Kia Sorento (XM, 2011-2015) Service Manual / Brake System / ESC(Electronic Stability Control) System / Yaw-rate and G Sensor Description

The yaw rate and G sensor is included inside the air bag control module (SRSCM).
When the vehicle is turning with respect to a vertical axis the yaw rate sensor detects the yaw rate electroniclly by the vibration change of plate fork inside the yaw rate sensor.
If yaw velocity reaches the specific velocity after it detects the vehicle'yawing, the ESC control is reactivated.
