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.
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.
