Rear Access Open on SUT

[CG07SUT]

I've had this happen a couple of times. I usually try to close the mid-gate from the driver's side. When this happened, I went to the passenger side, pressed the button to open the gate, dropped the gate then re-shut the gate from the passenger side. This cleared the message and allowed the windo to go up. You may need to slam the gate shut, but it has always cleared for me.
