2007 prius master warning light, (!), VSC and engine light on

SOURCE: my 2008 4runner is displaying a vsc warning light

Need to pull codes from computer to find defective sensor

I had the same problem. A computer check showed that the emission system was having difficulty. The catalytic converter had to be replaced. The car had under 80,000 miles on it so it was covered by a warranty (State law? Federal law?).
My battery was also dead. That was replaced free too. It had a 7 year warranty.
I do NOT purchase extended warranties.

Please, make your mechanic check the ABS computer. My RAV4 did the same thing, but the mechanical components were alright. After a while, I almost fell off a cliff because my brakes stopped responding properly. When further checked, my mechanic discovered that the ABS computer was damaged. The part alone costs a whooping $3 thousand bucks, not including labor. So, beware and take precautions. Your life may be endangered.

SOURCE: I recieved the following Warning lights: VSC and Engine Check

You have an issue with the engine. The other lights come on when the Check Engine light comes on. The most common reason for the Ck Engine light on is a loose gas cap. If the cap is tight, you will need to find someone who can scan the car's ECU and give you the DTC code. Without the code, we cannot provide any more ionfor at this time.Get the code and get back to us; then we can solve the problem.
