Circuit/System Description
WARNING: This page is about a different car, the 2010 Buick LaCrosse. However, it is still accessible from the selected car via links, so may be relevant.
The yaw rate, lateral acceleration and longitudinal acceleration sensors are combined into one multi-axis acceleration sensor, external to the electronic brake control module (EBCM). The EBCM controls the stability control by monitoring the inputs of the yaw rate sensor, lateral acceleration sensor, and steering angle sensor. The readings are compared to an internal calibrated value so it knows if the vehicle is having an instability condition to activate the stability control.
