OPERATION
The ElectroMechanical Instrument Cluster (EMIC)
is designed to allow the vehicle operator to monitor
the conditions of many of the vehicle components and
operating systems. The gauges and indicators in the
EMIC provide valuable information about the various
standard and optional powertrains, fuel and emis-
sions systems, cooling systems, lighting systems,
safety systems and many other convenience items.
The EMIC is installed in the instrument panel so
that all of these monitors can be easily viewed by the
vehicle operator when driving, while still allowing
relative ease of access for service. The microproces-
sor-based EMIC hardware and software uses various
inputs to control the gauges and indicators visible on
the face of the cluster. Some of these inputs are hard
wired, but most are in the form of electronic mes-
sages that are transmitted by other electronic mod-ules over the Programmable Communications
Interface (PCI) data bus network. (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/COMMUNICATION - OPERATION).
The EMIC microprocessor smooths the input data
using algorithms to provide gauge readings that are
accurate, stable and responsive to operating condi-
tions. These algorithms are designed to provide
gauge readings during normal operation that are con-
sistent with customer expectations. However, when
abnormal conditions exist, such as low or high bat-
tery voltage, low oil pressure or high coolant temper-
ature, the algorithm can drive the gauge pointer to
an extreme position and the microprocessor turns on
the Check Gauges indicator to provide a distinct
visual indication of a problem to the vehicle operator.
The instrument cluster circuitry also sends electronic
chime tone request messages over the PCI data bus
to the Body Control Module (BCM) when it monitors

the gauge needle at the last indication for about
twelve seconds or until a new engine temperature
message is received, whichever occurs first. After
twelve seconds, the cluster will return the gauge nee-
dle to the low end of the gauge scale.
²Actuator Test- Each time the cluster is put
through the actuator test, the gauge needle will be
swept across the entire gauge scale and back in order
to confirm the functionality of the gauge and the
cluster control circuitry.
The PCM continually monitors the engine coolant
temperature sensor to determine the engine operat-
ing temperature. The PCM then sends the proper
engine coolant temperature messages to the instru-
ment cluster. For further diagnosis of the engine cool-
ant temperature gauge or the instrument cluster
circuitry that controls the gauge, (Refer to 8 - ELEC-
TRICAL/INSTRUMENT CLUSTER - DIAGNOSIS
AND TESTING). If the instrument cluster moves the
engine coolant temperature gauge needle to indicate
a high or critical engine temperature, it may indicate
that the engine or the engine cooling system requires
service. For proper diagnosis of the engine coolant
temperature sensor, the PCM, the PCI data bus, or
the electronic message inputs to the instrument clus-
ter that control the engine coolant temperature
gauge, a DRBIIItscan tool is required. Refer to the
appropriate diagnostic information.
FRONT FOG LAMP INDICATOR
DESCRIPTION
A front fog lamp indicator is standard equipment
on all instrument clusters, but is only functional on
vehicles equipped with the optional front fog lamps.
The front fog lamp indicator is located on the left
edge of the instrument cluster, to the left of the
tachometer. The front fog lamp indicator consists of
an International Control and Display Symbol icon for
ªFront Fog Lightº imprinted on a green lens. The
lens is located behind a cutout in the opaque layer of
the instrument cluster overlay. The dark outer layer
of the overlay prevents the indicator from being
clearly visible when it is not illuminated. The icon
appears silhouetted against a green field through the
translucent outer layer of the overlay when the indi-
cator is illuminated from behind by a replaceable
incandescent bulb and bulb holder unit located on
the instrument cluster electronic circuit board. When
the exterior lighting is turned On, the illumination
intensity of the front fog lamp indicator is dimmable,
which is adjusted using the panel lamps dimmer con-
trol ring on the control stalk of the left multi-func-
tion switch. The front fog lamp indicator lens isserviced as a unit with the instrument cluster lens,
hood and mask unit.
OPERATION
The front fog lamp indicator gives an indication to
the vehicle operator whenever the front fog lamps
are illuminated. This indicator is controlled by a
transistor on the instrument cluster circuit board
based upon cluster programming and electronic mes-
sages received by the cluster from the Body Control
Module (BCM) over the Programmable Communica-
tions Interface (PCI) data bus. The front fog lamp
indicator bulb is completely controlled by the instru-
ment cluster logic circuit, and that logic will allow
this indicator to operate whenever the instrument
cluster receives a battery current input on the fused
B(+) circuit. Therefore, the indicator can be illumi-
nated regardless of the ignition switch position. The
bulb only illuminates when it is provided a path to
ground by the instrument cluster transistor. The
instrument cluster will turn on the front fog lamp
indicator for the following reasons:
²Front Fog Lamp Indicator Lamp-On Mes-
sage- Each time the cluster receives a front fog
lamp indicator lamp-on message from the BCM indi-
cating that the front fog lamps are turned On, the
front fog lamp indicator will be illuminated. The indi-
cator remains illuminated until the cluster receives a
front fog lamp indicator lamp-off message from the
BCM.
