    Hi, I have a 2019 Freightliner Cascadia. With a Detroit DT12 engine. There is a yellow engine light on in the left side of the dashboard. No dash codes. Could this be DEF related? Or something else all together. See attached picture. Thank you.

    Is this kind of a joke?
    Your parking brake’s are engaged. There’s ’Park’ sign under it.

    Oh. I see. You’re talking about yellow one under tachometer, right?
    There’s menu with wrench symbol on dashboards screen. Use right and left buttons on the left side of the steering wheel to get there. It has diagnostics menu. Check what error is it.

    That's the MIL light. Can be on for just a low/high voltage for a light. The yellow with the check is the one to worry about.

    it is about your emissions system, there is a problem, check your def level. You do have an owners manual?
