8U - 2 CHIME WARNING/REMINDER SYSTEMNS/GS
DIAGNOSIS AND TESTING (Continued)

SEAT BELT CHIME
The seat belt chime will sound for 4 to 8 seconds,
when the ignition is turned on and the driver's seat
belt is not buckled (seat belt switch is closed to
ground). This is a reminder to the driver to buckle
the seat belt. The seat belt lamp is controlled by the
mechanical instrument cluster. The cluster will also
illuminate the seat belt warning lamp for 6 seconds.
Buckling the driver's seat belt before the time out
has expired will cause the chime to stop immediately.
Chime rate: 38 to 62 chimes per minute.
To test the seat belt warning system, the ignition
switch must be in the OFF position for 1 minute
before starting the test. Turn the ignition switch to
the on position with the driver's seat belt not buck-
led. The seat belt warning lamp should light and the
chime should sound 4 to 8 seconds.
SEAT BELT LAMP
The seat belt lamp in the instrument cluster sig-
nals the vehicle passengers to fasten their seat belts.
The seat belt lamp is illuminated directly by the
instrument cluster for 6 seconds after the instrument
cluster receives the message from the Body Control
Module. The seat belt lamp is therefore illuminated
for 6 seconds whenever the ignition switch is moved
to run/start position.
(1) While ignition is off, the seat belt lamp will not
be illuminated.
(2) The ignition power feed status will be updated
every 250 milliseconds or on change.
(3) This lamp will be checked by the instrument
cluster for 6 seconds with every run/start cycle of the
ignition switch.
TURN SIGNAL ON CHIME
The turn signal on chime will warn the driver that
the turn signals have been left on. When the Body
Control Module receives a turn signal input for 1.6
km (1.0 miles), vehicle speed is greater than 24 km/h
(15 mph), the chime will sound continuously until the
turn signal is turned OFF. If vehicle speed drops
below 24 km/h (15 mph) prior to the warning being
activated, the accumulated distance traveled will be
reset. The turn signal chime is not activated whenthe emergency flashers are turned on. This feature
can also be disabled in EEPROM. Chime rate: 38 to
62 chimes per minute.
For the turn signal warning system to operate:
²Must have input from either the right or left
turn signal lamps. Creates a voltage change between
0 and battery voltage.
²The vehicle speed sensor sends a message to the
Powertrain Control Module that vehicle has exceeded
24 km/h (15 mph) for 1.6 km (1.0 miles).
²When the above two conditions are met, the
chime will sound. The chime will stop when no fur-
ther voltage change is detected.
²If hazard warning signals are pulsing, no chime
will sound.
²If speed drops below 24 km/h (15 mph) before
the warning is issued, the warning will not be issued
and the distance counter will be reset.
²If turn signal lamps are not working properly,
the chime will not sound.
²When using the scan tool, refer to the proper
Body Diagnostic Manual for the procedure.
WARNING LAMP ANNOUNCEMENT CHIME
The warning lamp announcement chime will warn
the driver to scan the instrument cluster to observe
which warning lamp is illuminated. Whenever the
volts, low fuel, low washer fluid, coolant level (gas/
diesel), low coolant level, engine temperature high
(diesel only), door ajar or gate ajar lamps are first
illuminated, the chime will sound one tone. The door/
liftgate ajar warning lamp announcement chime
sounds only if the vehicle speed is above 2 m.p.h.
Two seconds after ignition switch is turned ON or
until the seat belt warning chime ends, all warning
announcement chimes will be consolidated into one
warning announcement. This will occur 2 seconds
after the seat belt warning chime ends. If a warning
announcement should occur while another warning
chime in progress (turn signal, low oil pressure or
high speed warnings), no additional chimes will
sound after the chime in progress ends. All associ-
ated lamps will be illuminated, and the active chime
will be the warning announcement.
