2017 Hyundai Elantra Limited ABS and automatic headlight fault

When I purchased this car I noticed that if I turned on my automatic distance sensors and lane assist then turned the vehicle off. The next time I turn the vehicle on my abs light and a message saying there’s an abs and automatic headlight fault occurring. To combat this I just stopped using lane assist and automatic headlights. Now, however, the lights have come back un-provoked and I am wondering if this is an ABS sensor issue or a wiring harness issue??
