LKAS takes various vehicle conditions, including vehicle speed, yaw rate, steering angle signal and other data from horizontal acceleration sensor, direction indicator lights, steering column and cluster, as input via CAN High and Low lines. Based on the steering angle, LKAS determines the steering wheel position to control steering force.
While communicating with Steering Angle Sensor (SAS) via CAN, if the transmission cycle of SAS signals is not normal, the LKAS module generates the fault code C167282 and turns on the Malfunction Indicator Lamp.
