DESCRIPTION AND OPERATION
INTRODUCTION
The interior lamps system is powered at all times
by the 10 amp fuse located in cavity 5 of the junction
block. This is the Ignition-Off Draw (IOD) fuse. Cir-
cuit M1 is connected from the fuse to the trunk lamp,
vanity lamps, dome lamp, and overhead lamps.
Power for the fuse is supplied on circuit A7 from
the Power Distribution Center (PDC). The A7 circuit
is protected by a 20 amp fuse located in cavity 4 of
the PDC.
DIMMER CONTROL
The dimmer control is used to control the intensity
of the instrument panel lamps. It is located in the
left multi-function switch. Power for the control is
supplied from the L7 circuit, which is the feed for the
parking lamps. This circuit is HOT when the parking
lamp switch is in the ON position. Ground for the
control is provided on the Z1 circuit which termi-
nates at the instrument panel left side cowl.
The control uses a variable resistor and is con-
nected to circuit E19. Circuit E19 connects to the
Body Control Module (BCM). When the operator
moves the control, resistance in the circuit changes
and the signal sent to the BCM changes. With the
change is resistance the BCM sends a signal over the
CCD Bus to the instrument panel changing the lamp
intensity.
For the other lamps the E2 circuit is connected
from the BCM to the lamps. The operation of these
lamps is the same as the instrument cluster lamps.
ILLUMNATED ENTRY
The illuminated entry relay located in the junction
block is used to control the ground path for the inte-
rior lamps. Power for the relay is supplied on circuit
M1. This is the Ignition-Off Draw (IOD) circuit and
is protected by a 10 amp fuse located in cavity 5 of
the junction block.

Ground for the relay is supplied on circuit M112.
This circuit connects from the relay to the Body Con-
trol Module (BCM). When the BCM provides a
ground path for the relay, circuits M2 and Z1 are
connected illuminating the interior lamps.
IGNITION KEY HALO LAMP
The Body Control Module (BCM) controls the oper-
ation of the halo lamp upon vehicle entry. When the
drivers door is OPENED the door ajar switch
CLOSES and circuit G75 is grounded. The BCM sees
that the door is ajar and provides a ground path for
circuit M50 from the lamp. Power for the lamp is
provided on circuit M1. This is the Ignition-Off Draw
(IOD) circuit and is protected by a 10 amp fuse
located in cavity 5 of the junction block.
VISOR/VANITY LAMPS
The visor/vanity lamps are operated by a switch
internal to the assembly. Power for the lamps is pro-
vided by circuit M1. The M1 circuit is spliced and
provides power to both lamps and is HOT at all
times.
When the operator lifts the cover on the lamp, the
switch CLOSES, completing a path to ground on cir-
cuit Z1. This circuit terminates at the instrument
panel left side cowl after passing through the ground
joint in the junction block.
On vehicles equipped with the optional garage door
opener the ground circuit is changed from Z1 to G38.
The G38 circuit connects from the lamps to the Body
Control Module (BCM). This input to the BCM allows
for a garage door opener lock-out feature.
COURTESY LAMPS
The door and rear floor courtesy lamps are pow-
ered by a 10 amp fuse located in cavity 5 of the junc-
tion block. This is the Ignition-Off Draw (IOD) fuse
and HOT at all times. Circuit M1 connects from the
fuse to the lamps.
