Circuit Description
WARNING: This page is about a different car, the 2007 Pontiac G6. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module (EBCM) monitors the voltage level available for system operation. If the voltage level is too high, damage may result to the system. When the EBCM detects a high voltage condition, the EBCM disables the ABS system.
