The VSC light on my Toyota 2005 4 runner just randomly came on. I had a bad negative battery cable and replaced it. After replacing the cable the light went out for two days now it is back on and the check engine light is on as well. The vehicle drives great any advice is appreciated, thanks.

What I need you to do is have the computer scanned to determine what codes are causing the lights to come on. Most parts stores will do it for free. Have that done and let me know what codes are found so I can better inform you.

That doesn't deal with the VSC. That code indicates there is a leak in the EVAP system. Basically, something like a loose gas cap, damaged lines. Are allowing vapors to escape from the fuel system.

As far as the VSC, were they able to retrieve any codes related to it?

Basically they said what you said possible bad gas cap. They reset the codes and so far VSC lights are off. I am going to monitor this a few days the gas cap still clicks when tighten not sure if it works itself loose cause the code and/or check engine light. Vsc not sure but lights are out after the reset.

Let me know what happens. Before just purchasing a new gas cap, have it tested. If it checks good, you will need to have the EVAP system smoke tested. Basically, at a very low pressure, smoke gets pumped into the system. Wherever the leak is located, the smoke will come out.

Let me know if I can help further.
