Audible Warning Device: Component Tests and General Diagnostics
The Chevrolet Warning Alarm generates audible warnings for three conditions: Headlamps "ON" warning, ignition Key Warning, and Fasten Belts
Warning. Buick, Olds and Pontiac add a fourth warning for Turn Signals "ON." The Headlamps "ON" Warning and Signal Warning are pulsed
approximately once every one half second, sounding the quickest. The Ignition Key Warning is pulsed once every second. The Fasten Belts Warning is
a continuous tone.
Headlamps "ON" Warning
When the Headlamp Switch is in "PARK" or "HEAD,"voltage is applied to the Lamps "ON" Input of the Warning Alarm. When the Ignition
Switch is turned out of the "RUN" position, voltage is removed from the Ignition Switch Input of the Warning Alarm. When voltage is present at
the Lamps "ON" Input and no voltage applied to the Ignition Switch Input, the Warning Alarm will sound the Lamps "ON" Warning.
Ignition Key Warning
The Warning Alarm applies voltage at all times to the Ignition Key Warning Switch. When the Ignition Key is placed into the Ignition Switch, the
Ignition Key Warning Switch is closed. When the LH front door is open, the LH Front Door Ajar Switch (Chevy) or Left Front Door Jamb Switch
(B,O,P) closes the circuit to ground. The Warning Alarm senses a voltage drop at the Ignition Key Input and will sound the Ignition Key Warning.
Fasten Belts Warning
The Warning Alarm applies voltage to the Seat Belt Switch at all times. The Warning Alarm senses a voltage drop at the Seat Belt Input through
the closed contacts of the Seat Belt Switch when the driver's seat belt is unlatched. When the driver's seat belt is latched, the Seat Belt Switch is
opened and the Warning Alarm senses voltage at the Seat Belt Input. when the Ignition Switch is turned to "RUN," voltage is applied to the
Warning Alarm Ignition Switch Input. When voltage is present at the Ignition Switch Input and 0 volts at the Seat Belt Input, the Warning Alarm
will sound the Fasten Belts Warning for 4 to 8 seconds. If voltage is present at the Ignition Switch Input and the Seat Belt Input, the Warning
Alarm will disable the Fasten Belts Warning.
Turn Signal Warning Chime
When a turn signal is operate, voltage is alternately applied and removed to Warning Alarm Connector C2, terminal "A". The module begins to
monitor vehicle distance at Connector C2, terminal "B". If the Turn Signal is still flashing after the vehicle has traveled 0.8 kilometers (0.5 miles),
the Turn Signal Warning chime will sound.
