    Hey, we have a 2015 Cascadia that has not been cranking and has Red DEF light and message saying Must be in Neutral to Start Engine. Any ideas as to what can be wrong?

    PT CAN communication fault. Possibly CPC failure. It sounds like the ACM and TCM aren't communicating with the ICU or MCM.

    Did you turn the truck off while it was in gear? When you turn the key on can you hear the trans. going thru the gears like it does before starting the eng>
