TRAC LIGHT ISSUE
The trac light does NOT come on for the smog test. It has noting to do with the smog test. The trac light DOES come on when the Check Engine light comes on, when a failure is detected. From what I remember, the trac light WILL come on if the smog is a "dyno-driven" smog test, but it has nothing to do with the test, the trac simply comes on because only one wheel is spinning, just like it will when you are spinning on ice.. Hope this helps.
