When I try to start my Lexus LX 470 2001 the "check" lamp does not light but "vsc off" and "vsc trac" light and does not go out and the engine does not start. What is the problem?

Often caused by a loose gas cap or fouled or failed air fuel O2 sensor. Check your gas cap is fully ratcheted, Drive a day or two. If lights don't clear you will need a code reader attached to the car to diagnose.

The VSC on TRAC off lights will come on when there is an air fuel related issue.
If you have recently filled your tank, unscrew and tighten the gas cap till it clicks. The lights may need to be reset if they stay on after that. They will also be triggered by a fouled O2 sensor ins the engine or exhaust as well as a sticky throttle valve.
If a dealership resets the lights they can attach a code reader under dash to determine the cause in about 5 minutes.
