Interior Lighting Control

The Body Control Module (PZM) provides control for following interior lighting items:
^ The courtesy lamps
^ The illuminated entry control of the courtesy lamps

The following inputs enable the courtesy lamps:
^ The discrete input to the PZM from the door jamb switches
^ The RFA transmitter activation (a function of the illuminated entry system)
^ Using a key in order to unlock either front door (a function of the illuminated entry system)
^ The air bag deployment

The PZM only enables the illuminated entry control of the courtesy lamps when the instrument cluster twilight photocell indicates darkness.
