Monitors rear-door ajar switches, liftgate ajar switches, multifunction switches, multifunction headlight switch, ignition switch, PCI Bus, and
diagnostic tool. Based on input from these components, the BCM will send requests over the PCI Bus to have the Instrument Cluster perform
various chime operations.
The BCM has internal diagnostic capabilities that assist in diagnosing the vehicle's body system. When an "Open" or a "Short" circuit exists, the
diagnostic tool can read the stored BCM Diagnostic Trouble Codes (DTCs). The DTCs are very descriptive in identifying the appropriate feature that
has faulted.
Chime Warning System
The cluster monitors the PCI Bus for requests from various modules to display messages and under certain conditions sound a chime or series of chimes.
The chime system provides the Driver with warning chimes for the:
-

-
key-in accessory
-
engine temperature critical

The following list indicates the priority of the chime when more than one chime is active at the same time:
-
seat belt warning
-
door ajar
-
turn signal on
-

power liftgate
The cluster is responsible to set priority on all warning lamp announcement chimes.
CHIME ON CONDITIONS
The following is a list of the chime warnings and when they will sound.
Driver's Seat Belt Unbuckled:
There are two different Fasten Seat Belt Reminder announcements incorporated into the MIC's logic, a Non-enhanced announcement and an Enhanced
announcement.
When the Enhanced announcement is DISABLED, the Fasten Seat Belt Reminder operates as follows:
-
The BCM will request the MIC to chime five times and illuminate the Seat Belt Lamp after turning the ignition to the run/start position if the
driver seat belt is unbuckled.
When the Enhanced announcement is ENABLED, the Fasten Seat Belt Reminder operates as follows:
-
The BCM will request the MIC to chime continuously at a slow rate for a period of 6 seconds and illuminate the Seat Belt Lamp after turning the
ignition to the run/start position if the driver seat belt is unbuckled. After 6 seconds the chime will stop, but the Seat Belt Lamp will stay
illuminated. If the ignition is in the run position for a period greater than 70 seconds, and the driver seat belt is unbuckled, and the vehicle's
speed is greater than 5 mph (8 km/h) in a forward gear, the Enhanced Fasten Seat Belt Reminder will activate. This will cause the Seat Belt
Lamp to blink and a slow continuous chime to sound for 5 seconds. After 5 seconds, the chime will stop, but the lamp will remain illuminated for
