Nissan 370Z Forum - View Single Post - Hello from sunny North Carolina -- 370Z Traction control vs VDC issue

My understanding is that VDC encompasses TC. In other words, VDC is like TC and then some. You won't find a Nissan with separate VDC Off and TCS Off buttons -- it's one or the other. If you have VDC, you automatically have TC, but the reverse isn't true. i.e., it is possible to have TC only and no VDC, but not the other way around -- which makes sense as VDC is electronic stability control. For the record, Joey, I own the car too. I own a Touring model, and I do have the Sport Pkg, and can tell you that there is no separate TCS Off button -- just the VDC Off button. So your assertion that you can turn off TCS if you have the Sport Pkg isn't quite on the mark. Also, I referred back to the manual from my 350Z and found the following statement in the VDC section: "If the vehicle is operated with the VDC system turned off, all VDC system functions and TCS functions will be turned off." This goes to what I'm saying about VDC including TCS. Now, the interesting thing is that this verbiage is not present in the 370's manual. And that actually makes sense if all 370s come with VDC and none of them come with TCS only (my 350 came with TCS only). There's no need to differentiate between the two systems in the 370 as all 370s come with just the one. But the manual does also have this verbiage: "The ABLS system and ABS will still operate with the VDC system off." And prior to this sentence, it explains that ABLS brakes the spinning wheel when there's wheel slip.

SO . . . the net of this is that you're both right and wrong. You're wrong when you say that there's no button to turn off traction control in your car. Yes there is -- it's the VDC Off button. And as I previously stated, I have the Sport Pkg, and there's no separate TCS Off switch. The VDC Off button is it -- it's all we get regardless of trim line. But at the same time, you're right about there being no way to truly turn off traction control, because the manual comes right out and tells us that even with VDC off, the ABLS system still operates! And I agree with you -- that's really annoying! What's the point of having the VDC Off button if you can't ever truly turn the nanny off? But if it makes you feel any better, having the Sport Pkg doesn't change this. So you're not missing out on anything.
