The lane departure warning system is enabled and disabled through the lane departure switch. When enabled, the lane departure warning switch indicator will illuminate. The switch and indicator are connected to the frontview camera module. The frontview camera module supplies a reference voltage to the lane departure switch. When the switch is pressed, the signal circuit is grounded. When enabled, the frontview camera module will illuminate the indicator located in the switch when lane departure warning system is enabled.
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 illuminates the green lane departure ready-to-assist indicator. If the front view camera module detects that the vehicle unintentionally crosses a lane marking without the turn signal being used, the module will request the vehicle direction display to flash the amber lane departure warning indicator. Anr audible warning will also alert three times when the amber lane departure warning indicator in the vehicle direction display is flashing.
