over all of the vehicle’s courtesy lamps except for the
driver and passenger front courtesy lamps. The
Driver Door Module (DDM) and the Passenger Door
Module (PDM) turn these lamps on based on
requests sent over the PCI Bus from the BCM. The
courtesy lamps will illuminate if:

• Any door is ajar and the courtesy lamp switch

on the headlamp switch is not in the dome OFF posi-
tion.

• The courtesy lamp switch on the headlamp

switch is in the dome ON position.

• A Remote Keyless Entry unlock message is

received.

• The operator unlocks the driver door with the

key (with VTSS only).

ILLUMINATED ENTRY

Illuminated entry will be initiated when the cus-

tomer enters the vehicle by unlocking the doors with
the key fob, or with the key if the vehicle is equipped
with vehicle theft security. Upon exiting the vehicle,
if the lock button is pressed with a door open, illumi-
nated entry will cancel when the door closes. If the
doors are closed and the ignition switch is turned
ON, the illuminated entry also cancels. The illumi-
nated entry feature will not operate if the courtesy
lamp switch is in the dome OFF position.

INTERIOR LIGHTING BATTERY SAVER

If any of the interior lamps are left ON after the

ignition is turned OFF, the BCM will turn them OFF
after fifteen minutes. To return to normal operation,
the courtesy lamps will operate after the dome lamp
switch or door ajar switch changes state. The reading
lamps and glove box lamp operate under the same
conditions as the courtesy lamps.
