Circuit/System Description

The lane departure warning system is controlled by the front view camera module mounted on the windshield. The lane departure warning is enabled and disabled through a switch located on the instrument panel. When enabled, the front view camera module will illuminate the indicator located in the switch.

When the system is operating and can detect the lane markings, the front view camera module will request via serial data communications that the instrument cluster illuminate the green lane departure ready-to-assist indicator. If the front view 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 will also sound three times when the yellow instrument cluster indicator is flashing.
