LKAS is an abbreviation of Lane Keeping Assist System. 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 lead the vehicle into a safe zone, and controlling MDPS with the calculated results. The system consists of a LKAS unit, cluster, MDPS and On/Off power switch. The main components of the device are CMOS Image Sensor (CIS), Digital Signal Processor (DSP) and Micro Control Unit (MCU; CPU).
LKAS ECU monitors ECU components such as memory to see if they operate properly. If abnormal operation of the ECU hardware is detected, ECU generates the fault code C160404 and turns on the Malfunction Indicator Lamp.
