Interior Lighting Control

The PZM provides the following interior lamp control:
^ Courtesy lamps.
^ Illuminated Entry Control of Courtesy Lamps.

Courtesy Lamps are enabled by the following inputs:
^ By discrete input to the PZM from the door jamb switches.
^ RFA transmitter activation (function of illuminated entry).
^ The left front or right front door has been unlocked using a key (function of Illuminated Entry).
^ Air Bag deployment.

The PZM only enables Illuminated Entry control of the courtesy lamps when the IPC twilight photocell indicates darkness via the serial data line to the PZM.
