Warning Chimes

The Warnings and Alarms System sounds a chime to bring attention to one or more of several conditions. These conditions are: 1) the Light Switch is in HEAD or PARK and the Ignition Switch is not in RUN, BULB TEST or START; 2) the key is in the Ignition Switch and the LH Front Door is open; 3) the Driver's Seat Belt is unbuckled when the Ignition Switch is turned to RUN, BULB TEST or START; and 4) the vehicle has driven more than a half mile with a turn signal on.

IGNITION KEY CHIME

Voltage is applied at all times to terminal 32 of the Chime Module through the STOP Fuse. When the key is in the ignition and LH Front Door is open, terminal 33 of the Chime Module is grounded. This sounds the chime.

LIGHTS ON CHIME

When the Light Switch is in HEAD or PARK, voltage is applied through the TAIL Fuse and Light Switch to terminal 31 of the Chime Module. When the Ignition Switch is in RUN, BULB TEST, or START, voltage is applied through the INDIC Fuse to terminal 38 of the Chime Module. If these two voltages are sensed, the chime will not be sounded.

When the Ignition Switch is turned to LOCK, OFF, or ACCY; the INDIC Fuse loses voltage. The Chime Module senses the change. If voltage is available from the Light Switch, voltage from the STOP Fuse is applied to sound the chime. The chime can be turned off by turning the Light Switch to OFF.

FASTEN BELTS INDICATOR

The Fasten Belts Indicator is also controlled by the Chime Module. The indicator will light anytime the Ignition Switch is in RUN, BULB TEST or START and the Seat Belt is unbuckled. It will go out as soon as the Seat Belt is buckled.

SEAT BELT CHIME

With the Ignition Switch in RUN, BULB TEST or START, voltage is applied through the INDIC Fuse to terminal 38 of the Chime Module. With the LH Front Seat Belt unbuckled, terminal 35 of the Chime Module is grounded through the Safety Belt Switch. The Seat Belt chime sounds for 4 to 8 seconds. The FASTEN BELTS Indicator will go out and the chime will stop as soon as the Seat Belt is buckled.
