Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
The lane departure warning system is controlled by the Active Safety Control Module. Lane departure warning is enabled and disabled through a switch located in the instrument panel. When enabled, the Active Safety Control Module will illuminate the indicator located in the switch.
When the Frontview Camera module is operating and can detect the lane markings, the Frontview Camera module will request via serial data communications that the instrument panel cluster illuminate the green lane departure ready-to-assist indicator. If the Frontview Camera module detects that the vehicle has crossed a lane marking without the turn signal being used, the module will request that the instrument cluster flash the yellow lane departure warning indicator. An audible warning may also sound three times or the haptic seat (if equipped) may pulse when the yellow Instrument Cluster indicator is flashing. The driver can select between audible or haptic alerts in the vehicle personalization menu. See the Owner's Manual for more detailed information on vehicle personalization.
