"check engine" light

[Irving]

Did they just recently change the emission law that you CAN have a check engine light, or that you can not? I remember it used to be that as long as you passed, it didn't matter if a light was on or not.

I have had customers make it through with a check engine light, but not with a check engine and a ABS warning light. Have to have the ABS light off before it gets on the dyno.
