Circuit/System Description
WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module (EBCM) controls the vehicle stability enhancement system (VSES) by monitoring the inputs of the yaw rate/lateral accelerometer sensor, and steering wheel 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 VSES. When the readings indicate a VSES event is occurring longer than 10 seconds is not possible under normal conditions. The yaw/lateral sensor is a combination sensor in one component.
