vsc, vsc off, traction control light, check engine lights

I started a new thread with the above lights because I had done an extensive search and found the gas cap THEORY. It may have fixed some of yours but I bought a NEW toyota gas cap and after a week the lights are back on. SOEEEE my question is this, has anyone found out what the issue is other than the gas cap. Thanks

VSC and TRAC lights will be on because the check engine light is on. You will need to have someone with a scan tool check what codes you have so you can properly repair your vehicle. once you make the proper repairs from the CEL after several drive cycles, the CEL will turn off along with the VSC and TRAC
