Audible Warnings/Indicators

Safety Belt Warning Buzzer

With the Ignition Switch in START or RUN, voltage is supplied to the Audio Alarm Module (buzzer or chime) through the GAGES Fuse and the PNK/BLK (39) wire. When the Ignition Switch is first turned to START or RUN, voltage from the Audio Alarm Module is supplied to the Fasten Safety Belt Indicator in the instrument cluster through the YEL (237) wire. The indicator stays lit for about five seconds.
If the driver's safety belt is not buckled, a ground is applied to the Audio Alarm Module through the WHT (238) wire from the Safety Belt Retractor Switch. The chime or buzzer will sound for about five seconds.

Key-In Warning Buzzer

Voltage is supplied at all times to the Audio Alarm Module through the STOP-HAZ Fuse and the ORN (140) wire. With the key in the Ignition Switch and the Ignition Switch in ACC, LOCK or OFF, the chime or buzzer will sound if the left door is open.
With the door open, the LH Door Jamb Switch closes to ground. This provides a ground to the Audio Alarm Module through the TAN (158) wire, the Key-In Ignition Switch and the LT GRN (80) wire. The chime or buzzer will sound as long as the door is open or the key is in the Ignition Switch.

Lamps-On Warning Buzzer

When the Light Switch is in HEAD or PARK, and the Panel Dimmer Switch is not at the dimmest setting, voltage is applied through the PANEL LPS Fuse to the Audio Alarm Module through the GRA (8) wire. With the Panel Dimmer Switch at its dimmest setting, the current to the Audio Alarm module may not be enough to be sensed by the module. When the Ignition Switch is turned to RUN or START, voltage is supplied through the GAGES Fuse to the Module through the PNK/BLK (39) wire. These two voltages are sensed and the alarm is not sounded.
When the Ignition Switch is turned to LOCK, OFF or ACC, the GAGES Fuse loses voltage. The Audio Alarm Module senses the change. If voltage is still available from the PANEL LPS Fuse, voltage from the STOP-HAZ Fuse is supplied to sound the alarm through the ORN (140) wire. The alarm can be turned off by turning the Light Switch off. The Module no longer senses voltage from the Light Switch, so the alarm does not sound.
