I have looked at SE input. It is stable when doors just reopen on themselves. I had car running with doors working normally. Seemed every couple of minutes doors would fully open then close by themselves? I was looking into inputs when car open doors fully and then started to close an bit then reopen and continued to do this until I stop it with inspection. While watching car door board on top of elevator WD1 and WD2 would pulse on and off when this happens. This DMC has no selector just switches in the hatch if that would make any difference? I will check those other ideas Thanks!
