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.

I have LX470 2005. Sometimes when accelareting, VSC off and VSC TRAC get on. When they get on, I switch the car off and on VSC alarms get off.What could be a reason?


HI,

For your Lexus this may be the same as a Check Engine Light, which is telling you something needs attention.

Take the LX to an Auto Parts store and asked them to scan your car for codes stored in the engine's computer (ECM or PCM). They'll usually do this for free.
Possibilities:
- Loose gas cap
- low brake fluid
- O2 Sensor(s)

Also, Your LX is very similar to the Toyota Sequoia which also had VSC issues. Search online and you may find your answer.

GL,
TD

VSC OFF CHECK ENGINE INDICATOR


If you have recently filled your tank, release and then tighten your gas cap.
VSC check engine lights are often triggered by a loose cap or fouled O2 sensor. If the light stays on for several more days of driving you may need to have a fault code reader plugged in at a service center and the lights reset after determining the cause. Get the details on a printout for future reference and psot back with results
