VSC lights always go on during a "Check engine" period so just get the engine fault code and DIY or go to a TRUSTED mechanic (or someone you trust goes to).It is likely an emissions problem.
As long as it does'nt stay on it's doing what it's suposed to be doing which is saving you from going out of control. It'll come on more often if you drive like hell, run with low tracktion tires or worn out ones and if the air pressure is low. If your tires have over 80,000 miles on them even if the tread is still good their bad tires as their skating along and the trackstion system is working hard to keep the car under control. If the tires aren't al the same size it'll do it to. ( fronts worn out backs still with tread.) Mis matched tires too. Ifthe light stays on other light's are bound to be coming on too the ABS light the brake light, and even the engine light as their all involved in traction control.
When the computer detects certain faults it will set the check engine light on along with the other lights you've explained. I've seen this on many toyota SUV's. Usually the codes set are oxygen sensor related. There really is no relation between the oxygen sensors and the traction control system but for some reason it disables it and sets the warning lights on. Have the computer scanned for codes at a shop or at a parts store such as autozone for free.
You have to use a scanner and pull the code out that is causing the check engine light to come on. whatever code/codes you find are probably related to vsc light.
Good luck and keep me posted
the vsc and trac lights illuminate because of the check engine light. you need to have the check engine light diagnosed or pull the codes and i can help you
This could be two seperate problems but the trac and vsc lights can come on when the check engine light does for a number of codes. Have the check ngine light scanned to diagnose the problem. When the problem that caused the engine light to come on is resolved and the code cleared the tra and vsc lights should turn off as well. Rarely they will stay on in which case your toyota dealer may have to do a "zero point calibration".
Those lights always come on whenever the check engine light is on.It could be from the gas cap not being tight enough or an air hose
in the engine compartment coming loose. I recommend bringing your vehicle to someone that can read the codes and reset the lights for you. The codes will narrow down what the problem really is.
