ABS kicks in sometimes when I turn (1 Viewer)

[albertliang3]

Hi guys, I have a 2002 lx470/lc100, took it up the mountain recent few weeks. I am running 35s with 2.5in lift, no regear. I notice sometimes (this happened 3 times going up and down the mountain) when I turn left, the speed is not even fast, and ABS kicks in and brakes for me, it kinda drives me crazy.

I already checked the bearing by jacking up the truck and tested it by holding up the bottom of the tire and shaking, both wheels and super snug no play.

One thing I changed during the past month is the outer tierod on the right side and the alignment right after it.
What it could be? Thank you, guys, would be appreciated.

@albertliang3 - Google this. Many Toyotas do it, and the cause isn't super obvious. It's your stability control falsely kicking in. Some attribute it to loose wheel bearings, and some to bad sensors. Few have found a simple solution.

Try a zero point calibration on the VSC unit. You can do it with a scanner or shorting out pins.

Is it the ABS or the VSC? Are there lights on the dash? Is this mountain road dirt/gravel?

The abs light is flashing sometime I turn, and it brake for me.

I had a similar issue years ago. My left front sensor was intermittently throwing a code.
I tried to replace the sensor and broke it trying to remove it, took the wheel off to do a full repack, replace seals and surprise. The seal behind the knuckle let mud in and the surface where the sensor reads was caked in mud.
I would check that first at it threw codes exactly as you describe with yours, low speeds, turning and intermittent.
The gap between teeth's where full off mud

I think that the best explanation is that the steering rack bushings are shot.

VSC overly sensitive, activating during mild turns in normal driving: problem finally solved

Since I got my 2001 LX470 in 2020, going around a normal turn at normal speeds (say, a normal 35 MPH road curve) would produce VSC beeping, sometimes even kicking in the ABS for an abrupt forced slowdown. The only code coming up was for steering angle sensor. We replaced and reset that thing...

lx470 the vsc warning light goes on

On my 2000 Lexus lx470 the vsc warning light goes on, sounds a very loud beep and brakes are applied hard on freeway at 50 mph in a long sweeping left turn. Speed limit on this freeway is 70. the car dive hard to left and scares the @!$#$ out of me when it happens. it is now increasing in...

Steering rack cured it for me.
