2023 Toyota Highlander Rear Power Door intermittent jam protection

Hello, 
I have a 23 Highlander that will intermittently the rear power door will close like normal latch then 2 seconds later unlatch and pop back open about 2 to 3 inches I am assuming this is what Toyota calls jam protection. I have tried reinitializing and no change I have determined my problem is the left touch sensor reading un-touched open and shut. I tested the contact switch 1kohm open and under 100Ohm closed that is within Toyota spec. I guess I feel dumb because I'm trying to understand what reading i should see at the module and what pins I should be testing at. I don't know what type of sensor this is and was hoping someone could describe the circuit to me I've attached the diagram
