@slavie here's what I got after poking around, I so appreciate your thoughts and input. Actual values show power is flowing, however, I'm only able to change the value from "not actuated" to "actuated" when touching the driver side rear door. The rest are dead, leading me to suspect replacing the problem door handles is the solution.

I haven't been able to determine if just the proximity sensors in the handles can be replaced, or, if the whole handle has to be because it's one unit. And I still don't know if the dead handles are related to the the hazards flashing four times instead of their customary two. That would seem odd if truly correlated.

I didn't see anything missed in the adaptations menu – I changed the value to 3-button but that did nothing so I switched it back to what it was, 2-button. Was there anything else you suggested I troubleshoot?
