Default VSC Light on

Hi
I have a problem with my Lexus is 250 2008r lift.
My problem is with the VSC light on.The problem is strange, the computer does not show errors.
VSC light most often lights up when the car is hot in the middle of the sun.
It also happens that there is light at the first start of the engine when the stairs are in traffic, or the car goes without slipping wheels
The VSC light resets when I turn off the engine, but after a few minutes or kilometers, the light will be able to appear again
ABS works, I have not noticed the bad effects of VSC light. In addition to being annoyed and wanting to solve the problem.
Same VSC light, no check engine.

I replaced the gas cap, but that did not help
The dealer checked the active test and all the parameters are ok.


What could happen, someone had a similar problem?


Sorry for my english.

VSC is Variable Stability Control.

Do a search on Google.

Good luck.

In my case, the VSC does not Blink. It only lights up permanently

I know what is VSC....


Google
The VSC warning means nothing -- VSC shuts off due to any of a plethora of causes with most having nothing to do with VSC. Maybe the purpose of of the VSC warnings is to our attention. I've had the VSC warning on my LS probably four or five times including when the car was still under it's basic warranty and not once was there a problem with VSC.
Forum Lexus UK.
I can't find more information about my problem. That is the light-up VSC without cause

It’s probably one of the wheel speed sensors going bad. If you can get a scanner with ABS function. It will let you see which one is bad.

The problem is that all ABS sensors show the same speed of the wheels and the scanner does not show ABS errors

If your mechanically inclined. Pull the wheels off, and remove each one from where it’s mounted. They could have metal shaving build up. Also while your at it check resistance with an OHM meter. You’ll have to disconnect the harness from the frame to check both pins.

ok, i will try to check the ABS electric bundle.
Without the VSC light on the dashboard - it will measure good?.
Wait until the VSC light appears and use the OHM meter?

Problem with ABS sensor should be constant?
In addition, the problem with ABS should rather show ABS light + VSC light all time on the dash.

My VSC light resets most often when the engine is shut down. After that, he will not light up until the end of the day
Thanks, I will try to do this test with a meter

Yes I’m sure it should be on always. Just the VSC light on is a little hard to diagnose, but the speed sensors are associated with that feature of the VSC. Like you mentioned in your first post about hot weather. Leads me to believe something is losing signal. Let us know what you find out.

I agree with you on that one, a friend's IS250 once did that.

What scanner are you using? Its probably a Lexus specific code that a generic scanner will not pick up. Find out what the DTC is first.

My check system has always been on since Ive replaced my wheels. But now I have the VSC light on, I replaced the gas cap thinking it was too old. Just looking for a resolution.
