Circuit/System Description
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. 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/longitudinal accelerometer sensor, external to the electronic brake control module. The electronic brake control module supplies a 12 V reference to the accelerometer sensor. The accelerometer sensor communicates with the electronic brake control module via serial data. The module activates the stability control and the hill start assist function depending on the information received from the accelerometer sensor.
