Stability Off Indicator
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 IPC illuminates the Stability Off indicator when the electronic brake control module (EBCM) detects a malfunction in the vehicle stability enhancement system (VSES). The IPC receives a class 2 message from the EBCM requesting illumination of both the VSES indicator and the TRAC OFF indicator. The EBCM disables both the vehicle dynamic system and the traction control system.
