the abs sensors( 4 of them ) are located at each wheel near the brake rotor or in the live axle housing close to the wheel
the trac control uses the same sensors and it only takes one faulty unit to put the lights on
the fault can be from a broken wire, wire fallen out of holder

I have a 2004 sequoia with the same problem. VSC TRAC, TRAC OFF & brake light comes on at the same time. Sometimes just the brake light and other times all three. Sometimes no lights. Does anyone have a fix?
NEED TO HAVE COMPUTER CHECK FIND WHAT CODE MADE THE ENGINE KLIGHT COME ON.. AND HAVE IT FIXED,, VSC LIGHTS COME ON BECAUSE THE COMPUTER DEACTIVATES THE VSC AS A SAFETY FEATURE WHEN CK ENGINE LIGHT IS ON
It is not hard to change the sensor, it just screws into a threaded hole. The light will not go out immeditaly, after the sensor is replaced. It needs to go thru a drive cycle. Your best bet is to replace the sensor and get the code cleard by whoever scanned it for the 0031 code.
You have to know what code is stored to fix the problem. Toyota's will generally display a Check Engine light, VSC and TRAC light all at the same time, even if it's a simple problem with an oxygen sensor (for example). You can disconnect the negative battery cable for a few minutes, even though you should a scan tool should be used, to clear out the code.
I did research on line and all indicates that is caused by the YAW RATE SENSOR. It nedds to be replace and adjust. I have the same problem but havent find the time to get to it. When I do I will post it. If you do it before I do please email me with the result at firstname.lastname@example.org
