Yaw-Rate Sensor And G-Sensor: Description: Notes

The yaw-rate & lateral G sensor is applied for the ESC system.
The yaw-rate is the angular velocity, when a vehicle turns a corner, and the lateral G is the acceleration to move a vehicle out of the way when cornering.

The sensor is located in the crash pad lower floor on vehicle.
