I have done this

I don't know about the exhaust, but I can tell you how to clear the VSC.

read this service bulletin: You can clear the VSC light . Page 8 tells you how to do it without special tools. alflash.com.ua/tsb/ZERO%20POINT%20CALIBRATION.pdf

A diagram on this post will help you find the correct terminals to short:

Did that work for you?

 

Sorry, the link to the tsb isn't working right. You should be able to copy and paste the address into your browser.

Yes, I have done this several times and it works on my highlander.

 

My VSC light is on after changing air filter on 06 Highlander? Any ideas or clue would be great? Thanks

My VSC and CEL came on after changing the battery (posted a question about it yesterday).

Seems like something that happens rather often, but for random reasons. I don't know what I could have done by changing the battery.

 

The VSC light on my wife's 2004 Highlander with 100K is flashing on and off. The flashing is about once or twice per 30 mins. When it comes on the brakes get activated. We are not skipping when the light comes on. The CEL is not on.

Is this something that I can fix myself. I have an OBD reader. I am totally guessing that there is a a faulty sensor or traction computer. Sounds like an expensive trip to the dealer!

 

First, pull off each wheel and take a look at the sensor. Make sure it is screwed all the way in. They can work themselves loose and then don't count the full number of revolutions the wheel is making. If it's front wheel drive, I'd assume it's one of your rears from what you describe.

Also, check under the front pass seat, I'd undo and reconnect all the cables down there. One may have been loosened and causing problems.

What does the sensor look like? Our car is front wheel drive so I can pull off the rear wheels. Just to know what I am looking for.

thanks,

There is only one electrical wire running to the hub, and a much thicker brake line. When you take a wheel off it will be obvious what you are looking for. You might even be able to get a decent look without removing the wheel.

 

I had this same problem. It turned out to be a YAW sensor needed to be calibrated. I was lucky my buddy had a snap-on model tester that could read all the codes for the different systems in the highlander at his garage. He did the calibration of the YAW sensor and light cleared.

 

Update. I've been driving the Highlander a few months with VSC on, but had it to import service place today for some stuff. He recalibratred YAW but came right back on. He believes YAW sensor needs to be replaced and I told him to order it.

Said I had to clean the junk pile I have in the back, I guess that sensor is under rear seat!:facepalm:

Please let us know how that works out. Mine comes on about onec a month now so I guess I'll need to do the same thing. Any idea how much it will cost? Ask for the old part and post a photo if you can.

 

I never replied as I promised, and I apologize. For future reference.

Thanks. Replacing it did the trick for you? I'm still needing to change it.

 

My experience with the VSC light illuminating after I replaced the air filter was due to me inadvertently disconnecting a vacuum hose from the air box on the side that faces the firewall. There isn't much slack on that hose and I do it almost every time I change the filter. I thought about investing in a hose clamp, but that's just one more thing I'd have to loosen when it comes time to change the air filter :lol:.

My issue might be unrelated, but could be the culprit for some.

 

YAW Sensor ??? Where is it? What is it ??? Hmmm

 

What is it ???

detects rotation of car (along the plane of the floor pan, so left/right rotation). Its used by a whole lot of systems to work correctly (TRAC, VSC, SRS, others)

 

Have you priced these?

I've been looking for one for a while. they run right under $300 on the web, a little too rich for experimenting on my budget. I keep resetting it and it comes back on every once in a while with my check engine light but won't always go out when I reset the CEL. I've had this issue for about 5 years now and am getting ready to sell the highlander, so I'd like to get it fixed.
