CHIME SYSTEMS
The Chime System is an integral part of the Body Control Module (BCM) and provides the driver with two types of chimes, Warning and
Announcement. The BCM monitors its hardwired inputs and CCD bus messages to determine when a chime is needed. The Warning Chimes are a
dual tone chime for the following conditions: Seat Belt Unbuckled, Exterior Lamps On, Key-In Ignition, Critical tire pressure, and Dome Lamps
On. The Announcement Chime is a single tone chime to warn the driver when an instrument cluster gauge is out of range or a warning lamp is on.
Refer to the General Information System Description and Functional Operation for more information on the Instrument Cluster gauges and
warning lamps.
During shipment (with the IOD fuse disconnected) the Warning and Announcement chimes will not work with the ignition key turned off.
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 BCM via the CCD bus. The cluster will
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, start with the ignition switch in the OFF position. Turn the ignition switch to the ON position with the driver's
seat belt not buckled. 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 signals the driver's to fasten the seat belt. The seat belt lamp is illuminated 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. While ignition is off, the seat belt lamp will not be illuminated. This lamp will be illuminated for 6
seconds with every run/start cycle of the ignition switch.
Chime rate: 50±12 chimes per minute.
EXTERIOR LAMPS ON CHIME
The exterior lamp on chime will warn the driver that the exterior lights have been left on.
With the ignition switch OFF:
-
Driver's door is open (door ajar switch is closed to ground)
-
Parking lamps or headlamps ON (parking lamp switch is closed to ground)
The chime will sound until lights are turned OFF, driver's door closed or until the battery protection time out of 3 minutes has expired.
Chime rate: 168 to 192 chimes per minute.
To test the exterior lamps left on function:
-
Turn ignition off
-
Remove ignition key
-
Turn exterior lamps on with driver's door open. Chime should sound until lamps are turned off or driver's door is closed.
KEY-IN IGNITION CHIME
The key-in ignition chime will act as a warning to the driver that the ignition key has been left in the ignition switch.
With the ignition switch is in the OFF position ONLY:
-
Driver's door is open/ajar (door ajar switch is closed to ground)
-
Key is in the ignition switch (key-in ignition switch is closed to ground)
