We battled this for months on an HS with the WG operator. That auxiliary close limit was put right on the strike and it was one of those heavy duty plunger switches that are threaded so you can flex right to them. If the car is sitting with no demand (no squeeze) and it comes off that switch dropping SS info, it shuts down throwing that fault. In our case the spring tension of that switch was just too strong and assisted too much pushing the door back open a little bit. I could adjust everything and get it to work but a couple days later it would be doing it again. Long term solution was to replace that switch with a lever type micro switch.
