The chime warning system provides an audible indication to the vehicle operator or occupants under the following
conditions:
-- Airbag Indicator Warning - The ElectroMechanical Instrument Cluster (EMIC) transducer will generate one
short chime when the ignition switch is in the On position, and an electronic message is received over the
Programmable Communications Interface (PCI) data bus from the Airbag Control Module (ACM) requesting
“Airbag” indicator illumination. This warning will only occur following completion of the “Airbag” indicator bulb
test, and will only occur once during any ignition cycle.
-- Compass Mini-Trip Computer Global Reset - The EMIC transducer will generate one short chime when the
ignition switch is in the On position, and an electronic message is received over the PCI data bus from the
optional Compass Mini-Trip Computer (CMTC) requesting that the CMTC average fuel economy, trip odometer
and distance to empty data be reset. The CMTC monitors hard wired inputs from the U.S./Metric and Reset
button switches to determine the proper reset messages to send to the EMIC.
-- Door Ajar Indicator Warning - The EMIC transducer will generate one short chime when the ignition switch
is in the On position, a hard wired input is received indicating that the status of any door ajar switch has
changed, and an electronic message is received over the PCI data bus indicating that the vehicle is moving.
-- Engine Coolant Temperature High Warning (Diesel Engine Only) - The EMIC transducer will generate a
single chime tone when the “Check Gauges” indicator is illuminated for a high or critical engine coolant temperature
condition. The instrument cluster uses engine coolant temperature message inputs received from the
diesel Engine Control Module (ECM) over the PCI data bus to illuminate the “Check Gauges” indicator for a
coolant temperature high condition.
-- Fasten Seat Belt Indicator Warning - The EMIC transducer will generate repetitive chimes at a slow rate to
announce that a hard wired input from the seat belt 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. (Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER/
SEATBELT INDICATOR - OPERATION).
--Head/Park Lamps-On Warning - The EMIC 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 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, or the battery saver (load shed) time-out expires,
whichever occurs first.
--Key-In-Ignition Warning - The EMIC transducer will generate repetitive chimes at a fast rate to announce that
the hard wired 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 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.
--Low Fuel Indicator Warning - The EMIC transducer will generate one short chime tone when the “Low Fuel”
indicator is illuminated by the instrument cluster circuitry. This chime will only occur once during any ignition
cycle.
-- Low Oil Pressure Warning (Diesel Engine Only) - The EMIC transducer will generate repetitive chimes at a
fast rate when the “Check Gauges” indicator is illuminated for a low oil pressure condition. The instrument
cluster uses engine speed and oil pressure message inputs received from the diesel Engine Control Module
(ECM) over the PCI data bus indicating that the engine is running and that the oil pressure is low to illuminate
the “Check Gauges” indicator. The chimes will continue to sound for five seconds, until the engine oil pressure
message indicates that the oil pressure is not low, or until the engine speed message indicates that the engine
is not running, whichever occurs first. This chime will only occur once during any ignition cycle.
--Low Wash Indicator Warning - The EMIC transducer will generate one short chime when the “Low Washer
Fluid” indicator is illuminated by the instrument cluster circuitry. This chime will only occur once during any
ignition cycle.
--Overspeed Warning - The EMIC transducer will generate repetitive chimes at a slow rate to indicate that the
vehicle speed is over a pre-programmed speed value. The EMIC monitors electronic vehicle speed messages
received over the PCI data bus. This feature is only enabled on an EMIC that has been programmed with a
Middle East Gulf Coast Country (GCC) country code.
--Park Brake Reminder - The EMIC transducer will generate ten repetitive chimes at a slow rate to announce
that the hard wired input from the park brake switch and a vehicle speed message input received over the PCI
data bus indicate that the park brake is applied and the vehicle is moving. This chime will repeat each time the
input conditions are met.
--Sentry Key “Customer Learn” Mode Announcement - The EMIC transducer will generate one short chime
to confirm that an electronic “Customer Learn” mode message has been received over the PCI data bus to
indicate the Sentry Key Immobilizer Module (SKIM) is prepared for programming additional sentry key transponders.
This chime feature is only active on vehicles equipped with the optional Sentry Key Immobilizer
System (SKIS), and sold in markets where “Customer Learn” programming is an allowed feature.
--Trans Overtemp Indicator Warning (Automatic Transmission Only) - The EMIC transducer will generate
repetitive chimes at a slow rate when the “Trans Temp” indicator is illuminated by the instrument cluster circuitry
for a high or critical transmission fluid temperature condition. This chime will repeat each time the trans
overtemp indicator is cycled from Off to On.
--Turn Signal/Hazard Warning Flasher Emulation - The EMIC 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 relay will generate repetitive clicks at a fast rate to indicate that the right or left turn signal are
operating with one or more bulbs inoperative. In either case, the clicks will continue until the turn signal and
hazard warning systems are turned off.
--Turn Signal On Warning - The EMIC transducer will generate repetitive chimes at a slow rate 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 for this feature. The chime will continue until the turn signal
input becomes inactive or until the vehicle speed message indicates that the speed is less than 22 kilometersper-
hour (15 miles-per-hour), whichever occurs first. The hazard warning flashers will not activate this chime
feature.
--Warning Indicator Announcement - The EMIC transducer will generate one short chime each time the
“Check Gauges” indicator is illuminated by the instrument cluster circuitry. The “Check Gauges” indicator may
be illuminated when any critical engine or transmission systems are operating outside of their normal parameters.
The instrument cluster monitors electronic messages received over the PCI data bus to determine when
to illuminate the “Check Gauges” indicator.
