This is the traction control of the vehicle, preventing uncontrollable skidding in hard braking or steering situations.
The Lexus GX 470 VSC trac light is on because your vehicle is experiencing electrical sensor issues. Take your Lexus to your auto body shop to remedy the problem.
It's for better traction in the snow.
Problem with emission system - have vehicle scanned to determine problem
The TRAC OFF light is usually caused by a problem in the ABS system. See the link TRAC OFF DESCRIPTION link below for more info.- TechJK -------------
I had the same issue so I took it to Lexus for repairs. It seems that light comes on everytime there is a fuel issue rather than a traction issue. You could take it to an Advance Auto and have them pull the code from the computer and it will tell you the problem before you take it to Lexus or your favorite automotive shop. I believe the image they should be using instead of the trac off light is a dollar sign! Last time it went off it cost me 700 dollars.
Have the ECU scanned with an OBD2 scan tool.
If your engin light also is on, you need new oxigen sensors!
Trac off means your traction control is turned off.
Problem with the ABS.
there is no problem....great vehicle!
