LKAS takes various vehicle conditions, including vehicle speed, yaw rate, and other data from horizontal acceleration sensor, direction indicator lights and steering column, as input via CAN High and Low lines to control MDPS.
If an undefined signal is received from Steering Angle Sensor (SAS) via CAN lines, LKAS generates the fault code 167286 and turns on the Malfunction Indicator Lamp
