As far as I know, there is no traction, nor stability control on NM/PNM35s.

You have the awd system, which actively shifts torque front and rear, but there is no individual wheel interaction besides the abs system.

Pm35 models (rwd) have traction control only.

So... What did you cut?

What I did was install a switch between the ground line to the yaw sensor/ g sensor. After doing this it feels as the car is rear wheel drive and when it brakes traction the Ecuador des not retard the engine and drop the revs to regain traction you can just keep lighting the tyres up. When the switch is on the 4wd and abs lights come on but abs is still working. Look up 350z VDC off and g35x turn off VDC. Same principleas ours http://my350z.com/forum/engine-drivetrain-and-forced-induction-diy/505135-diy-disabling-vdc.html our VDC looks like this in this pic.

You mean it doesn't transfer power to the front, it stays RWD, as would be expected when you cut the G sensor.

Our engines don't retard or drop revs afaik. The V35 does, and it has the TCS light on the dash too.

Yeah it seems to be. But it also didn't seem to drop the revs when traction is lost. As in when I plant it from a stand still up my hill it looses traction then revs drop till it is regained. After disabling the g sensor via a switch I can just keep the tyres spinning all the way up the hill.

Your right that it defiantly isn't the same as in the 350z and v35 but still some benefit from adding the switch:)

At a guess, it drops rev because the starts sending torque to the front, and starts to create more grip. Now you have just made a rwd. Dunno if it's safe for the awd system or not.

Just for any pnm35 owners looking, all you have to do to make yours rwd safely is remove the fuse in the drivers kick panel.

I looked into this with my Nissan mech mate, seems there are two Attessa computers at least, one of which probably has some traction/stability control. His is an ARX, mine a base model RS and they are different part numbers.

I know Craigs ARX never had traction, or stability control. :P

well been driving with it switched off in red mode for the past few days. Seems to be no issues with the Atessa system as it will re engage with no issues when switched off and restarted. So so far seems to be a simple way to alter between awd and RWD ;)

That's good.

But what I really meant was there maybe pressure causing damage to the transfer case. I know there is some difference between the systems in the r32 and the 33/34 which means you can flick a switch in the 32, but in later models you can install a switch, but it causes damage to the transfer.

I don't know enough about the clutch packs and pressure to tell you exactly the issue, but I know some cars are effected. Just want to make you aware of it.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
