LKAS is a steering assist system 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. Based on vehicle speed signals transmitted via Cluster, LKAS determines the vehicle speed to control steering force.
While communicating with the Cluster module, if an invalid signal is received, the LKAS module generates the fault code C163387 and turns on the Malfunction Indicator Lamp.
