Vsc light on in lexus rx 300
How to fix

Stop Engine, Start Engine again the Vsc light is off.
sometimes Vsc Light is on again

 

It could be something with the rear wheel speed control sensors. Check the code to find out if you are dealing with the left side or the right side of the car.

Thank you so much

 

if it IS related to speed controls....do you have mismatched tire sizes? Like new tires in the rear and older tires in the front? if so rotate the tires and see if it goes away
