Chime/Buzzer - Operation
Chime Warning System
CHIME WARNING SYSTEM
The chime warning system operates on battery voltage received through a fuse in the Junction Block (JB) on a non switched fused B(+) circuit so that the
system may operate regardless of the ignition switch position. The chime warning system also monitors the ignition switch position so that some chime
features are functional only with the ignition switch in the ON position, while others are functional regardless of the ignition switch position.
The chime warning system provides an audible indication to the vehicle operator or occupants under the following conditions:
-
Airbag Indicator Warning - The instrument cluster, also known as the Cab Compartment Node (CCN) transducer generates one short chime
when the ignition switch is in the ON position, and an electronic message is received over the Controller Area Network (CAN) data bus from the
Occupant Restraint Controller (ORC) requesting airbag indicator illumination. This warning only occurs following completion of the airbag
indicator bulb test, and only occurs once during any ignition cycle.
-
Door Ajar Indicator Warning - The CCN transducer generates one short chime when the ignition switch is in the ON position, a hardwired input
is received indicating that the status of any door ajar switch has changed, and an electronic message is received over the CAN data bus indicating
that the vehicle is moving.
-
Electronic Stability Program/Brake Assist System Warning - The CCN transducer generates one short chime when the Electronic Stability
Program (ESP)/Brake Assist System (BAS) has been manually disabled by the vehicle operator using the ESP/BAS traction control switch on the
instrument panel.
-
Electronic Stability Program/Brake Assist System Fault Warning - The CCN transducer generates one short chime each time the Electronic
Stability Program (ESP)/Brake Assist System (BAS) indicator is illuminated in the instrument cluster. This warning indicates a failure condition
has been monitored affecting the operation of the ESP/BAS related components or circuits. This warning only occurs following completion of the
ESP/BAS indicator bulb test, and only occurs once during any ignition cycle.
-
Electronic Vehicle Information Center Data Reset - The CCN transducer generates one short chime when the ignition switch is in the ON
position, and an electronic message is received over the CAN data bus from the optional Electronic Vehicle Information Center (EVIC) requesting
that the EVIC average fuel economy, trip odometer, distance to empty or customer programmable features data be reset. The EVIC monitors
hardwired inputs from the EVIC control push button switches to determine the proper reset messages to send to the CCN.
-
Fasten Seat Belt Indicator Warning- The CCN transducer repetitive chimes at a slow rate to announce that a hardwired input from the seatbelt
switch indicates that the driver side front seat belt is not fastened with the ignition switch in the ON position. The chime warning system also
supports the enhanced seatbelt reminder (beltminder) when this feature is enabled. See: Seat Belt Reminder Lamp/Description and Operation/Seat
Belt Warning Lamp - Operation.
-
Gate Ajar Indicator Warning - The CCN transducer generates one short chime when the ignition switch is in the ON position, a hardwired input
is received indicating that the status of the liftgate ajar switch has changed, and an electronic message is received over the CAN data bus indicating
that the vehicle is moving.
-
Head/Park Lamps-On Warning - The CCN transducer will generate repetitive chimes at a fast rate to indicate that hard wired inputs from the
driver door ajar switch, the headlamp switch, and the ignition switch indicate that the exterior lamps are turned on with the driver side front door
opened and the ignition switch in the OFF position. The chimes continues to sound until the exterior lamps are turned off, the driver side front
door is closed, or the ignition switch is turned to the ON position, whichever occurs first.
-
Key-In-Ignition Warning - The CCN transducer generates repetitive chimes at a fast rate to indicate that hardwired inputs from the driver door
ajar switch, the ignition switch, and the key-in ignition switch circuitry of the ignition switch indicate that the key is in the ignition lock cylinder
with the driver side front door open and the ignition switch in the OFF position. The chimes continues to sound until the key is removed from the
ignition lock cylinder, the driver side front door is closed, or the ignition switch is turned to the ON position, whichever occurs first.
-
Low Fuel Indicator Warning - The CCN transducer generates one short chime when the low fuel indicator is illuminated by the instrument
cluster circuitry. This chime only occurs once during any ignition cycle.
-
Low Wash Indicator Warning - The CCN transducer generates one short chime when the low washer fluid indicator is illuminated by the
instrument cluster circuitry. This chime only occurs once during any ignition cycle.
-
Overspeed Warning - The CCN transducer generates repetitive chimes at a slow rate to indicate that the vehicle speed is over a pre-programmed
speed value. The CCN monitors electronic vehicle speed messages received over the CAN data bus. This feature is only enabled on a CCN that
has been programmed with a Middle East Gulf Coast Country (GCC) country code.
-
Park Brake Reminder - The CCN transducer generates one short chime to announce that the hardwired input from the park brake switch and an
electronic vehicle speed message received over the CAN data bus indicate that the park brake is applied and the vehicle is moving. This chime
repeats each time the input conditions are met.
-
Sentry Key Customer Learn Mode Announcement - The CCN transducer generates one short chime to confirm that an electronic Customer
Learn mode message has been received over the CAN data bus to indicate that the Sentry Key REmote Entry Module (SKREEM) is prepared for
programming additional sentry key transponders. This chime feature is only active on vehicles equipped with the optional Sentry Key system, and
sold in a market where Customer Learn programming is an allowed feature.
-
Transmission Overtemp Indicator Warning- The CCN transducer generates repetitive chimes at a slow rate when the transmission overtemp
indicator is illuminated by the instrument cluster circuitry for a high or critical transmission fluid temperature condition. This chime repeats each
time the trans overtemp indicator is cycled from off to on.
-
Turn Signal/Hazard Warning Flasher Emulation - The CCN relay generates repetitive clicks at a slow rate to emulate an electromechanical
