How to Disable Traction Control and VSC

I ran across the following in Automobile Mag and wondered if it also worked on the 2006 RAV4 :D

After being continually frustrated with our inability to completely turn off the GSÃ¢â‚¬â„¢s traction and stability control system, we recently learned from an anonymous source how to disable the overprotective electro-nanny. Road test coordinator Marc Noordeloos performed the complicated procedure, took a test drive, and, while grinning from ear to ear, pronounced the car transformed. If you own a 2006 GS (or IS), follow these steps and enjoy the slide. Once the car is started, you have thirty seconds to complete the process. With practice, the procedure can be completed in approximately fifteen seconds but, unfortunately, must be repeated each time the car is switched off.

1. Make sure the car is in Park and the parking brake is disengaged before you start the car.
2. Start the engine.
3. Engage the parking brake.
4. Fully depress the brake pedal and then release.
5. Fully depress the brake pedal and then release.
6. Disengage the parking brake.
7. Fully depress and hold down the brake pedal.
8. Engage the parking brake, then disengage it (while holding down the brake pedal).
9. Engage the parking brake, then disengage it (while holding down the brake pedal).
10. Release the brake pedal.
11. Engage the parking brake.
12. Fully depress the brake pedal and then release.
13. Fully depress the brake pedal and then release.

When “Check VSC" is displayed in the multifunction display along with the “Trac-off" icon indicator, you'll know that you have successfully completed the procedure.

Anybody want to try it out?

thats sounds like a cruel joke Kelly! after you go thru all that and it does work.. how do you make it active again??

considering how vsc functions as LSD for 4WD, I really see no point in disabling it. Plus, I tried to drive it hard during rain and I never heard any complains from VSC, despite adding lots of power on twisty mountain roads during rain.

Like Kelly's excerpt says, this sort of override for the stability control is only temporary until you turn off the engine. The next time you start out it's back on again. I can see wanting to turn it off occasionally when you want to have some fun.

Anyone have a wiring diagram? All you need to do is interrupt the road speed signal to the computer that controls the center diff lockup. Install a SPST switch and open that circuit and the system "should" stay engaged regardless of vehicle speed.

I haven't tried this, so take this advice with a grain of salt.

Anyone want to experiment?

why would you leave it on? I suggest you drive it a bit and decide if you really need an switch or not. System works perfectly and a lot more than what you would think.

I tried this on my RAV today on my way home from work and it works. Follow the procedure and it will turn off VSC until the car is turned off. I didn't notice any difference driving, but I'm still breaking it in, so I'm not driving it hard at all. I'm sure it will be fun to do someday though just to see how different it acts.

Thanks for posting this, its works great! It is something that I have wanted to be able to do since I upgraded from my gocart like 4.1. but had given up all hope. I suggest that this be posted in the mods section.

hey,

I saw this post, and the complexity involved in disabling the traction control...

I did a lot of research on the VSC ecu & system and came up with a way to disable it,

although its on a Caldina GTT not a RAV4, they are both 4wd toyotas right? so it may be worth testing it out...

A bit easier than the process you have listed there!!
