Combination Buzzer........................ 1
Courtesy Lamps and Dome Lamps............. 1
Diagram Index............................ 2General Information........................ 1
Transmission Range Lamp................... 1
Underhood Lamp.......................... 1
GENERAL INFORMATION
Circuit M1 supplies power to the underhood lamp,
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.
Circuit G10 from the buzzer connects to the seat
belt switch. When the seat belt is unlatched, the seat
belt switch closes providing ground on circuit Z1.
Circuit Z1 also grounds the combination buzzer
module.
HELPFUL INFORMATION
²Circuit F32 also powers the stop lamp switch.
²Circuit G5 also provides power for the instrument
cluster gauges and warning lamps, heated rear win-
dow relay and A/C compressor clutch relay. On Cana-
