C1251 BUICK Description
The Continuously Variable Road-Sensing Suspension (CVRSS) calculates normal force and transmits a signal to the Electronic Brake Control Module (EBCM) via two dedicated data lines, one right, and one left. The EBCM supplies the pull up voltage. The EBCM uses this information to detect rough road conditions and allows for more aggressive braking on rough surfaces.
