Wake-Up/Asleep States

"Wake-ups" are signals that will turn the PZM on and cause it to begin active control and/or monitoring. The PZM is "Asleep" when it has stopped controlling or monitoring and has become idle again. The PZM Wake-ups are:
^ Key in Door Lock Switch
^ Door Ajar Switches
^ Power Door Lock Switches
^ Trunk Ajar Switch
^ Trunk Tamper Switch
^ Ignition "ON"
^ Ignition "ACC"
^ Any Class 2 communication requiring PZM interaction
