Wake-Up/Asleep States

The wake-ups are signals that turn ON the Body Control Module (PZM). The signals cause active control or monitoring by the PZM.

The PZM wake-ups can include the following signals:
^ The key in door lock switch
^ The door ajar switch
^ The power door lock switches
^ The trunk ajar switch
^ The trunk tamper switch
^ The cycling of the ignition switch
^ Any class 2 communication that requires interaction with the PZM
