I have a 2020 ram ecodiesel and I had a code for lower active grille shutter checked out wires and connection and saw nothing wrong. The truck sat for a week while on vacation and when I came back and started it for work light was on. Was told I had a bad grille shutter lower. Do I replaced and can't get the check engine light off. Keep getting a message on my topdon scanner that I need a ID and password for Gateway security Module. I have purchased a couple of bypass tools but still no luck. Please help

I believe somebody did a makeshift delete of this on YouTube.

The shutters themselves are plastic but there is a control motor on the bottom that some how knows if they are opening and closing, I would suspect that first.
