Audible Warning Device: Description and Operation
CIRCUIT OPERATION
Ignition Key Warning Alarm
Battery voltage is applied through the tail dome Fuse at all times to the ignition key warning switch. When the ignition key is inserted into the
ignition lock cylinder, the ignition key warning switch is closed, and a voltage signal is provided to the audio alarm module. If the LH door is
opened, the LH door jamb switch closes and a ground signal is provided to the audio alarm module. When these two signals are received
simultaneously, the audio alarm module activates the ignition key warning alarm.
Seat Belt Indicator
The audio alarm module receives battery voltage through the IG-COIL METER Fuse whenever the ignition switch is in the "ON" or "START"
position. If the driver's seat belt is not buckled, a ground signal is provided to the audio alarm module through the seat belt switch to G402. When
the module receives an ignition ON signal indicating that the ignition switch is in "ON" or "START," and the seat belt switch is closed
simultaneously, the audio alarm module provides a ground for the Seat Belt Indicator, which receives battery voltage from the IG-COIL METER
Fuse.
Headlight Warning Alarm
Battery voltage is applied at all times from the tail dome Fuse to the combination switch. If the Headlight Switch is closed, voltage is applied to the
audio alarm module. A voltage signal is also received by the audio alarm module from the IG-COIL METER Fuse if the ignition switch is in "ON"
or "START." If the audio alarm module sees the ignition signal go from "ON" to "OFF" while receiving a lights ON signal, it sounds the headlight
alarm.
