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 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. The TCU signal is used to determine whether the reverse gear is selected, and, if it is selected, the LKAS control stops.
While communicating with the VDC module via CAN, if a valid signal is not received from TCS, the LKAS module generates the fault code C162587 and turns on the Malfunction Indicator Lamp.
