidents like this please reach out to me as I want to know if the truck was at fault or if it was just a freak accident.

 

As I said the error is a result of the brake switch becoming intermittent. The car throws a fault because the brake switch is not activating while the brake lamp switch is, which lets the car know there is a fault. All this fault state does is disable the ABS system and by proxy the traction control system and collision avoidance system because they are reliant on ABS.

I can't speak to what happened to you. But the truck just throwing itself into a tree on its own is kinda hard to swallow. As I said all this fault state does is disable ABS and related systems. Not calling you out or anything but maybe don't go right at the insurance company with the truck threw itself into a tree because they aren't buying that.

A. Was it icy?

B. Get a dashcam. This is why you have dashcams and why they are important. If what you said is true that could have been invaluable footage to have for both your insurance company and for Nissan corporate.

 

Had mine into the dealer Saturday, they said the system fault issues was addressed and I shouldn’t see it again, we shall see.

 

Here is my service receipt from the warranty work. Looks to be the brake light switch, with some harness probably replaced for extra measure (which apparently takes a lot of labor to access). See the top line for parts, TSB, and codes. With parking pawl, the service was 1.5 days once the parts were delivered.

 

Just got this error on my 22 frontier 10k miles I drove straight to the dealer when it turned on knowing that if I turn the truck off and then on the lights disappear, tech plugged In his computer and the fualt was tripped by the Brake lamp Switch , told me if it happens again to bring it back in which it will probably happen again doesn't happen often (3 times in 3 months ) but can be dangerous if it disables ABS , new collision assistance features and traction control

 

Read my earlier post. Open the brake switch up (not the brake lamp switch, though it is what throws the error) and carry out the steps I described. It'll take you 10 minutes and then you don't have to worry about it again. You cannot break the brake switch by disassembling it, that would be virtually impossible. It's a no risk simple fix. The longer you let it go the worse it'll get and the more surface oxidizing you'll get on the contact pins which will make cleaning them up harder.

 

OS,
For the ABS fault, get up under the dash (brake pedal) and make sure the "plunger" brake sensor is not cocked sideways and/or it is not too far "in" where just the slightest of bumping would trigger the ABS sensor. (there is a thread on this)
I now have a Traction control warning that goes off (every once in a while) when I turn left into a parking space,Gonna have to go back to dealer and see WTF that is about!!!!
The '22 Frontier is approaching a POS vehicle!!!!! like my '16 was.

 

😳Your 22 is approaching a POS vehicle like your 16 was. That's not good. What was wrong with the 16 ?

 

Snake,
On test drive vehicle shutdown, some sensor failed in the engine. They had to come tow it back (fixed it like in an hour). Got home and after like a week the rear 3rd brake light leaked like a siv (my '19 had this as well!!!), then the rear window leaked (they had to take the whole window/ light assy out and redo the framing!!!). From the leaking I got mildew in rear seat/ carpeting (they had to replace it all). Had several O2 sensor fails (had to have vehicle towed as it wouldn't run worth chit).
I didn't keep it even a year!!!!!!
The '22 year is up in Feb it "might" make that but if they can't come up with fixes for the USB issues that could be a deal breaker.

 

Sorry all that happened. Some vehicles have glitch after glitch then same model somebody else has runs without any issues at all. It happens, why i don't know. I once bought a brand new boat out of state and brought it home to my state. It sat in garage til i got registration and all paperwork worked out at DMV. I take boat out on maiden voyage and first time out the motor burns up, actually the powerhead. Me and salesman from the state i bought it had taken boat out and it ran fine before i purchased it. I had nothing but problem after problem with that boat. Why ? Who knows. I got rid of it and lost money on it. 😳😢😀

 

I am seeing this pop up on my screen when driving in 4LO. I'm not really off-roading or anything - I am just occasionally exercising the systems. I live on a gravel road, currently snow packed. I put it in 4LO and slowly drive down the road. After a few hundred yards the "System Fault" pops up - with AEB and collision warning off or on, fully warmed up, any speed I've tried. I brought it up as something I wanted looked at while they did transmission recall at the dealer. They said they replaced the radar and tested it for 100 feet a couple of times - all good. It still does it and I am trying different scenarios to to try to find something I think is triggering it.

Has anyone else seen this happening in 4LO?

 

Yes. Several times. Descending Mauna Kea

 

Nice!

Before the fix, the fault lights were coming on almost every day. Now, no lights ever since I did the sensor clean/prong separation. 👍
