Circuit/System Description

The steering angle sensor shares a 12 V reference voltage with the electronic brake control module (EBCM) and the yaw/lateral accelerometer sensor. The EBCM applies a ground to the steering angle sensor low reference circuit, which is shared with the yaw-rate/lateral sensor.

The steering angle sensor provides a serial data signal output to the EBCM that represents the steering wheel degree of rotation. The EBCM utilizes this signal to calculate the driver intended driving direction.
