Circuit/System Description
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The electronic brake control module (EBCM) communicates the input of the drivers intended braking torque via the control area network (CAN) circuit to the engine control module (ECM). This information allows the ECM to make adjustments to various engine control functions when the driver applies the brake.
