2009 4Runner VSC OFF + TRAC random problem

[Fxgo]

Good day,

My 2009 4Runner has this electronic gremlin nobody seems to be able to fix.

Sometimes, when turning (mostly right) at low speed, the VSC OFF starts blinking and TRAC light (the light with the car on it) lights up solid, both at same time.

This never happens at highway speed or when going straight. Always during turns at low speeds.

When this happens, if I shut down the truck and start it right after, the lights are off.

Is there any known cause to this issue? Mechanics seems clueless and will just charge for computer reset, which doesn't solve the issue.

Thanks for your help.

heres a couple threads that may help. http://www.toyota-4runner.org/5th-g...celeration-sensor-zero-point-calibration.html Zero-Point Calibration VSC 04 4Runner - YouTube http://www.toyota-4runner.org/probl...ac-vsc-off-lights-zero-point-calibration.html

Thanks, I did read these threads, however:

The specific behavior: On startup, the "VSC TRAC" and "VSC OFF" lights come on and stay on.

This is not my issue. They turn on only at low speed during turns.

just resetting wont solve anything if theres a problem, were there any codes? theres alot of threads on this & not all deal with the lights being on all the time, i was trying to steer you toward posts on the "zero point calibration" either way, heres another that might help. http://www.toyota-4runner.org/4th-gen-t4rs/105406-vsc.html
