ILLUMINATED ENTRY SYSTEM SERVICE
INFORMATION

The Illuminated Entry System is activated by the
system relay. The relay is located in the relay center
behind instrument panel. The relay receives input
from door pillar switches, the keyless entry system,
and the ignition switch (when in the RUN position).
When input is received, the timer in the relay imme-
diately begins the timing-out process. The timing-out
process requires approximately 30 seconds. Interior
lamps are turned off either when the 30 second time-
out is completed or when the ignition switch is
turned ON. If a door remains open for more than 30
seconds, the interior lamps will stay on until the door
is closed.
The illuminated entry system also operates
when a door is opened to exit vehicle. When
door is closed the lamps will stay on for re-
maining portion of the 30 seconds.

GENERAL INFORMATION
Circuit A4 from fuse 1 in the Power Distribution
Center (PDC) powers circuit M1 through the Ignition
Off Draw (IOD) fuse in cavity 5 of the fuse block. Cir-
cuit M1 supplies power to the interior lamps. A stand
alone branch of circuit M1 connects directly to fuse 1
in the PDC and the underhood lamp.
Circuit M1 also connects to the coil side of the illu-
minated entry relay. The Remote Keyless Entry
(RKE) module controls the illuminated entry relay.
Circuit E2 from the dimming module supplies
power for the instrument panel illumination lamps.

DIMMING MODULE
Circuit 352 from fuse 24 in the fuse block powers
the dimming module. Circuit L90 from the headlamp
switch feeds circuit 352 through fuse 24 when the
headlamp switch is in the PARK, LOW, or LOW/FOG
position. Circuit 366 from fuse 12 in the fuse block
supplies power to the headlamp switch for circuit
L90. Circuit A6 from fuse 10 in the Power Distribu-
tion Center powers circuit 366 through fuse 12.
Circuit 52 from dimming switch connects to the
dimming module. The dimming module determines
the level of illumination selected from the input it re-
ceives on circuit 52.
The dimming module powers the illumination
lamps on circuit E2. Circuit E2 splices to supply
power to the following illumination lamps:
• Ash receiver lamp
• Cigar lighter lamp
• Headlamp switch lamps
• Radio lamp
• Instrument cluster general illumination lamps
• A/C-Heater control switch lamp
• Transmission range indicator lamp
• Transfer case range indicator lamp
• Heated rear window switch lamp
• Overdrive switch lamp
• Graphic display module illumination lamps
• Automatic temperature controls lamp
• Overhead console illumination lamp

Circuit Z1 provides ground for all of the illumina-
tion lamps except for the automatic temperature con-
trols lamp and A/C-Heater switch lamp. Circuit Z4
provides ground for the automatic temperature con-
trols lamp. The A/C-Heater switch lamp is case
grounded.
Additionally, the headlamp switch lamps also
ground when the courtesy lamp switch is closed.
When closed, the courtesy lamp switch connects the
headlamp switch lamps to circuit M2.

HELPFUL INFORMATION
• On vehicles built for sale in Canada, the dimming
module is part of the Daytime Running Lamps (DRL)
module.

INTERIOR LAMPS
Circuit A4 from fuse 1 in the Power Distribution
Center (PDC) powers circuit M1 through the Ignition
Off Draw (IOD) fuse in cavity 5 of the fuse block. Cir-
cuit M1 supplies power to the:
• Cargo lamp
• Dome/reading lamps
• Key-in lamp
• Left courtesy lamp
• Left door courtesy lamp
• Overhead console lamps
• Right courtesy lamp
• Right door courtesy lamp
Circuit M2 connects all of the above interior lamps
to circuit Z1 through either one of the door jamb
switches, liftgate switch, or liftgate glass ajar switch.
With the vehicle not moving, when either the liftgate,
liftgate glass or one of doors opens, these switches
close connect circuits M2 and Z1. Circuit Z1 provides
ground for the lamps.
If the vehicle is equipped with Remote Keyless En-
try, the illuminated entry relay connects circuit M2
to ground on circuit M1.
Circuit Z1 also connects directly to the switches for
the dome/reading lamps or if equipped, overhead con-
sole lamps.
