Hey everyone, I am new here and had a question about my 2018 Cummins 6.7L.
I recently tuned and deleted my truck with MM3 tuner.
The MM3 monitor part does not turn on when I start my truck, if I touch the screen it asks me to agree or not agree with the terms.
I hit agree and all the gauges say N/A on them.
If I unplug the OBD port and plug it back in all my gauges read fine.
Every time I start my truck back up it it does the same thing every time.
If you guys have any help thank you guys!
