Have you ever wondered why sometimes the trac off light would just come on without any reasoning whatsoever?

Well my car throws a check engine light if I drive on the highway long enough. But before it throws the CEL, the trac off light comes on.

I checked with my code reader and my suspicion came true. The "TRAC OFF" light comes on because there is a code pending in the car's computer. What this mean is that the conditions are there for it to throw turn on the CEL light. Eventually, if the fault exists, the CEL light will turn.
