Circuit/System Description
WARNING: This page is about a different car, the 2014 Chevrolet Sonic. However, it is still accessible from the selected car via links, so may be relevant.
The lane departure warning is enabled and disabled through a switch located on the steering wheel controls - left. When the switch is pressed, the frontview camera module will disable or enable lane departure warning. When the lane departure warning system is enabled, the frontview camera module will illuminate the indicator on the switch. The indicator receives voltage through a high control circuit from the body control module (BCM) and is controlled through a low control circuit by the frontview camera module.
