Toyota 2005 Rav4 - My VSC Trac light is now on. Before this, I had both the Engine Check Light and the VSC Track light on at the same time. I checked the codes at Advance Auto and Auto Zone. It gave me a code with 3 things, Emission Control Valve, Emission Solenoid Valve, or the gas cap is not sealing correctly. I looked at the gas cap and the gasket was flat on one side so I replaced the gas cap. i then took the negative battery cable off for 30 minutes to clear the codes, then reconnected the battery cable. Momentarily no lights were on, the Engine Check Light was now off. I started the vehicle. The vehicle was not driven then the VSC Trac light came on. I took the vehicle to Advanced Auto to read the codes and there were none. How do I get the VSC Trac light off? What is the problem now?
