DVC really turns off??
 

I made a rt turn and dug in good and started to get nice and squirly, then DVC stepped in.....only thing is it was turned off!! Is this normal?

what makes you think VDC stepped in?

Car backed off bigtime and traction control light started flashing, just like it does when I do the same and forget to turn off the VDC.

When you turn VDC off traction control is still on, but only at around 10% of the level it would be normally.

I thought the Traction Control light came on regardless of whether VDC (not DVC) was on or off.

Basically just letting you know hey your spinning your tires. I could be wrong though, I'll have to check later. I'm sure someone knows the answer to this though.

in the OM it says even with the VDC off, the ABS & ABLS (Active brake limited slip) will still operate. I dont mind the ABS, but the whole reson to turn of traction control is just that :(

Saved your a$$, though.

The hell it did!!......It ruined what I wanted to do ;)

Well that sucks. I hate not being able to control everything your vehicle does.

I know the traction light still flashes with VDC off but I did not know the throttle still shuts down too.

Yeah...it definitely is a drag. I like to get sprirted sometimes and this will put a damper on things! Shuda bought a 458 Ferrari! Turn that mannitino to "OFF" and you're on your own baby!!! No safety nets there! ;)

That's what Cristiano Ronaldo did when he crashed his ferrari on the way to practice...

If VDC is OFF, it's OFF unless you're stepping on the brakes. I've done a 180 on the track after cooking a turn, and trust me, the car wasn't helping me get out of it. If you step on the brakes, the VDC system reengages while the pedal is depressed though.

So I guess we debunked the ~10% traction control while VDC is off theory?

Maybe my car is malfunctioning!? I will have to try again to see what happens, but I read straight from the OM, which would back up what happened to me.

I have no problem spinning the tires until the cows come home or making the back end overtake the front with VDC off. However, last weekend I was coming into a corner during AutoX really hot with VDC off, and stopping the brakes got the back end loose and VDC straightened the car out. Also, when I did my 180 on track, brake application again immediately rectified the situation which was otherwise not really improving all that quickly (I was sideways until I hit the brakes and then I got the left-right-left-right-while-slowing-VDC-sensation).

Hmmm I don't follow you. If you hit the button, the VDC is off. The slip light might still flash due to the ABLS, which is a computer controlled LSD. It doesn't limit engine output directly, it just apply brakes to the wheel that is spinning. Nissan has a safety bypass that doesn't allow left foot braking, is that what you mean? The VDC doesn't turn itself back on.

No, ABLS remains on.

I dont know what to think.....but I can tell you I never hit the brakes when this happened to me yesterday. Anyway, tonight I made a u turn and got on it some and caught a nice fish tail and no VDC engaged at all! I was a little less agressive tonight with my girl in the car though, but still got sideways a bit and no net!!

Read your owner's manual

The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator illuminates
to indicate the VDC system is off. When the
VDC switch is used to turn off the system, the
VDC system still operates to prevent one drive
wheel from slipping by transferring power to a
non slipping drive wheel.The VDC warning light
flashes if this occurs. All other VDC
functions are off, and the VDC warning light
will not flash. The VDC system is automatically
reset to on when the ignition switch is
placed in the off position then back

You were doing a one wheel retarded burnout

What Cossie says or if you accidentally brushed the brake pedal and switch is not properly aligned. You may have triggered brake sensor switch that will put car in limp mode.

:iagree:

You triggered ABLS. Excessive inside wheelspin or even excessive rear wheelspin relative to the front wheels will active it and pulse the rear brakes momentarily. It can be disabled by unplugging the module under the center console near the e-brake.

I leave it alone, it almost never interferes with what I am doing and to trigger it on the street you have to drive like a maniac.

There are plenty of other threads about this. I can spin the tires at will in a straight line, doing doughnuts, drifting corners, ect., with the VDC off. With VDC off you can do what you want with the rear tires as far as throttle goes.

To clarify my point, the ABS system will reengage some form of VDC if you're out of control and apply the brakes. I was sliding 90deg sideways on the track at 70mph and had full opposite lock dialed in. The car wasn't doing what I wanted, but as soon as I applied the brakes she did the VDC shimmy and went right where I was trying to point her.

A second instance happened at my autocross last week. The fastest part of the course was a fast 'straight' that was actually a slight arc. I'd touch 60mph and then be hard on the brakes while still turning through the arc to then enter a hairpin. On one run, the car was very unsettled as I rolled hard into the brakes and the VDC did the stabilizing shimmy despite being turned off.

thats ebd, electronic brake distribution. technically its not part of the vdc traditionally speaking, its just your abs slowing your car
