Hi, I have a car that when keyed to phase 1 runs floor to floor like it’s lost. My rotary switches for main and alternate and others all check out ok. When I go into F5 though both parameters 23 and 26 read back 00 meaning top floor. I checked the other simplex which does work, and it has the same feedback in F5. I’m wondering if that’s just a feature of this generation and if there’s any way to tell if maybe that rotary switch is bad. J and M if I remember correctly.
