Kia Sportage: Yaw-rate and Lateral G Sensor | ESC OFF Switch

Kia Sportage Third generation (SL) - (2011-2016) - Service and Repair Manual / Brake System / ESC (Electronic Stability Control) System / Yaw-rate and Lateral G Sensor | ESC OFF Switch

Description and Operation

 Description

When the vehicle is turning with respect to a vertical axis the yaw rate sensor detects the yaw rate electronically 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.

The later G sensor senses vehicle's lateral G. A small element inside the sensor is attached to a deflectable lever arm by later G.

Direction and magnitude of lateral G loaded to vehicle can be known with electrostatic capacity changing according to lateral G.
