Circuit/System Description

The steering wheel angle sensor receives a 12 V reference from the electronic brake control module. The electronic brake control module receives serial data message inputs from the steering angle sensor identifying the position and direction of the steering wheel rotation. The module utilizes this signal to calculate the driver intended driving direction. In vehicles equipped with adaptive headlights, the Headlamp Control Module uses the steering angle signal to aim the headlights in the direction the wheel is turned.
