How to completely disable the VDC

Hi-Step'n370Z · 03-18-2010, 07:21 AM

To all who want to know how to disable the VDC. While searching all over the web, I stumbled onto this bit if information. Hope it helps those who are interested.

"If you use the factory switch, the VDC only partially turns off. If you want to completely disable it, you have to disconnect power to the yaw sensor."

Yeah, but we haven't had a good "I crashed my Z, friend turned off the VDC" story in a few weeks...

If my car only has it partially turne doff I don't want it all the way turned off. The Z get's sideway's enough already.

When it's off it only limits wheelspin, doesn't prevent you from doing a 360 pirouette in front of the oncoming semi-trailer.

my VDC is odd

if its on and I floor it the tires squeel and the back end tends to step out

I tried turning it off once.

floored it. ZERO tire noise. ZERO wonky back end.

odd car mine is

That is interesting info, what part is still running when it partly off?

Hi-Step'n370Z · 03-18-2010, 08:01 AM

I like the VDC too, glad I have it.

As far as what is still running when it's off, or partially off.......I haven't a clue.

I posted the "how to disable" info because I remember some on the Forum were wondering if it could be done, and if so, how.

I have no plans to disable mine.

If it is off, it is off.
I believe in a past thread someone found VDC to be 100% off, but something else is still on (ALBS or something, will find later today).

Some info I found on "another Z site" (I cannot vouch for it's accuracy, but appears to be how I understand it to work):

Quote:

TCS compares wheel rotation and cut throttle to stop spinning. The more aggressively you spin the tires, the longer it takes for throttle control to return. Lite spins may not even be detected so it is still possible to slide the back end in some cases. When it is turned off, it is off.

VDC includes TCS and adds the yaw sensor and individual wheel braking for corrections. When using the factory switch, VDC only partially turns off, to completely disable it, it is necessary to disconnect power to the yaw sensor.

Also the models with VDC also include BLSD, or brake limited slip differential. Brakes are used to compensate for slipping rear wheels when the VLSD is overpowered or not coming in quick enough. Nissan does not consider this part off the VDC system.

And here's a GREAT link I found to Nissan's Explanation of what VDC is and how it works:

The ABLS system brakes the spinning wheel, which distributes the driving power to the other drive wheel. If the vehicle is operated with the VDC OFF switch pushed and the VDC system turned off, all VDC systems will be turned off. The ABLS system and ABS will still operate with the VDC system off. If the ABLS system is activated, the (slip) indicator (light) will blink..."
