The generic electronic module (GEM) supplies voltage and ground to the courtesy lights when any of the following inputs are received:
•  Any door is opened
•  Liftgate or liftgate glass is opened
•  Keyless entry unlock signal is received
•  Key cylinder switch turned to unlock
The courtesy lights are turned off when any of the following conditions exist:
•  All the doors, liftgate, and liftgate glass are closed.
•  The ignition switch is turned to the ON position.
•  The key cylinder switches are turned to lock.
•  A keyless entry lock signal received.
The illuminated entry feature is a separate function which also activates the interior lights. It functions as follows:
The GEM illuminates the interior lights at 80 percent brightness when an unlock signal is received from a keyless entry transmitter or key cylinder switch, or a door handle is lifted when locked. If no door opened signal is received, the GEM will turn the interior lights off. The illuminated entry feature will be canceled when any of the following conditions are met:
•  The remote transmitter lock button is pressed and the map/interior light control is not activated.
•  The ignition switch is at the ON or START position and the map/interior light control is not activated.

Battery Saver

The GEM is equipped with a battery saver which will turn the lights off after 45 minutes of inactivity. This feature is an internal function of the GEM software.
