DESCRIPTION AND OPERATION
INTRODUCTION
The courtesy lamp system is powered at all times
by the 10 amp fuse located in the Power Distribution
Center (PDC). The M1 circuit feeds the courtesy
lamps, which include the trunk lamp, underhood
lamp, visor/vanity lamps, dome lamp, time delay
relay, and the glove box lamp.
HALO LAMP/TIME DELAY RELAY
The time delay relay is used to allow a time-ON
function for the ignition switch halo lamp. Power for
the relay is received on the M1 circuit from the 10
amp fuse located in the Power Distribution Center
(PDC). This is the Ignition-Off Draw (IOD) fuse and
HOT at all times.
When a door is OPENED, or the headlamp switch
is moved to the dome lamp position, a ground path is
provided for the relay on the M23 circuit. This ener-
gizes the relay, CLOSING the contacts. When the
relay contacts are CLOSED, power is provided
through the relay to the M50 circuit.
The M50 circuit supplies current to the ignition
switch lamp in the steering column. Ground for the
lamp is provided on the Z3 circuit. This circuit
splices with the glove box lamp, the ash receiver
lamp, and the PRNDL lamp. The Z3 circuit termi-
nates at the instrument panel left center support.
Circuit M23 is also spliced with the Remote Key-
less Entry (RKE) module and the time out relay
located in the fuse block.
TIME OUT RELAY
The time out relay is located in the fuse block and
is used to control the ground path for various interior
lamps. It will also turn the lamps OFF after a spec-
ified period of time, and works with the Remote Key-
less Entry (RKE) system for illuminated entry.
Cirucit M2 connects to the relay and supplied a
ground path through the door ajar switches.Circuit M1 is used to supply battery voltage to the
relay. This circuit is proteced by a 10 amp fuse
located in cavity 13 of the Power Distribution Center
(PDC).
Circuit M32 is connected from the relay to the var-
ious interior lamps and RKE module.
PRNDL (TRANSMISSION RANGE INDICATOR)
LAMP
The PRNDL lamp receives power on the E2 circuit
from the 4 amp fuse located in the fuse block in cav-
ity 12. The fuse receives power from the headlamp
switch. Circuit E2 also powers the ash receiver lamp.
When the headlamp switch is moved to the PARK
or ON position, current flows through the fuse to the
PRNDL lamp. The ground for the lamp is supplied
on the Z3 circuit, and terminates at the instrument
panel left center support. This circuit is also spliced
in with the ash receiver lamp, the ignition switch
lamp, and the glove box lamp.
VISOR/VANITY LAMPS
The visor/vanity lamps are case-grounded, and are
operated by a switch internal to the assembly. Power
for the lamps is on the M1 circuit from the Power
Distribution Center (PDC). When the operator opens
the cover, the switch CLOSES, completing a path to
ground illuminating the lamp.
DOME LAMP
The dome lamp receives power from the 10 amp
fuse located in the Power Distribution Center on the
M1 circuit. This circuit is HOT at all times and the
Ignition-Off Draw (IOD) fuse. The ground path for
the lamp is provided in two different ways.
One way is through the door ajar switches and the
time out relay. Circuit M2 connects to all the door
ajar switches from the time out relay. The switches
are case-grounded to the body. When a door is
OPENED, the plunger in the switch CLOSES, com-
pleting a path to ground.
PL8W - 44 INTERIOR LIGHTING 8W - 44 - 5
Downloaded from www.Manualslib.com manuals search engine The second ground path is through the headlamp
switch. Circuit M23 is spliced in with the time out
relay. When the operator turns the headlamp switch
to the dome lamp ON position, a ground path is pro-
vided through the switch on the Z1 circuit. This
ground terminates at the instrument panel left cen-
ter support.
On vehicles equipped with Remote Keyless Entry
(RKE) the M23 circuit is spliced to the RKE module.
This allows the lamp to be turned ON when a valid
signal is reveived by the RKE module from the trans-
mitter.
MAP/READING LAMPS
The map/reading lamps are powered by the M1 cir-
cuit from the Power Distribution Center (PDC). This
circuit is the Ignition-Off Draw circuit and protected
by a 10 amp fuse. The M1 circuit is spliced and pro-
vides power for the visor/vanity lamps, radio, power
mirrors, dome lamp, time delay relay, and other inte-
rior lamps.
Ground for the lamps is provided from two sources.
One is the Z3 circuit which is spliced in with the
glove box lamp and terminates at the instrument
panel left center support. The second ground is pro-
vided on circuit M23. This circuit is spliced in with
the time out relay so the lamps will turn ON when
any door is OPENED.
On vehicles equipped with Remote Keyless Entry
(RKE) the M23 circuit, which is the ground circuit
when a door is OPENED, is connected to the RKE
module. The module will provide a ground path for
the lamps with a valid signal from the transmitter.
GLOVE BOX LAMP
The glove box lamp receives power on the M1 cir-
cuit from the 10 amp fuse located in the Power Dis-
tribution Center (PDC). A switch, wired in series
after the lamp, CLOSES when the glove box door is
opened, and completes a path to ground on the Z3
circuit.
The Z3 circuit is spliced in with the ash receiver
lamp, PRNDL lamp, and the time delay relay. The Z3
circuit terminates at the instrument panel left center
support.
ASH RECEIVER LAMP
The ash receiver lamp receives power on the E2
circuit from the 4 amp fuse located in the fuse block
in cavity 12. The fuse receives power from the head-
lamp switch. Circuit E2, which is HOT at all times,
also powers the Transmission Range Indicator
(PRNDL) lamp.
When the headlamp switch is moved to the PARK
or ON position, current flows through the fuse to the
ash receiver lamp. The ground for the lamp is sup-
plied on the Z3 circuit, and terminates at the instru-
ment panel left center support. This circuit is also
spliced in with the PRNDL lamp, the ignition switch
lamp, and the glove box lamp.
UNDERHOOD LAMP
Power for the underhood lamp is supplied on cir-
cuit M1. This is the Ignition-Off Draw (IOD) circuit
and is protected by a 10 amp fuse located in the
Power Distribution Center (PDC).
When the hood is raised a ground path is com-
pleted through the mercury switch to a case ground
illuminating the lamp.
TRUNK LAMP
The trunk lamp uses a case-grounded switch
located on the trunk latch. The switch is normally
OPEN. When the deck lid is opened, the switch
CLOSES, completing a path to ground on circuit M4.
The M1 circuit provides power to the lamp, and is
HOT at all times.
HELPFUL INFORMATION
²Check the 10 amp fuse located in the Power Dis-
tribution Center (PDC) for the trunk lamp, under-
hood lamp, visor/vanity lamps, dome lamp, time
delay relay, and the glove box lamp.
²Check for a good ground at the instrument panel
left center support.
²Check the door switches for a good ground.
