2004 SC 430, headlight leveling indicator comes on. I rebuilt or cleaned the sensors both front and rear. The light then no longer came on, I think it was good news until the temperature outside dropped. When the temperature is colder outside, the indicator comes back on until it warms up outside. There seemed to be multiple connections to connect the sensors to the system. Any ideas? Thank you for your help.

 

I wonder if this thread might help you…
