LKAS determines the current vehicle speed based on signals from the vehicle speed sensor and uses the vehicle speed to determine lane-keeping control conditions. The vehicle speed signals transmitted via Cluster are transferred to LKAS. Based on these signals, LKAS determines the vehicle speed to control steering force.

LKAS takes various vehicle conditions, including vehicle speed, yaw rate, and other data from horizontal acceleration sensor, direction indicator lights, steering column and cluster, as input via CAN High and Low lines. Based on these signals transmitted via Cluster, LKAS determines the vehicle speed to control steering force.

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.

If an undefined vehicle signal is sent by Cluster via CAN lines, LKAS generates the fault code C163386 and turns on the Malfunction Indicator Lamp.

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.
