LKAS is a device that maintains the vehicle within a lane by detecting the lane via a camera, calculating the vehicle position and the steering force required to keep the vehicle running in the center of the lane, and controlling the vehicle accordingly. The system consists of a LKAS unit, cluster, MDPS and power switch. Before the LKAS camera can operate properly, it should be mounted on the vehicle and calibrated appropriately. Otherwise, the LKAS indicator on Cluster will blink.

If the lane recognition camera has been shipped without being calibrated at the factory, the fault code C272154 is generated and the LKAS indicator on Cluster blinks.
