My 2001 Sienna, 86,000 miles, has been doing the same thing. Sounds like someone is kicking it underneath. Noise is loudest from driver rear side. I was thinking that it was New Orlean's bad streets having damaged something. The whole underside of my car sounds like it is going to rattle off now. I am diligent about getting my car serviced, so this has me thrown for a loop.
Will find out tomorrow from the dealership.

ABS Problem 2004 Sienna by bdkny2001
Feb 23, 2008 (9:31 am)

I own a 2004 Sienna with 70,000 miles. The ABS automatically engages when the vehicle is driving forward at more than 5 mph despite perfect driving conditions (dry ground, tire pressure). This is preceded by a beeping noise and VSC dashboard indicator. The Toyota service department has informed me that the ABS power unit needs to be replaced at a cost of nearly $3,000.
 
Has anyone else experienced this problem? Any suggestions as to other possible causes? It seems that all of my Toyota problems have been big ticket items. I trust that the dealer did it's due diligence.....?

Your Toyota service department appears to be out to lunch, or someone's child's college tuition is due.
 
There are only two sensors unique to VSC, the stearing wheel rotational position sensor the the yaw sensor. There is a procedure, a driving procedure, for recalibrating both. Have the dealer do both with you along as a passenger and if that doesn't work you either have a failed, failing, VSC sensor.
 
The VSC system is designed to detect when the vehicle is not following the direction set by the position of the stearing wheel. So the VSC system either "thinks" the vehicle is turning when it shouldn't be or isn't turning when it should.

Almost identical experience with 2004 Highlander recently. Had to drive car to dealer on back streets at 3-4 mph entire way or ABS would activate. Problem arose suddenly, no previous indicators that something might be wrong. In my case, dealer cleaned the VSC wheel sensors and recalibrated the computer for $380. There is a toyota bulletin BR008-04 cited on the repair ticket, but I don't know where to find details. Hope this helps you or others with this problem.

I had the same exact experience. I had a guy do the back brakes for me and when I got the van back the emergency brake went to the floor...the guy told be the cable needed to be replaced which I thought was odd since it wasn't to the floor before that and with new pads in the back it should have been even tighter. So I drove the van home and the brakes were very spongy and weren't stopping worth a darn. It was dangerous. I called the guy a few days later and told him the emergency brake wasn't holding and the van wasn't stopping even with the pedal to the floor. He said bring it back and he would check it out. He said the pedal going to the floor was probably the master cylinder so he replaced that and that didn't help one bit so I took it back to him and he said he would look at it. When I got the van back the emergency brake cable was magically fixed and the van stopped a whole lot better but I still couldn't get the van to stop quickly or enter a skid to where the ABS would start kicking in. I'm still having problems to this day. I'm orering some new Akebono Ceramic brake pads to see if that will help.
 
If anyone has any advice, it would be greatly appreciated.

Don't know if bdkny2001 ever read your post. Curious as to whether he paid $3,000 like the stealership quoted (appropriate term under these conditions), or the $300 gibson paid, per below your post.

2005 Sienna brakes pulse by khfvt
May 12, 2008 (6:01 am)

I have a 2005 AWD Sienna.
Last april the brakes started to pulse. When I slowed at highway speeds (as entering an exit ramp) there was a pulsing in the brake pedal. I brought it in and was told I had mud in the tires. They cleaned out the tires and things were better.
This spring I had a flat tire and when I brought it in for repair I was told that the rear brake pads were shot and it was "metal on metal." They replaced the pads.
I had not heard any warning squeal.
 
Now, a few weeks later, the pulse is back in the brake pedal. It mostly happens when slowing down on the highway. There is also a very faint whine when I accelerate at slow speeds, and I am not sure that is related.
 
Any thoughts?

Hi, I am new here. Just wondering if there's any update on this??? My wife's 2001 Toyota Sienna LE (120,000+ miles) has had this issue for a couple of months already and the technician couldn't figure out what's wrong with it. Thank you!

HI ,
I ahave the same problem with only one difference. When the car is drivin more than the 5 mph and the ABS start to apply the brake, only the slip light and a sound come on.
Do you guys think it is the same ABS problem or this is different ?
