vsc and trac control lights keep coming on

[virginiayota]

so at random times (some times couple weeks somtimes couple months) the vsc trac control, service engine and matience lights will come on. All of those systems will be off and you can burn the the tires not that i want to. I reset the computer everytime by unpluging the battery for 30 secs. It will be fine again for weeks or months. Iv replaced the fuses just in case even though they were not blown. Just wondreing if i got a lemon or if anyone else has this problem. last place Im gonna go is the dealer. Its an 05 sr5 v6 4wd

Mine are on as well, I have had it checked two times at different part stores. I have a bad O2 sensor, just haven't spend the $90 to replace it yet. Go have it plugged up to a diagnosis machine, its free.

yea i got a computer programmer and there are no codes coming up. as I said reseting the computer works every time and my buddy who has been building yotas all his life cant figure it out.

thanks i will give it a try. do i need to wait till it happens again?

No, just give it a try now and drive her.
It is very easy just do as it says and watch for the lights to flash.
It was so easy that even I did it.
