In the 2004-2006 models the "Trac Off" button does not disable VSC (stability control) like it did in previous models. Holding it for more than 3 seconds does not shut it off either, like it does in the newer models. Is there anyway to properly shut it off? I tried looking at older posts but old news. Checking to see if anyone has found a solution.

 

Pull the VSC sensor connector off, just make the system go into failure mode.

 

And where is this connector located?

 

Pick any of them, just disconnect something related to traction control or vehicle yaw. Look up where the yaw sensor is and unplug it

You may need to use Google if your browser doesn't translate it from Japanese for you.
To re-enable VSC/TRC you need to switch it back on with the switch, and then turn off the car before restarting it.
