the status of t he dr iver side fron t seat belt . This
audible warnin g occur s in dependent of the visual
warn ing provided by t he EMIC “Seat belt” i n dicator.
• Li g h ts -On Wa rn in g - The EMIC chime t one
generat or will gen erat e repetitive chime t ones at a
fast ra te wh en either front door is open ed wit h the
ign ition switch in a ny posit ion except On, and th e
exterior light s ar e t urned On. The E MIC u ses int er-
nal program ming and hard wired inpu ts from the left
(lighting) control sta lk of the mult i-fun ction switch,
the ign ition switch , and bot h front door jamb
switch es to deter mine the cu rren t status of these
switch es. This chime will con tinue to sound un til the
exterior light ing is turned Off, until the ignition
switch is turned to th e On position, or until both
front doors a re closed, which ever occurs first.
• Ke y-In -Ig n iti o n Wa rn in g - Th e EMIC chime
tone gener ator will gen erat e r epetit ive chim e t ones at
a fast rate when th e key is in the ignition lock cylin-
der, the ignition switch is in an y position except On,
and either front door is open ed. The EMIC uses
internal pr ogrammin g and h ard wired inputs from
the key-in ignition switch , th e ignition switch , an d
both fr ont door jam b switches to det ermine the cur-
rent stat us of th ese switches. Th e chime will con-
tinue to soun d until the key is rem oved from the
ign ition lock cylinder, until th e ignition swit ch is
turned to the On position, or unt il both fron t doors
are closed, whichever occur s first.
• Au dib le Tu rn Sig n a l/H a z a rd Wa rn in g S u p-
port - The EMIC conta ctless relay will genera te
repetitive clicks at a slow rat e during normal tu rn
signal/ha zar d war ning oper ation, or at a fast rate
when a tu rn signa l lamp bulb or circuit is inoper a-
tive, in con cert with th e operation of t he turn signal
indicator s in th e cluster. These clicks ar e designed to
emulate t he sound of th e openin g and closing of t he
contact points in a convent ional electromechanical
turn signal or hazard warn ing flasher. The EMIC
uses a h ard wired inpu t received from t he turn sig-
nal relay in the fuse block beneath the st eering col-
umn through th e tur n signa l or hazard wa rning
switch circuitry of th e m ult i-funct ion swit ch t o deter-
mine when to flash the turn signal indicators a nd
activat e the contactless relay on the clust er electron ic
circuit board. The turn sign al clicks will continue to
sou nd until the tu rn signal switch is tur ned Off, or
until the ignition switch is t urned t o t he Off position,
which ever occur s fir st . The hazard war ning clicks
will continue to sou nd until t he haza rd warnin g
switch is tur ned Off.
The EMIC provides chim e ser vice for all available
featu res in the chim e warn ing system. The EMIC relies
upon its in tern al program ming and ha rd wired inputs
from the fr ont door ajar switches, t he key-in ignition
switch , th e ign ition switch , the seat belt swit ch, a nd the
turn sign al/hazar d wa rning (m ult i-funct ion) switches.
The EMIC relies u pon electronic message inputs
received from other electronic modules over the CAN
da ta bus n etwork to provide chime service for the low
engine oil level warn ing. Upon receiving the pr oper
input s, the EMIC activates th e chime t one gener ator or
the contact less relay to pr ovide the audible warning to
the vehicle operator. The in tern al progra mmin g of the
EMIC deter mines the priorit y of each chime request
input t hat is received, as well as t he ra te an d duration
of each ton e tha t is to be gen erat ed. See th e owner ’s
manual in the vehicle glove box for m ore informat ion on
the featu res provided by the chim e warning system.
The ha rd wired chime warn ing system inputs t o
the EMIC, as well as other ha rd wired circuits for
this system m ay be diagnosed and tested u sing con-
vent iona l diagnostic tools and procedures. However,
conven tional dia gnostic meth ods may n ot prove con-
clusive in the diagnosis of th e EMIC, the CAN data
bus networ k, or th e elect ronic message in puts used
by the EMIC to pr ovide chim e wa rning system ser-
vice. Th e most relia ble, efficient , and accurat e mea ns
to diagn ose the EMIC, the CAN data bus n etwork,
and the electron ic messa ge inpu ts for t he chime
warn ing system requir es the use of a dia gnostic scan
tool. Refer to the appropriate diagnostic infor mation.
DIAGNOSIS AND TESTING - CHIME WARNING
SYSTEM
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for
the system capacitor to discharge before perform-
ing further diagnosis or service. This is the only
sure way to disable the supplemental restraint sys-
tem. Failure to take the proper precautions could
result in accidental airbag deployment.
The ha rd wired chime warn ing system inputs t o
the ElectroMechanical Instrument Cluster (EMIC),
as well as other h ard wir ed circuits for this system
may be diagnosed and tested using conventional
diagnostic tools an d procedures. However, con ven-
tional diagnostic methods m ay not pr ove con clusive
in t he diagnosis of the EMIC, the Contr oller Area
Net work (CAN) data bus net work, or th e elect ronic
message inputs used by the EMIC to provide chime
warn ing system service. Th e most r elia ble, efficient,
and accur ate mea ns t o diagn ose th e EMIC, th e CAN
da ta bus n etwork, and the electronic message inputs
for the chime wa rning system requir es t he use of a
diagnostic scan tool. Refer to the appropriate diag-
nostic infor mation.
