Sorry for the delay, we had some unexpected occurrences to deal with out of town. The pumps associated with the entire Vehicle Stability Control System and/or the stabilatrack system went out leaving the system engaged which is preventing my truck from shifting properly. It feels like the brakes are being applied when I try to accelerate. All I want to know is how to completely and entirely disable the VSC system and all of its components. I live in Louisiana, it is not useful to me. Is there a relay I can pull and fuse I can pull or anything along those lines that will allow me to disable or totally bypass the VSC system?

yes there is but I too have to go out right now but can have your answer latter today if that's ok or do you want me to pass it on to another expert? It's your choice.

VSC Off…Doesn’t Turn VSC Off

For 2007 Toyota Tundras, pushing the VSC Off switch a single time doesn’t actually turn off Vehicle Stability Control. As confusing as it sounds, VSC remains active, but TRAC is turned off and in its place comes Auto LSD. Toyota added this mode in order to allow for full power application while still minimizing wheel spin through the Auto LSD feature. In order to fully disable all three systems in the 2007 Tundra, you have to actually have the truck completely stopped and then push and hold the VSC Off switch for three seconds.

2008 Adds An Additional Step

2008 and up Tundra owners were given an additional driving mode that slides in between 2007’s number two and number three. Holding down the VSC Off switch in these trucks turns off VSC and TRAC but keeps Auto LSD active, which can be useful when heading off-road or when dealing with deeper snow. In order to switch off all three, you will have to push and hold the switch for an additional three seconds – again while the truck is stopped.

Four-Wheel Drive Differences

When four-wheel drive is engaged – specifically 4H – the process for disabling Vehicle Stability Control is somewhat different. To turn off TRAC, simply push the VSC Off switch once. To turn off both TRAC and VSC, stop the vehicle (not difficult, since you are probably already stuck at this point) and then hold the switch for three seconds total. In 4L mode, you only have the option of TRAC off, which means that you have to hold the VSC Off switch for three seconds right from the start.

Needless to say, the systems each automatically re-engage once the vehicle has been turned on and off again.

Consult Your Manual

Confusing, isn’t it? This information is buried deep within your Tundra’s manual if you are looking for model year-specific information about how your VSC system interacts with your pickup. The instructions above, however, should help you get out of whatever sticky situation Toyota’s electronic driving aides might have gotten you into.

I have read the manual cover -to-cover. I tried this already; not what I am looking for. I want to completely disable the entire aforementioned system(s) so that it cannot re-engage and it becomes a non-factor.

here is a video as well. If this is not to your liking you may have an ABS problem as well and then you may have to pull the ABS relay , THIS MAY TURN ON SOME TROUBLE TIGHTS BECAUSE THE REST OF THE SYSTEM IS STILL HOOKED UP TO THE ecu Hope thiis solves your problem . The other option is to find a cheaper ABS module either used or online they are ralitivaly easy to replace and you don't have to bleed anything.
