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.


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. 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.

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.

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.
