•  The lane-keep assist system can be turned on or off optionally by the driver.

•  The switch operation signal is sent to the instrument cluster.

•  The indicator light turns on when the lane-keep assist switch is on.

•  The lane-keep assist system switch is built into the cluster switch.

1.  When the lane-keep assist system switch is operated, a cluster switch operation signal is sent (1) to the instrument cluster.

2.  The instrument cluster sends (2) the lane-keep assist system switch operation signal to the forward sensing camera (FSC) based on the switch operation signal (detected voltage).

3.  When the FSC receives the lane-keep assist system switch operation signal from the instrument cluster, it switches the lane-keep assist system on/off (3).

4.  The instrument cluster turns on (4) the transistor when the lane-keep assist system switch is on.

5.  When the transistor turns on, a ground circuit with the indicator light is established, and the indicator light turns on (5).
