The voltage does update when the program upload is in progress—I can see the voltage droop on the digital dash when the fans kick on to start the process, and can watch it creep back up once they kick out.
Also, your issue with those lights and the hatch isn’t the CCM—it doesn’t control the hatch or the PKE light. Both of those are controlled by the PKE module which is connected to the CCM but separate. I would suspect that as faulty first unless you have other non-PKE things going on.
