Like the vehicle showing you strange error messages and warning lights. If your Toyota Sienna shows the «Traction Control Off» error message on the dash and also lights up the check engine light and some other warning lights, you came to the right place. In short, your Toyota Sienna may say «Traction Control Off» and accompany this message with a check engine light in a number of cases such as battery problems, alternator issues, software glitches, and also electrical problems. But, in most cases, this is a complex problem that comes from a bunch of different issues in your Toyota van. First of all, you need to understand that the traction control function relies on many different sensors all over your vehicle.
