OK...Did a little more research..Thank you , thank you T/S forum.

I take very good care of my sequoia. In fact I request/have the 4 wheel alignment done twice first at 18K miles then again at 35K miles. ( I do this to keep the tire wear down)
Now I've got the VSC/Trac Off light w/ the Engine Light. The truck ( 04 Sequoia bought in 12/03) has 41,800 miles on it now, and is just out of its 3 yrs ( by 5 mo.) and 36K warranty ( by 5,800miles). The dealer says the VSC ECU must be replaced. ($1,780).!!
I see that there are TCB's for it. How do I know if they were complied with when I had both alignments done?
Each and every service was done at the same Toyota Dealer...

Thanks,

Tony
