The VSC light came on at approximately 62000 miles. Took it too a mechanic who put it on computer, found gas cap loose, and reconnected hose under air filter however no code shows on the computer for a fix. The VSC light still remains on. Tried all the internet fixes; pulling fuse & disconnecting battery cable. The light goes out but as soon as I move the car it comes back on. Is there anything I can do to avoid a large dollar visit to the Lexus dealer since there are no driving or stopping symptoms with the car.
