Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question
90% or more of the electronics in your vehicle is controlled by one of the many on board computers. This means that diagnosing is done with a factory level scan tool to communicate with them as well as do various testing thru them using command functions. This is why they are able to diagnose it without removing anything to get to the lighting systems.
There simply is no way to diagnose the adaptive lighting system without the proper scan tool and no way to repair, program, or erase the fault codes that set the light.
Sorry, I am not the one the designed and engineered your vehicle. Nor can I help it that the issue you have right now REQUIRES the use of a factory level scan tool. I guess I could have lied to you and gave you a bs method that wouldnt work, but I assumed you were actually wanting an accurate and honest answer. Have a good weekend
