Circuit/System Description
WARNING: This page is about a different car, the 2010 GMC Sierra and 2010 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module (EBCM) receives data from other Modules (ECM, BCM, TCM, TCCM, and Hybrid Control Module) and the yaw rate sensor/lateral accelerometer sensor which are needed to perform brake control functions. The EBCM must ensure that all serial data and sensor inputs are properly received and learned.
