Auto LSD on with Trac off?

there are no wires to cut anymore, that's the problem.

 

OK, so, in 4HI, how do I stop it from cutting engine output to control wheel spin on a MT OR model? If I press the traction control button (not A trac button) I get a light on the dash but it still won't let it spin even if I'm making progress. It is extremely irritating when going up steeps in the snow or just screwing around.

So, long/short: I want 4WD with traction but not ANY interference with my throttle inputs.

 

TRAC OFF

 

So, stop, press and hold the button? But that turns off all the brake actuation/eDiffs too, right, so I get a one wheel wonder?

 

I read this thread, re-read this thread, and I'm still confused. what do I use if i'd like to haul ass on a open dirt road and maybe drift a corner or play in the snow and not have the truck sound like a cheese grater when the ABS or whatever the hell it is fires?

 

No, one press of the button will get you into TRAC OFF if you are in 4HI

You need to stop the vehicle and then press and hold the traction control button until you see two new lights appear on the dash. It takes a long hold to get it to go into NO traction control mode. I don't actually know the name of this mode....

 

Guys, spinning is lack of traction.
The goal is to climb the hill without losing traction or spinning any tires.

Quick press button is TRAC OFF. This is unregulated output and braking only for max power to move... but not spin!

Stop and hold in button 3 sec. to disable TRAC, so open differntials only... TRAC turned off. Max tire spin, damage the trail and maybe your truck!?

The advantage of 4WD is you can crawl slowly and save your parts from damage. 2WD needs momentum to climb, but not 4WD typically.

 

Thanks! ok, I've done that and have intermittent success. At higher speeds does it re-engage? And i'm assuming there is nothing you can do about ABS?

 

Trac Off turns off at 30mph

 

In 4HI, in my truck (MT/OR) with one push of the button the icon of the truck with the squiggly lines goes on/off at 30MPH and one other light stays lit all the time. I'll have to confirm if it's AUTO LSD or TRAC. They are both in the same location and it was snowing like a mofo so I was busy trying to see past the end of the hood.

 

As I have posted, Auto LSD is ON with the button pushed, in H2. The VSC OFF light (truck with squiggly lines) also goes on to 30 mph, then goes off. VSC is a driving control to keep you moving straight if the truck begins to slide sideways.

Auto LSD is on standby with the light on, like TRAC and the other modes... they await their being needed. AUTO LSD is to get you moving from a stop, like when one tire is on ice and wants to spin. At 55 mph, there is no need for any brake assisted traction since you are not stuck, or at a stop light, or parking spot.

Again:
TRAC, AUTO LSD, TRAC OFF are traction systems to get you moving from a stop. They only activate if a tire begins to spin differently than the others, like when you hit the gas at a stop to move, or when you slide around when four wheeling in soft stuff. A beep-beep-beep will be heard and the TRAC light will flash when there is traction loss and the system is working.

VSC is a stability system to keep you going in the direction you intend. This is a moving, like highway speed system... but works at slower speed if you begin to slide. It is a great system and is only improved by 4WD. The truck in 2WD with VSC in rainy weather handles like my older truck in 4WD on slick roads did.

 

IF you are in VSC OFF, you don't have TRAC or VSC UNLESS you drive in a dangerous manner, then VSC will come on to prevent you from wrecking (or try to anyway). DON'T USE VSC OFF MODE! I see no reason to not use the great drive systems they have invented. If you want a truck to slip and slide around, buy an old junker or at least pre-2009.

 

So, all I really want is to turn off only the cutoff/out of engine power in response to wheel slippage and leave the passive stuff on. Previous posts and my take on the owners manual have indicated just pressing the button once will do it but, that does not seem to be the case - at say 10MPH while trying to get the rear loose with throttle to sharpen a turn in the snow it cut throttle and flashed the VSC light. Holding it disables everything - which then won't use the brakes to simulate LSD (eDiff or whatever Toyota calls it) and move power to the other wheel. So, maybe what I want isn't available? "Fun Mode".

 

I don't know what you think the braking (slowing/stopping) the truck has to do with the traction system (designed for moving/ going)... ?
My truck AUTO LSD stays on until I press the button or restart the truck.

 

A quick button press (AUTO LSD/TRAC OFF) gives you the most traction (braking of a spinning tire) without the engine power being cut.

Let me add: The title of this thread is confusing because AUTO LSD and TRAC OFF are the same thing. One is 2WD and the other is 4WD being the difference. In 2009, before the TRAC OFF button was needed for H4, they actually say TRAC OFF is AUTO LSD ON.

 

Good thread.. Confusing for a first time taco owner but good info. Thx.

 

Seriously right!???
Calling more or stronger TRAC, "TRAC OFF" has got to be the worst blunder.
AUTO LSD when there is no differential involved is pretty bad too!
TRAC MAX would be a better name than TRAC OFF and AUTO LSD.

 

This is the questionable one. According to what David has been saying just pressing the button once and going into Auto LSD mode should in theory let you rip mad two wheel drifts but you arent the first person ive heard say it doesnt actually let you do it. I think the very same thing happened to OP and thats why he made this thread.

Auto LSD mode has no engine regulation but brakes spinning wheels so why arent people able get full on two wheel drifts/burnouts/whatever going? Maybe VSC detects "dangerous driving" and cuts in.

 

Perhaps?
In any case, what they are trying to do is not what Toyota wants to happen and then have lawsuits filed because somebody's kid died in a "dangerous Tacoma" roll over.
The truck is awesome, use it as it was made to be used, not spin donuts and drift, etc.
The truck will outdrive off road any other truck. The level of quality it has and value it holds is superior.
Have fun with the truck by going for drives, camping, off-road challenges, but don't see if you can roll it over by driving like a nut. It will just ruin it for the rest of us by adding more restrictions on how the truck will perform. I am sure the rear locker will be discontinued the way some of you are using it on the highway, etc.
Have fun, it is a great (and expensive) TOY, but don't trash it even if your daddy bought it for you!

 

Not sure if mentioned yet, but if you have VSC off or Trac off you cannot engage cruise control.
