I did your test and it did not change the state of pin 16 and the windows do not go down anymore. That is why I am now confused. For shakes I just got done doing your sync process 5 times again, but I have just a beeping machine.
Getting frustrated.
All the sensors are passing on the DRBIII sensor except for the trunk latch and nothing seems to clear it. Acts like it does not exist.

Right now I am waiting for TightAuto, but it might not be until fall based on his schedule.
