VSC, Trailer Sway Control

All I can tell you is that Toyota says it is off when disengaged. If is still engages and causes a safety issue it needs to be reported.

 

Can you post this law you are talking about? According to Toyota when disengaged it is off. As for lift Toyota allows for a 3 inch lift before warranty is affected.

Always ON bro on any vehicle below 10 000 LB
Unless you driving Offroad registered vehicle (Polaris Razr, ATV etc)
and no no lift on those vehicles is allowed.

 

Thank you for the article. Yes but that does not say it cannot be turned off. It only says it has to be equipped. That article also covers ABS which is mandated and the ABS can also be turned off at least on my truck. I will contact Toyota corp. and see what they say. I will let you know if they respond.

 

Its has to be Always-ON unless vehicle has exception.
Do you have a exception for your vehicle model?
Try it but its in the software running on your system, unless you pull the fuse it will be always on.
You have ABS switch ? Or you talkign about ABS Off when you engage locker?

 

Here is what the book says.
Trailer Sway Control (vehicles with towing hitch and 7 pin

connector)



Helps the driver to control trailer sway by selectively applying brake

pressure for individual wheels and reducing engine torque when trailer

sway is detected.

Trailer Sway Control is part of the VSC system and will not operate if

VSC is turned off or experiences a malfunction.

 

VSC is ESC but not all ESC is VSC, just like all thumbs are fingers but not all fingers are thumbs.

 

AGREED! Off is OFF!

 

Not entirely true

 

Anyways

OP , as I said before , have the dealership do the VSC zero point calibration shown in the pdf file contained in the first post of this thread

Hopefully that works

If not , do the Landphil method ABS bypass mod I posted a link to earlier

Best of luck

 

Can you post a link where Toyota states that up to a 3" lift is acceptable as far as warranty issues are concerned

That would be some valuable information for the forum

I'll wait here

 

x2

 

My experiences have been 100% along the lines of what Oz has stated.

OP - will look forward to seeing what Toyota responds and says.

 

Still here

 

I agree....it is not totally off. I have been in the snow and had it engage when it was "off". Its never completely off.....period

 

Still waiting

 

I will let you know what they say. They acknowledged they got the email and now I am waiting on a response.

SubjectVSC Discussion Thread Response Via Email (Jay Spencer)08/29/2013 12:56 PMMr. Schumacher,

Thank you for contacting Toyota Motor Sales, U.S.A., Inc.

We appreciate the opportunity to address your inquiry regarding the operation of the vehicle stability control system (VSC) on your 2013 Tacoma.

When VSC is turned off, it is off. The VSC system helps prevent the vehicle from slipping sideways as a result of strong front wheel skid or strong rear wheel skid during cornering.

If we can be of further assistance, please utilize the following link to find a variety of avenues to contact our offices, http://www.toyota.com/support/contact.html.

Notice, OFF IS OFF!

For those who claim that theirs is still on but sensitive when turned off take it too the dealer and have it fixed as it is dangerous. Again OFF is OFF!

 

Sheez. That was a typical 'help desk' type of answer from Toyota. It is an interesting topic, OP.
