    I just got a PM done on my 2020 Cascadia and after driving about 100 miles the check engine light came on. When I checked the diagnosis it’s giving me a ACM code 3223 and 520363 ATS electrical system problem detected. What could be causing it and is it safe to drive to my next location until I get it fixed?

    Google those and use the search block at the top right.
    Then ask again if needed.

    Bad NOX sensor. Had this code, you will get more codes soon.
