What does yaw rate sensor tell VSC to do?
Yaw rate sensor(also called angle speed sensor), inspect the deviation of vehicle along the vertical axis. The deviation represents the stability degree of vehicle. If the deviation angle is up to certain threshold value, it indicates that side slide occur or the vehicle has danger of excursion, so at this time VSC controlling will be triggered.
What does it mean when your VSC light is not working?
Whenever a VSC light is illuminated, it means that the traction control of the car is not working. Mostly when there is a problem with the O2 sensor or gas cap, then you can see a small light on your instrument panel near the steering, which indicates that there is some problem.
When to do yaw rate and acceleration sensor zero point calibration?
IF your 4Runner is equipped with either DAC or Crawl Control, you must complete steps 4 and/or 5 or you will get a DTC and the slip indicator will always be lit. I highly recommend this calibration if you think the VSC on your 4Runner kicks in too much, before or after lift.
How do I Turn Off Trac and VSC light?
If you want to turn off both TRAC and VSC, then press hold the button for few seconds (3 seconds approximately); this way, both the indicators of TRAC OFF and VSC OFF will be seen. In the same way, you can turn on both by pushing the button again.
How to calibrate the yaw rate and acceleration sensor?
PERFORM YAW RATE AND ACCELERATION SENSOR AND STEERING ANGLE SENSOR ZERO POINT CALIBRATION (When Using SST Check Wire 09843-18040) While obtaining the zero points, keep the vehicle stationary and do not vibrate, tilt, move, or shake it (do not start the engine).

Is there a zero point calibration for yotatech?
This is right out of the repair manual. Number 3 is probably the method used in the yotatech link. SST 09843-18040 from a little research is supposedly just a jumper wire but you’ll need to confirm that. I’ve never done zero point calibration before.
