2007 Toyota Prius VSC dash light

The VSC system on the Gen 2 Prius cannot be turned off. If the dash light is not lit under normal driving, it is functioning properly. You don't have to worry unless it turns on and stays on.

 

Hmm, I'm not sure about that then. I have not seen anyone on here talking about replacing burnt out bulbs for dash lights. I'm guessing they are LEDs and just don't burn out. In your first post you said that the VSC light does turn on when you turn on the car. Are you saying it does not turn on only when you insert the key as opposed to using the Smart Key system to start it with the key in your pocket?

 

Just to clear up something, as I can't really understand clearly what it is that is happening for the OP.

The self-check routine does not occur when you insert the key in the slot. It occurs when, with the key inserted (with non-SKS) in the slot, you have your foot on the brake and press the power button once. As part of the startup, the computer will illuminate all the lights for about 1 (or 2) seconds, except the Master Caution Light, then all the lights should then turn off.

So can the OP clarify what behavior is causing concern?

And btw, if you leave your foot off the brake and press the power button twice, all the lights illuminate (again except for the Master Caution Light) and stay on.

 

That would suggest the light that illuminates that LED on the light cluster has failed.

 

Or if the OP’s car is not at least an Option Package 2 model, it does not have VSC.
