VSC light came on, why?


Most of the time the VSC light will come on with check engine and trac off light. (picture of veh with squiggle lines behind it) Whatever triggers a Check eng turns the vsc and trac systems off. could be a loose gas cap or something related to emissions system. Most times it will have to be diagnosed. Veh maybe equipped to turn vsc off, there would be a button for it.

When starting my lexus GX 470 the vsc off light and vsc trac light go on what is the problem .


The VSC on TRAC off lights will come on when there is an air fuel related issue.
If you have recently filled your tank, unscrew and tighten the gas cap till it clicks. The lights may need to be reset if they stay on after that. They will also be triggered by a fouled O2 sensor ins the engine or exhaust as well as a sticky throttle valve.
If a dealership resets the lights they can attach a code reader under dash to determine the cause in about 5 minutes.

My 2006 scion xb vsc,traction, and check engine light just came on what is the problem please help quick


I had the same problem. The cause (at least on my box) was a bad charcoal canister and the valve going to it. These go bad on the boxes fairly often. If you "top off" your tank, the overflow spills down into the charcoal canister and it will not function properly. IE: Engine, Trac, and VSC lights come on. It doesnt hurt it to drive with a bad canister, but you will lose mileage and that light will be staring you in the face every time you drive. The parts are pricey, dealer only parts and the canister is about $400. I found a totalled xb with a good canister and nabbed it for $40.....solved my problem. Hope this helps!

THE VSC TRAC OFF & CHECK ENGINE LIGHTS CAME ON ....my friends say its no big deal and its common with all toyota cars buta am just not confortable driving in it anymur. please help.....


1. VSC means Vehicle Stability Control.

2. TRAC Off means Traction Controln is off

3. Check simply indicates that there is an issue being communicated from the onboard computer.

Take the car for a scan dear.

VSC Trac off lights on dashboard


I have just had the same problem this morning for the first time and I suspect it is just bad gas. We have had problems with the check engine light in our camaro whenever we bought hi test at the Mobile gas station closest to our home. I would not be surprised if this same gas station is now having water problems with their regular gas which is what we put in our 4runner. Try STP gas treatment first, which is what I am going to do now. When I used this approach with my camaro, the light went out within a few days. Technically, a sensor might have been damaged, but my thinking is that if that sensor is dead, then my fuel/air mixture will get bad enough to notice pretty quick. The TRAC off and VSC off are just extra lights that go on, whenever the check engine light comes on. I'll let you know how it goes.
