Audible Warning Device Control Module: Description and Operation
CIRCUIT OPERATION
The buzzer module sounds an audible warning tone. The tone sounds for seat belt warning and when the ignition key is in the ignition switch while
the drivers door is open. The tone also sounds when the ignition key is in the ON position while the drivers side seat belt is not buckled.
Fuses 7 and 16 in the fuse block protect the buzzer module. Fuse 7 powers circuit F32 which connects to the buzzer module. Circuit A3 from fuse
G in the Power Distribution Center (PDC) supplies power to the fuse block for fuse 7 and circuit F32.
Circuit G5 from fuse 16 in the fuse block also provides voltage to the buzzer module when the ignition switch is in the START or RUN positions.
The ignition switch connects circuit A1 from fuse C in the PDC to circuit A21. Circuit A21 connects to the fuse block.
When the parking lamps or headlamps are ON, the headlamp switch connects circuit G16 from the drivers side door jamb switch to circuit G26.
Circuit G26 connects to the buzzer module and the key-in switch. Circuit G16 from the drivers side door jamb switch also connects to the key-in
switch.
Circuit G13 from the buzzer powers the seat belt warning lamp in the instrument cluster. Circuit Z1 at the instrument cluster provides ground for
the lamp.
Circuit G1O from the buzzer connects to the seat belt switch. When the seat belt switch closes a path to ground is completed on circuit Z1.
Circuit Z1 also grounds the combination buzzer module.
