Circuit/System Description

WARNING: This page is about a different car, the 2011 GMC Cab & Chassis Sierra, 2011 Chevrolet Suburban, and 2011 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The yaw rate, lateral acceleration and longitudinal acceleration sensors are combined into one yaw/lateral accelerometer sensor, external to the electronic brake control module (EBCM). The EBCM supplies ignition voltage to the yaw/lateral accelerometer sensor. The vehicle stability enhancement system uses the lateral accelerometer input when calculating the desired yaw rate. The EBCM receives the yaw/lateral accelerometer sensor data from dedicated serial data circuits.
