2002 Lexus GS430 warning lights and loud high pitch ringing sound.
2002 Lexus GS430 warning lights and loud high pitch ringing sound. These warning lights: BRAKE, VSC, ABS, VSC OFF.
Does anyone know what this combination of warning lights might mean in addition to the high pitch ringing sound?

Ringing in the car or more like a screeching sound from the engine bay?
My lights went on like yours when my alternator went bad. Maybe alternator bearings going bad, causing the screeching/ringing sound and the lights to come on.

It's you master cylinder/booster. The ringing noise you hear is the break booster failing to prime and eventually you can lose pressure on your lines at any time. Please view my latest thread I've recently had a very close call when mine had a catastrophic failure. There around $1200 new $250-400 used/junkyard I just swapped mine from an 02 gs430 the 02 cylinders are supposedly redisgned and have a way lower failure rate. It took about an hour only thing was the pressure sensor has a different plug so I cut the wrecker car harness and soldered it into mine. I wouldn't drive it until this is addressed.
