S-Mode stopped working for a while???
 

What up guys, I did a quick search and could not find anything about this so I'm gonna ask you guys. Last night being a show off I pulled into a big empty parking lot turned off the VDC and did a few doughnuts and a little drifting. After I was done I started to drive away and I heard a beap and notice the words S-Mode on the info screen to the Left. I hit exit then noticed the gear selecter screen was blank and the S was gone from the spot on the dash. I held down the S-Mode button but it still did not work and there was no syncro rev feature. I turned the car off then turned it back on. Still didnt work. Turned it off again and let it sit for a few minutes. When I turned her back on everything was back to normal and the syncro rev worked fine for the rest of the night. Any idea what happen guys?????

Problem
1)being a show off
2)I pulled into a big empty parking lot turned off the VDC and did a few doughnuts and a little drifting

Diagnosis,
Go to a properly sanctioned event, turn S-mode off along with vdc, then see if it happens again.
Oh, and there is no need to show off the Z does enough of that for you.

So the problem was me going into a parking lot and doing it in the first place HMMM that dont seem to answear my question but ok. And from the stuff you right I cant tell if your being serious, your telling me if I turn off the S-Mode from the start this wont happen??? I would still like to know why this happen.

P.S If this is gonna just be a bunch of post of people telling me I'm stupid and I should not do this, and this is why Z's crash all the time either dont post or LOCK THE THREAD. I did not crash my Z It was about 3am in the morning at an industrial park at a closed buisness. SO CHILL!!!

you need to visit a dealer and have them scan it for error codes. sounds like an electric problem or a software glitch.

If it happens again maybe. Or if it only happens when I do what I did LOL. It all works fine now. I just figured this happen to someone else and it was because there was so much slipping going on???

Get off your high horse. No need for your Dbag response.


I think the issue is just one of those things, and I was going to suggest reset the ecu but its already cleared itself. If you are really worried mention it to the dealer but I wouldn't be to concerned

LOL... Nah I'm not worried, just wondering if this was a common thing that happen when someone did something similar to what I did.

I'm on no high horse, all i was getting at was dont do it in a parking lot you never know when a person will walk out, who is monitoring the lot and or if a group forms. He was showing off...to people not to himself.

I wasn't being a dbag, i just was saying find a sanctioned event for the future, we all have fun, that is what the z is for it is just when and where.

Thats all. Glad everything is normal, but in all honesty, it makes no sense to me why you would post this, if your drifting around and twirling like a teapot something is going to eventually give, your lucky it was only your ecu for a couple minutes, and not one of your friends watching. Maybe the only person you were showing off to was in your car, thats still a big risk if you mess up.

Its all good. Dont get me wrong, its totally stupid doing what I did, but I did it and I did it safely, No poles, no traffic, no other cars, and yes it was for the person in the car with me, not a group of people. I also dont think I'm really gonna mess anything up on the car doing those things, unless of course I hit something. But these cars are getting thrown around all kinds of tracks all over the world with no problems. I'm sure a little drifting is ok. Plus I'm from Long Island, and not that this is an excuse but there is no motorsports out here, LI SUCKS.

i think your car was just dizzy from all the spinning.

LOL... Yea probably

I know what you mean, they have stuff in Jersey though, just a bit of a drive. I know how LI is... in that aspect.

I used to live in NY/CT, and had some family down there in LI, I know a Z can handle it, maybe something just freaked.

I was doing some frisky mountain driving and my smode went out. Drove home, unhooked bat for a couple hours, hooked bavk up and it worked fine. Then today i went out to head home from christmas vacation and the car threw up an smode error upon startup. Was it cold when you had the problem? Ive heard rumors that the smode fails a lot when temps are super low outside.

Never heard of this problem. One time my dog (he was a puppy at the time) stepped on the S mode button while I was driving and unknowingly turned it off. When I didn't rev match and quickly downshifted, he got launched into the dash :(

Maybe that's why he's special now.

:iagree:

:iagree:

I am also fairly certain that the owners of the parking lot upon which you were performing your experimentation are pleased with your tire marks. To me, it is no different than vandalism. I am sure you asked permission first, right?

I was told by a dealership that the Smode thing was a "known" issue. As i mentioned before they said it had something to do with it being retarded cold outside. This is at least backed by my 2 instances of it happening both being snowfall days. Other than that it doesnt seem to have any rhyme or reason, once while driving "2 months pass" then again randomly as im starting my car in the morning for a trip to the store. :ugh2: another nonsense inexplicable Z34 issue?

does it turn off during driving? will it stay on once your car is warmed up?

I would not be happy with that answer, that sounds pretty dangerous and a great way to lock your wheels up on snow or ice.

Happened to me once. It was not a cold day when it happened. I did a ctrl-alt-delete and all was well. Just turned it off and turned it back on. Hasn't happened since. I was driving moderately aggressive but the oil temp was not above 210-215 so it was not that aggressive. I have no idea why it happened but I have driven many different conditions, colder, hotter, wetter at many levels of aggressivness, from not to highly. So, knock on wood, hopefully that problem will not rear it's ugly head again.

I like the doughnut dizzy spell diagnosis. :driving:

There's a description of how the S-Mode system works, list of inputs/outputs, &c starting at page EC-107 of the FSM (2009 version). Might help you troubleshoot the problem.

No, the first time it happened i was driving it a little hard in the mountains, lits of stop and go tight turns. VDC off, but no wild drifting or anything. And randomly SMODE just appeared in the digi info screen on the left, and the little "s" next to my shift gear indicator went out. and every time i tried to press the button it would beep and flash SMODE. Tried turning off the car, nothing works. Except pulling the negative bat lead, or doing the peddle ecu reset.

Second time it happened was a couple months later, i just started the car up to go to the store and it instantly flashed SMODE for no reason, even though i had been driving it without issue for the last couple months. Did the ecu reset trick again and it is normal again. So i stopped at the dealer and they all scratched their heads and poked at the computer a bit like chimps until the lead tech said "oh yeah, thats a known issue when the car is really cold, or theres a fault detecting the sensors" so they checked all the physical connectors related to the aystem and they were all 100% fine. I got no definitive answer why. Not the mention, fauling once while driving and once during startup at complete random with months of driving between doesnt seem to be a sensor issue to me. Sounds more like an ecu issue.

Yeah. A bit like the traction light and brake light staying on for no reason. I call glitches.

if you drive a MT spiritedly the csc goes out.
if you drive a AT spiritedly the paddle goes out.
if you drive a CVT spiritedly you just look dumb.

:icon18:

Forgot that in the MT the pedals go out, and the SRM goes out

I am just experiencing the same issue. SMode turns on fine then after some aggressive downshifting I get the SMode 'failure' indicator on the dash. Turn the car off and let it sit for a minute and it works fine.

I really need to figure this out.

Do an ECU reset with the pedals.

I have a tune with ECUTek and have reset it several times using their reset...is there a difference?
