Audible Warning Device: Description and Operation
Seat Belt Warning Alarm
The Seat Belt Warning Alarm (approximately 1 pulse per half second) is activated when the following conditions are met simultaneously: Ignition
Switch in the "ON" position and the LH Front Seat Belt unbuckled. The Audio Alarm Module applies and monitors battery voltage across a fixed
resistor to the Seat Belt Switch. When the LH Front Seat Belt is unbuckled, the voltage being monitored at the Audio Alarm Module is high, thus
indicating that the LH Front Seat Belt is unbuckled. The alarm will sound for six seconds if the LH Front Seat Belt is not buckled. If at any time, the LH
Front Seat Belt is buckled while the Audio Alarm Module is sounding, the alarm will stop.
The Seat Belt Indicator works in conjunction with the Seat Belt Warning Alarm The Seat Belt Indicator is supplied ignition voltage through the IG Fuse.
If the LH Front Seat Belt is unbuckled, then ground is applied from G400 through the closed contacts of the Seat Belt Switch to the Seat Belt Indicator.
The Seat Belt Indicator will remain lit until the LH Front Seat Belt is fastened.
