Need some help from the experts! While sitting in the driveway the other day the "Check Headlamp System" warning message appeared and pops up every time I start the vehicle. The vehicle is a 2017 GX with luxury trim and driver support package. Except for a GROM apple carplay, the vehicle is stock and drives and performs great. All functions of the car appear to work as normal. Anybody ever had this issue before? Any ideas on what it could be?

Hey hello there OP, did you ever resolve this error, my GX460 2015 luxury have the same exact problem, i do notice humidity inside my headligghts and the check headlight system message pops out right after i turn on my lights, they all work just fine but i get the error. The error code i get btw is the B2430 LED Headlight LH.

 

FSM shows this for B2430

 

I noticed yesterday that auto headlight function wasn’t working, so I think this is what “check headlight system” message is about. Does anyone know how to fix this issues?

 

@tekstein Do you have anything to pull codes?

If you don’t have Techstream setup this works well
