Operation
1. When the lane-keep assist system OFF 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 OFF 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).
