Chime Warning System
CHIME WARNING SYSTEM
The chime warning system operates on battery voltage received through a fuse in the Totally Integrated Power Module (TIPM) 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:
-
Door Ajar Warning - The ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) will generate one
short chime when the ignition switch is in the ON position and a door textual message is displayed in the odometer Vacuum Fluorescent Display
(VFD) unit, or when a DOOR AJAR textual message and icon is displayed in the optional Electronic Vehicle Information Center (EVIC)
reconfigurable display of the instrument cluster. This warning indicates that a door is, or multiple doors are not closed or completely latched.
When the vehicle is moving, and a door is left ajar, the door ajar lamp will illuminate, and an audible chime will be heard.
-
Fasten Seat Belt Indicator Warning - The EMIC/CCN transducer will generate repetitive chimes at a slow rate to announce that the seat belt
switches and the ignition switch indicate 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 seat belt reminder (beltminder) when this feature is enabled.See: Seat Belt Reminder Lamp/Description
and Operation/Operation.
-
Head/Park Lamps-On Warning - The EMIC/CCN transducer will generate continuous repetitive chimes to indicate that inputs from the
headlamp switch, the ignition switch and the driver side front door ajar switch indicate that the exterior lighting is turned ON with the ignition
switch in the OFF position and the driver side front door is open. The chimes will continue 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 EMIC/CCN transducer will generate continuous repetitive chimes to indicate that inputs from the ignition switch
and the driver side front door ajar switch indicate that the key is in the ignition lock cylinder with the ignition switch in the OFF position with the
driver side front door open. The chimes will continue 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.
-
Liftgate Ajar Warning - The EMIC/CCN transducer will generate one short chime when the ignition switch is in the ON position and a GATE
textual message is displayed in the odometer Vacuum Fluorescent Display (VFD) unit, or when a liftgate textual message and icon is displayed in
the optional Electronic Vehicle Information Center (EVIC) reconfigurable display of the instrument cluster. This warning indicates that the liftgate
is not closed or completely latched. When the vehicle is moving, and a door is left ajar, the liftgate ajar lamp will illuminate, and an audible chime
will be heard.
-
Overspeed Warning - The EMIC transducer will generate one short chime when the vehicle speed is over a pre-programmed speed value. This
feature is only enabled on vehicles that have been configured for sale in a Middle East Gulf Coast Country (GCC).
-
Park Brake Reminder - The Park Brake Reminder lamp will illuminate when the brake is on. As the vehicle starts moving and gains a speed ,
the EMIC/CCN transducer will generate one short chime when the brake/park brake indicator is illuminated to announce that the park brake is
applied or not fully released. This chime will repeat each time the input conditions are met.
-
Sentry Key Customer Learn Mode Announcement - The EMIC/CCN transducer will generate one short chime to confirm that the Sentry Key
electronic Customer Learn mode is active, which indicates that the Sentry Key Remote Entry Module/Wireless Control Module
(SKREEM/WCM) is prepared for programming additional Sentry Key transponders. This chime feature is only active on vehicles sold in a market
where Customer Learn programming is an allowed feature.
-
Turn Signal/Hazard Warning Flasher Emulation - The EMIC/CCN relay will generate repetitive clicks at a slow rate to emulate an
electromechanical flasher when the turn signal or hazard warning system are operating. The EMIC/CCN relay will generate repetitive clicks at a
fast rate to indicate that the right or left turn signals are operating with one or more bulbs ineffective. In either case, the clicks will continue until
the turn signal or hazard warning system is turned OFF.
-
Turn Signal On Warning - The EMIC/CCN transducer will generate one short chime to indicate that a turn signal has been active continuously
for 1.6 kilometers (1 mile) with the vehicle speed greater than 22 kilometers-per-hour (15 miles-per hour). Vehicles built for markets other than the
United States and Canada have a revised distance threshold of 4 kilometers (2.49 miles) for this feature. This chime will repeat each time the input
conditions are met. The hazard warning flashers will not activate this chime feature.
-
Warning Indicator Announcement - The EMIC/CCN transducer will generate one short chime each time the Malfunction Indicator Lamp
(MIL), low washer fluid indicator, oil change required indicator, Tire Pressure Monitor (TPM) indicator, Electronic Stability Program (ESP) OFF
indicator, gas cap indicator, Ignition-OFF Draw (IOD) fuse, low coolant indicator or certain other indicators are illuminated by the instrument
cluster circuitry. The MIL and certain other indicators may be illuminated when any critical vehicle systems are operating outside of their normal
or default parameters. The instrument cluster monitors electronic messages received over the CAN data bus to determine when to illuminate these
indicators.
The EMIC/CCN provides chime service for all available features in the chime warning system, except for the audible warning function provided by the
optional park assist system display module. The EMIC/CCN relies upon its internal programming, numerous hard wired inputs, and electronic message
inputs received from other modules over the Controller Area Network (CAN) and the Local Interface Network (LIN) data buses to provide the chime
warning system features. The internal programming of the EMIC/CCN determines the priority of each chime request input that is received, as well as the
