Quick questions about the ATTESA-ETS on my G37X
I got the basics of how the system performs.
Lets concentrate on the right vs. left wheels on both axles.
Rear Axle: The system uses Active Brake Limited Slip (ABLS) to transfer power between the left and rear wheels?
Front Axle: Viscous Limited Slip Differential to transfer power between the left and rear wheels...if power is being sent to the front?
I understand that the system is 0 Front/100 Rear unless slip is detected.
Yes/No?

Sorry...it was late...lol. Yes I mean Left and RIGHT wheels. Hehehe.
Ok, more questions.
My car was "broken" for a few weeks so my VDC OFF and SLIP lights were constantly on.
According to the dealer and my own experience...my X was a 2wd ONLY car. They were right. I spun the rears like a mustang...but it was an accident..to much gas on a wet road, trying to merge onto another road.
SO my car fixed now, all systems normal:
1. If I manually turn the VDC off, my car remains an AWD car...right?
2. Turning the VDC off will turn off the skid control (think winding road), but how about the traction control aspect of VDC. Meaning, if I was on an ice rink, with VDC off and I hit the gas, would all 4 wheels spin very fast?
With my altima, TCS ON made it impossible to spin the wheels in snow/slush. It worked very well.
Guess I'm just wondering what VDC off would do?

What exactly did the dealer say was wrong with your G? My RWD '09 G37s has the same two lights popping up on the dash. I have an appointment to take it in on Thursday for that, to reset my TPMS sensors, and an oil change before it gets put away for the winter.

Yes, if you turn off VDC, your car is still remains in AWD. In fact, Nissan "recommends" if you are stuck, you should turn off VDC to spin the wheels to get free. This is exactly what Nissan's head engineer for the GT-R says. He says that is the only reason VDC should ever be turned off with ATTESA E-TS equipped cars.
The 4-wheel ABLS system and ABS will still operate with the VDC system off. On ice with VDC off, you will spin all 4 wheels. For 4-ABLS to work, there needs to be at least some small amount of resistance on one of the 4 wheels.

2. VDC affects yaw control (think of spinning out at the racetrack) and as such, also monitors traction at all four corners. Turning it off would allow some tire spin on slippery surfaces.
TCS has a more limited role than VDC and is engineered differently for, say an Altima, than a G. Turning it off allows greater slip angles and tire spin, on any surface.

No no...my car was broken. Without causing a fight here, I did some rewiring and fried some fuses. The result was a constant VDC off and slip lights BOTH on steady. This is totally different than me/one just turning off the vdc.
My car was malfunctioning..SO...the G37x...was X no more...LOL.
BUT my car is fixed now..thanks a nice dealership.
BTW: Thank you GT-R, you answered my question about the VDC.
