Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
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.
