Brake System

EPS (Electronic Stability System) - Yaw-rate

And Lateral G Sensor

Brake System

2009 > G 2.7 DOHC >

DESCRIPTION

1. The yaw-rate & lateral G sensor is applied for the ESP system.

2. 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.

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