PLEASE HELP, SOMEONE, ANYONE! I have a 2004 AWD Rav4 168,000 miles. I am having a major issue with the Traction control VSC ABS system. It started off by beeping around slight turns in the road. Eventually it became more and more sensitive to the point where it actually engages my traction control and "breaks" my car automatically around the smallest turns on the highway. It is becoming more and more dangerous to drive as I don't don't when the car is going to suddenly break on me. My car has a missing switch to turn off the traction control and my mechanic says I should purchase a new switch so that he can determine what the codes give off when hooked to the computer. Has anyone else experienced this before? Is it a problem with my tires? or could it be a faulty traction control sensor? or could it be this missing switch that is causing the signal to engage the traction control??? I'm at a point where I HATE drving the car because it's getting dangerous on the highway.

I don't have a 4.2 so I can't advise you but I'm bringing this to the top so possibly someone else can comment.
I do know that my 4.3 doesn't have a switch to turn off TRAC either and there is no way of connecting one from a later model that does have one.

I have a 4.2 European/ UK spec.
There is no VCS only EBD. And two variants have LSD but no switches for either

It could be the rear diff and LSD are malfunctioning which can cause the tail to slide wide.

Of course US version could be different

Well the VSC is controlled by the Wheel Speed Sensors (same ones that work the ABS) to detect slippage. But before going and looking at these, I would absolutely follow your mechanics advice.

You are having a VSC problem and have an obvious fault to begin with (Switch is bad). Why on earth would you not have this fixed when you know there is an issue with this system. It is sort of like saying my grass is not growing, I know I have not been watering it but I am wondering if the soil does not have enough nutrients or if I have some sort of insect infestation causing the issue.

Start with the obvious and then work your way through.

I have an 05 Rav4 with 170k miles and I'm having the same issue. I've taken it to my tire specialist, 2 mechanics and there is nothing but guesses. One mechanic plugged it to the code diagnosis thingy and nothing came up. They also said it probably needs new struts and barrings but the other mechanic said "it does not, it's probably electrical" and take it to the dealer since they are specialist. -_-
I do have the traction on and off button but it does NOT solve the issue. It helps a tiny bit but it still comes on and beeps/brakes dangerously at me on the freeway. Anyone have any suggestions? I have a feeling the dealer will take my $110 and not be accurate.?

A shot in the dark ay the most obvious. Are all 4 tires the same size and make? Oh and pressures all the same too.

Same issue here; It started a few months ago. There's one off-ramp that always activates the Skid Control feature and applies braking to one wheel. I filed a complaint on NHTSA but haven't heard anything back.
I read somewhere it could be related to steering rack bushings but that's a crap shoot.
All 4 tires are same make and spec and tire pressure is 29psi.

The only time I have had my VSC/TRAC beep was when the rav is fully loaded down in the back and I punch it to take off on wet pavement. I guess the front starts to lose traction and maybe spin out. I have not had it do that in curves though. It is also a 2004/05 German spec'd version.

Codes I read a few months back. They haven't returned since I cleared them but the VSC still kicks in from time to time while taking sweeping right turns.

seems like your problems are directly linked to the either abs module faulty or a bad abs sensor/wiring or maybe all three. Some vehicles tell you specifically which sensor is at fault depending on the fault code reader you use and some don't so you have to change each one with a new one until you find out which one is at fault. either way its most likely electrical related and first thing you do is buy a new switch like the mechanic asked you to do as we cant give you a magic potion here in the face of good local advice on the switch, not heeding your mechanics advice makes you possibly as dangerous as the car.

Can somebody please help. I've got a RAV 4 2004 and my wheels are spinning when I have to stop-start. We've got a lot of rain in South Africa and I'm scared I'll drive into somebody.

I was having the same issue. Had to go to a Toyota Dealership which I hate because these new mechanics know hardly anything about these things in my opinion. Took 3 trips there to finally threaten them with a lawsuit because they never test drove the car to begin with when they gave it back saying it was fixed and it wasn't. Make sure you have a MASTER MECHANIC take a look at it & test drive it with you. They all trouble shoot things, waste of money but sometimes that's what you have to do. After the MASTER MECHANIC test drove it & actually lifted it up on a lift to look at the undercarriage unlike the first idiot/lazy mechanic, found that I needed a new rack & pinion becaise it was loose and worn, which isn't what I wanted to hear but it ended up FIXING the issue. If the steering is off it will throw of the traction control sensor which causes it to act that way; constantly beeping, breaking by itself on uneven turns like on ramps & off ramps, etc. They ended up giving me a BIG break because of a possible legal issue and it only cost me $360 to fix but normally depending if you have a hook up or a mechanic you can trust, it can cost $1000 or more to have it fixed.

Yep, steering box, etc. Had to get a new Rack&Pinion in order to fix my issue. What was the outcome?

I ended up cleaning my 2 front speed sensors which helped somewhat. The issue has only occurred once since. I have poly steering bushings but haven't had time to swap them in.
