DESCRIPTION AND OPERATION
AIRBAG CONTROL MODULE (ACM)
Two different circuits supply battery voltage from
the fuse block to the Airbag Control Module (ACM),
F15 and F25. The F15 and F25 circuits are connected
to separate bus bars internal to the fuse block. Dif-
ferent circuits from the Power Distribution Center
(PDC) and ignition switch supply battery voltage to
the fuse block bus bars.
The F25 circuit supplies battery voltage to the
ACM only when the ignition switch is in the RUN
position. The F15 circuit powers the ACM when the
ignition switch is in either the START or RUN posi-
tion.
An internal bus bar in the ignition switch connects
the A1 circuit from the PDC to the A21 circuit when
the switch is either the START or RUN position. The
A21 circuit supplies battery voltage to the bus bar in
the fuse block that feeds the F15 circuit. A 30 amp
fuse in the PDC protects the A1 and A21 circuits. A
10 amp fuse in the fuse block, cavity 9, protects the
F15 circuit.
When the ignition switch is in the RUN position, it
connects the A2 circuit from the PDC to the A22 cir-
cuit. The A22 circuit supplies battery voltage to the
fuse block bus bar that feeds the F25 circuit. A 40
amp fuse in the PDC protects the A2 and A22 cir-
cuits. A 10 amp fuse in the fuse block, cavity 5, pro-
tects the F25 circuit.
Circuits D1 and D2 are connected to the CCD Bus
and the ACM. The CCD bus is used to provide com-
munications between modules and the universal data
link connector.
The ACM has a case ground and an external dedi-
cated ground, circuit Z6. The dedicated ground con-
nects to the instrument panel right center support.
AIRBAG IMPACT SENSOR
The Airbag system uses a sensor internal to the
Airbag Control Module (ACM) to detect impact. For
information regarding operation of this sensor, refer
to the appropriate group of the Service Manual.
AIRBAG SQUIB (AIRBAG IGNITER)
DRIVERS SIDE AIRBAG
Two circuits, R43 and R45, connect the ACM to the
drivers side airbag module squib (igniter) after pass-
ing through the clock spring connector. Circuit R43
from cavity 3 of the ACM 4-way connector connects
to the squib. Circuit R45 from cavity 4 of the ACM
4-way connector connects to the squib. R43 and R45
are a twisted pair of wires.
PASSENGERS SIDE AIRBAG
Two circuits, R42 and R44, connect the ACM to the
passengers side airbag module squib (igniter). Circuit
R42 from cavity 1 of the ACM 4-way connector con-
nects to the squib. Circuit R44 from cavity 2 of the
ACM 4- way connector connects to the squib. R42
and R44 are a twisted pair of wires.
Circuits R50 and R51 are connected from the ACM
to the passangers airbag. These circuits are used to
monitor the pressure switch.
AIRBAG WARNING LAMP
The Airbag Warning lamp is used to alert the oper-
ator of a problem with the Airbag system. The lamp
is illuminated when the Airbag Control Module
(ACM) grounds the R41 circuit. Refer to the appro-
priate section of the Service Manual or Diagnostic
Test Procedures Manual to diagnosis this system.
HELPFUL INFORMATION
²Check for blown fuses in the circuit that connect
to the ignition switch and those that connect to the
ACM.
²While the bus bars in the fuse block power the
ACM, they also feed additional components on sepa-
rate fuse protected circuits.
²The ACM has a case ground and an external
dedicated ground. The dedicated ground connects to
the instrument panel right center support.

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.

DESCRIPTION AND OPERATION
REAR WINDOW DEFOGGER
The Rear Window Defogger system is powered by a
40 amp fuse located in the Power Distribution Center
(PDC) on circuit A4. This circuit is HOT at all times.
The system is also powered by a 10 amp fuse located
in cavity 8 of the fuse block, this fuse is HOT in the
RUN position only.
When the operator presses the rear window defog-
ger switch the contacts internal to the switch CLOSE
and the timer starts. When the switch is released the
timer circuity keeps the relay energized for the spec-
ified time.
Voltage is passed through the switch on the A4 cir-
cuit to the C15 circuit and then to the rear window
defogger grid. The grid consists of two bus bars and
grid lines that form a parallel circuit. When voltage
is passed through the grid, the grid lines heat up and
heat the rear window.
Grounding for the rear window defogger switch is
provided on the Z2 circuit and terminates at the
instrument panel right center support. The grid uses
the grounding point at the rear body in the right
wheel house.
When the system is in operation, a L.E.D. located
in the switch, indicates to the operator the system is
functioning. The switch is also illuminated when the
headlamp switch is in the PARK or ON position.
Power for the illumination circuit comes from the 4
amp fuse, located in cavity 12 of the fuse block, on
the E2 circuit.
HELPFUL INFORMATION
