Courtesy Lamp: Description and Operation
PRINCIPLES OF OPERATION
Interior Lighting
The generic electronic module (GEM) supplies voltage and ground to the interior courtesy lamps when any of the following inputs are received:
-
any door becomes ajar
-
liftgate or liftgate glass becomes ajar
-
remote keyless entry unlock signal is received
-
a key cylinder switch is turned to UNLOCK
All interior courtesy lamps are turned off when any of the following occurs:
-
all the doors, liftgate and liftgate glass are closed
-
the ignition switch is turned to RUN
-
a key cylinder switch is turned to LOCK
-
remote keyless entry lock signal is received
The illuminated entry feature is another feature which activates the interior lamps. This feature operates as follows:
The GEM illuminates the interior lamps at 80 percent brightness when an unlock signal is received from a remote keyless entry transmitter, key
cylinder switch, or door handle lifted when locked. If no door ajar signal is received the GEM will time out and 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 courtesy lamp control is not activated.
-
the ignition is in the RUN or START position and the interior lamp 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.
