    We have a brand new 2013 Mack Granite and the check engine light came on while the truck was idling for about 10 minutes

    does anyone know how to turn off without using JBUS and tech computer? Is there a way without computer?

    What code are you getting on the dash? You can't just turn the light off, it will go out when the problem is fixed. Isn't it still under warranty?
