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?
