I have a 1999 LS400 with 67,000 miles on it. I also am having the VSC Off light and the CEL come on at the same time, the Check VSC error message comes on and I my car dies. It does this when I let off of the gas, like when I am going around a corner or through an intersection. It is very scary. This happened one time last year and I called the dealership, the mechanic told me to make sure that my gas cap was on very tight. I tightened it and the problem went away. Now it has happened several times over the last few days and today when I was driving home my car quit 5 times. I have to pull over, stop the car, turn it off, then turn it back on, and put the gas to it right away to keep it running.
I called a local mechanic that replaced the brake sensors on my car a little over a week ago. He said that it was a problem with the transmission. That didn't make any sense to me at all, although I must admit I know very little about the mechanics/electronics of this (or any) car. I am a pretty quick study though and want to understand it before I take it in to either the dealership or another mechanic so that I don't get taken advantage of.
Per the suggestion, I will take the car over to a local AutoZone tomorrow.
I have two questions. 1. What is the cause of this problem? 2. Could the mechanic that replaced my serpentine belt and brake sensors last week have contributed to this problem?
Thanks so much for having this great forum.
