dome lamp, right courtesy lamp and left courtesy
lamp. Fuse 12 in the Power Distribution Center
(PDC) protects circuit M1. Circuit A4 from fuse 8 in
the PDC supplies voltage to fuse 12 and circuit M1.
Fuse 12 is referred to as the Ignition Off Draw (IOD)
fuse.
COURTESY LAMPS AND DOME LAMPS
Circuit M1 supplies battery voltage to the dome
lamps and the right and left courtesy lamps. Circuit
M2 provides ground for the lamps through either the
case grounded door jamb switches or through the
dimmer switch to circuit Z1.
In the ON position, the dimmer switch connects
circuit M2 to ground on circuit Z1. When a door
opens, the case grounded door jamb switch closes and
provides ground for the lamps on circuit M2.
HELPFUL INFORMATION
²Circuit M1 also supplies voltage for radio memory,
underhood lamp and the ABS data link connector.
UNDERHOOD LAMP
Circuit M1 supplies battery voltage for the under-
hood lamp. A mercury switch in series after the lamp
connects the lamp to ground on circuit Z1. When the
hood is raised, mercury inside the switch moves to a
position where it connects circuit M1 to circuit Z1, il-
luminating the lamp. The underhood lamp is wired
in parallel with other components on circuit M1.
ACCESSORY LAMP AND HEATER CONTROL PANEL
LAMP
Circuit E1 from the dimmer switch supplies bat-
tery voltage to fuse 10 in the fuse block when the
dimmer switch is in the LOW or ON position. Fuse
10 protects circuit E2 which supplies power to the
heater control panel lamp and the accessory lamp.
Circuit Z1 provides ground for each lamp.
TRANSMISSION RANGE LAMP
Circuit E1 from the dimmer switch supplies bat-
tery voltage to fuse 10 in the fuse block when thedimmer switch is in the LOW or ON positions. Fuse
10 protects circuit E2 which supplies power to the
transmission range lamp. The lamp is case grounded.
COMBINATION BUZZER
The combination buzzer module sounds an audible
warning tone. The tone sounds for seat belt warning
and when the key is in the ignition switch while the
drivers door is open. The tone also sounds when the
ignition switch is in the ON position while the driv-
ers side seat belt is not buckled. Refer to Group 8U
for buzzer operation.
Fuses 3 and 9 in the fuse block protect the combi-
nation buzzer. Fuse 3 powers circuit F32 which con-
nects to the buzzer. Circuit A6 from fuse 3 in the
Power Distribution Center (PDC) supplies power to
the fuse block for circuit F32.
Circuit G5 from fuse 9 also provides voltage to the
combination buzzer when the ignition switch is in
the START or RUN position. The ignition switch con-
nects circuit A1 from fuse 4 in the PDC to circuit
A21. Circuit A21 connects to the fuse block.
When the key-in switch closes, it connects circuit
G26 to circuit G16. Circuit G16 connects to the driv-
ers side door jamb switch. When the drivers side door
is open and the key-in switch is closed, the case
grounded door jamb switch closes and supplies
ground for the buzzer. Circuit G26 from the combina-
tion buzzer connects to the key-in switch.
Circuit G13 form the buzzer powers the seat belt
warning lamp in the instrument cluster. Circuit Z1
at the instrument cluster provides ground for the
lamp.

When the park lamp relay energizes, the relay con-
tacts close and connect circuit F81 from fuse 6 in the
fuse block to circuit L36. Circuit L36 connects to the
contact side of the high beam relay. The contacts in
the high beam relay are normally closed. Battery
voltage flows through high beam relay to the fog
lamps on circuit L39. Circuit L39 also splices to the
lamp in the fog lamp switch.
Circuit L3 from the dimmer switch provides power
for the high beams of the headlamps and connects to
Circuit G34. Circuit G34 powers the coil side of the
high beam relay. Circuit Z1 provides ground for the
coil. When the operator selects high beam operation
or flashes the optical horn, circuit G34 energizes the
high beam relay. When energized, the normally
closed contacts in the relay open, shutting off battery
voltage to the fog lamps on circuit L39.
HELPFUL INFORMATION
²Circuit A6 from fuse 3 in the PDC supplies voltage
to the fuse block for fuses in cavities 3 and 6. Fuse 6
in the fuse block protects circuit F81 which powers
the contact side of the park lamp relay.
²In the high beam position, the dimmer switch con-
nects circuit L20 from the headlamp switch to circuit
L3. The headlamp switch connects circuit A3 from
fuse 7 in the PDC with circuit L20. Circuits A3 and
L20 are HOT at all times.
DAYTIME RUNNING LAMP (DRL) MODULEÐ
CANADIAN VEHICLES ONLY
On Canadian vehicles, the low-beam headlamps op-
erate when the ignition switch is in the RUN position
and the headlamp switch is OFF.
When the ignition switch is in the START or RUN
positions, circuit A1 from fuse 4 in the Power Distri-
bution Center (PDC) connects to circuit A21. Circuit
A21 supplies voltage to circuit G5 through fuse 9 in
the fuse block. Circuit G5 splices to supply battery
voltage to the DRL module.
Circuit L20 from the headlamp switch connects to
the DRL module. Circuit L20 is HOT at all times.
The DRL module receives the vehicle speed sensor
input from circuit G7. Circuit G34 from the DRLmodule provides power for the high beam indicator
lamp in the instrument cluster.
Circuit L4 feeds the low beams of the headlamps.
When the headlamp switch is in the OFF position,
the DRL module powers the left and right headlamps
on circuit L4. When the headlamps are ON, the dim-
mer switch powers the low beams on circuit L4.
Circuit L3 feeds the high beams of the headlamps.
When the operator flashes the high beams with the
turn signal stalk, the DRL senses voltage on circuit
L3. When it senses voltage on circuit L3, the DRL
module stops supplying power to the low beams on
circuit L4.
Circuit Z1 provides ground for the DRL module.
Circuit Z1 terminates at the radiator left side sup-
port.
