Turning off the trac control...

I've drifted wet corners above 50 mph with trac off light, I think it works a little different for various years because I could never shut it all the way off in my 09

 

I guess the traction control in the Tacoma isn't very good then. My rear wheels slip with no intervention at all when I am in rainy conditions.

 

Does the AUTO LSD light go out ?

 

actually ABS modulates the brakes so that you can steer while under full braking

 

Yeah. The LSD goes out. Id have to look at it again to see which other lights go out or come on. I can't remember at the moment.

It's different lights than the 2011 that I had. Plus it doesn't make the beeping noise when it gets squirrelly like the 2011 did.

 

One quick push.





Long push.

 

ABS increases stopping distances on low traction surfaces like snow

 

Wait a minute Oz I want to make sure I've got this right. It increases stopping distances or decreases stopping distances?

 

Increases when you are on slippery surfaces as it will not allow lockup which can help with snow as it will then buildup in front of the tires and help you to stop.

 

Increases

 

lol so well put in such few words

 

No

 

OZ, use this post of mine instead... it is clutter free and has photos of the dash lights at the start:

2012+ has TRAC OFF in H4 (which is the same as TRAC in H4 in 2009-2011).
2012+ TRAC in H4 has engine regulation (like H2 TRAC does).

To the OP, keep in mind, Toyota doesn't want you to wreck your truck and then say it is Toyota's fault (like when 2 or more floor mats are under the gas pedal)... So, the nanny systems are to keep your nice truck from being destroyed and you hurt.

Being able to turn off the VSC and TRAC so just one rear tire will spin is to allow you to fling out the mud and snow so you can get out if TRAC and AUTO LSD couldn't.

STOP MOVING, PRESS and HOLD the VSC button... Toyota says it's 3 seconds... but I must count fast, so I say 3-5 seconds. Then drive without any traction control or VSC. VSC will come back on if the computer thinks you are close to rolling your truck. VSC is the biggest contribution to auto safety since the seat belt, so they say.

HERE are the changes made in 2012+:

The Buttons do what? A discussion with simple answers to what the (up to) 10 drive modes some models have and how to use them.

Limited Slip systems called TRAC, AUTO LSD, TRAC OFF and A-TRAC use engine output regulation and/or brake force to a non-traction (spinning) tire to transfer drive power to tires that have traction and can move you ahead.
Some are automatic and others require a selection to have greater traction control or no traction control.

The newer 2012+ term TRAC OFF in H4, is the same degree of control as what was called TRAC (in H4) in 2009. TRAC in 2012 became an engine output regulated traction control in H4, as it is in H2.

2009-2011:

Press Nothing...

H2= TRAC (Limited Slip with Engine Output Regulation)
H4= TRAC (Limited Slip without Engine Regulation, front and rear)
L4= No Traction Control
-----------------------------------------------------------------------------------------
Quick Press (VSC OFF SWITCH) moving or stopped...

H2= AUTO LSD (Limited Slip without Engine Output Regulation, VSC OFF to 30 mph)
----------------------------------------------------------------------------------------
Press and Hold In 3-5 seconds (VSC OFF SWITCH) while stopped...
H2= VSC OFF (No Traction Control)
H4= VSC OFF (No Traction Control)
----------------------------------------------------------------------------------------
Off Road TRD:

Quick Press of RR Lock Switch= Rear differential Locker (L4 only on 4WD models)
L4 Only: Quick Press of A-TRAC Switch= Front and Rear near-no slip traction control. A-TRAC works the front tires if speed drops below 3 mph, if the Rear Locker is also on.
======================================================================

2012 + (chages in bold)


Press Nothing...

H2= TRAC (Limited Slip with Engine Output Regulation)
H4= TRAC (Limited Slip with Engine Output Regulation, front and rear)
L4= No Traction Control
---------------------------------------------------------------------------------------
Quick Press (VSC OFF SWITCH) moving or stopped...

H2= AUTO LSD (Limited Slip without Engine Output Regulation, VSC OFF to 30 mph)
H4= TRAC OFF (Limited Slip without Engine Output Regulation)
---------------------------------------------------------------------------------------
Press and Hold In 3-5 seconds (VSC OFF SWITCH) while stopped...
H2= VSC OFF (No Traction Control)
H4= VSC OFF (No Traction Control)
---------------------------------------------------------------------------------------
Off Road TRD:

Quick Press of RR Lock Switch= Rear differential Locker (L4 only on 4WD models)
L4 Only: Quick Press of A-TRAC Switch= Front and Rear near-no slip traction control. A-TRAC works the front below 3 mph when the Rear Locker is also on.
==========================================================================

What should you use?
Standard Mode until you lose traction, then quickly press the VSC OFF button to increase the power of your traction control (more engine RPM, stronger braking on the spinning tires).

In L4 (Low Range) and your tires spin, press the A-TRAC button (Off Road TRD only) to nearly lock-up any spin. I always have A-TRAC on in L4... unless you need to spin the mud out of the tires.

Emergency stuck if A-TRAC doesn't work in any situation, press the RR Lock button (works with or without A-TRAC working on the front tires). The rear locker connects both rear tires from inside the differential (0 spin). Turn off RR Locker, once you are unstuck.

1) H2 TRAC

3) H2 VSC OFF
4) H4 TRAC
5) H4 TRAC OFF
6) H4 VSC OFF
7) L4 VSC OFF
8) L4 & A-TRAC
9) L4 & Rear Locker
10) L4 & Rear Locker & A-TRAC