²Actuator Test- Each time the cluster is put
through the actuator test, the front fog lamp indica-
tor will be turned on for the duration of the test to
confirm the functionality of the bulb and the cluster
control circuitry.
The BCM continually monitors the exterior light-
ing (left multi-function) switch to determine the
proper outputs to the front fog lamp relay. The BCM
then sends the proper front fog lamp indicator
lamp-on and lamp-off messages to the instrument
cluster. If the front fog lamp indicator fails to light
during the actuator test, replace the bulb with a
known good unit. For further diagnosis of the front
fog lamp indicator or the instrument cluster circuitry
that controls the indicator, (Refer to 8 - ELECTRI-
CAL/INSTRUMENT CLUSTER - DIAGNOSIS AND
TESTING). For proper diagnosis of the front fog
lamp system, the BCM, the PCI data bus, or the elec-
tronic message inputs to the instrument cluster that
control the front fog lamp indicator, a DRBIIItscan
tool is required. Refer to the appropriate diagnostic
information.

pletely controlled by the instrument cluster logic cir-
cuit, and that logic will only allow this indicator to
operate when the instrument cluster receives a bat-
tery current input on the fused ignition switch out-
put (run-start) circuit. Therefore, the indicator will
always be off when the ignition switch is in any posi-
tion except On or Start. The bulb only illuminates
when it is provided a path to ground by the instru-
ment cluster transistor. The instrument cluster will
turn on the overdrive off indicator for the following
reasons:
²Bulb Test- Each time the ignition switch is
turned to the On position the overdrive off indicator
is illuminated for about three seconds as a bulb test.
²Overdrive Off Indicator Lamp-On Message-
Each time the cluster receives an overdrive off indi-
cator lamp-on message from the PCM or TCM indi-
cating that the Off position of the overdrive off
switch has been selected, the overdrive off indicator
will be illuminated. The indicator remains illumi-
nated until the cluster receives an overdrive off indi-
cator lamp-off message from the PCM or TCM, or
until the ignition switch is turned to the Off position,
whichever occurs first.
²Actuator Test- Each time the cluster is put
through the actuator test, the overdrive off indicator
will be turned on for the duration of the test to con-
firm the functionality of the bulb and the cluster con-
trol circuitry.
The PCM or TCM continually monitors the over-
drive off switch to determine the proper outputs to
the automatic transmission. The PCM or TCM then
sends the proper overdrive off indicator lamp-on or
lamp-off messages to the instrument cluster. If the
overdrive off indicator fails to light during the bulb
test, replace the bulb with a known good unit. For
further diagnosis of the overdrive off indicator or the
instrument cluster circuitry that controls the indica-
tor, (Refer to 8 - ELECTRICAL/INSTRUMENT
CLUSTER - DIAGNOSIS AND TESTING). For
proper diagnosis of the overdrive control system, the
PCM, the TCM, the PCI data bus, or the electronic
message inputs to the instrument cluster that control
the overdrive off indicator, a DRBIIItscan tool is
required. Refer to the appropriate diagnostic infor-
mation.
REAR FOG LAMP INDICATOR
DESCRIPTION
A rear fog lamp indicator is standard equipment on
all instrument clusters, but is only functional on
vehicles equipped with optional rear fog lamps,
which are available only in certain international
markets where they are required. The rear fog lampindicator is located on the left edge of the instrument
cluster, to the left of the tachometer. The rear fog
lamp indicator consists of an International Control
and Display Symbol icon for ªRear Fog Lightº
imprinted on an amber lens. The lens is located
behind a cutout in the opaque layer of the instru-
ment cluster overlay. The dark outer layer of the
overlay prevents the indicator from being clearly vis-
ible when it is not illuminated. The icon appears sil-
houetted against an amber field through the
translucent outer layer of the overlay when the indi-
cator is illuminated from behind by a replaceable
incandescent bulb and bulb holder unit located on
the instrument cluster electronic circuit board. When
the exterior lighting is turned On, the illumination
intensity of the rear fog lamp indicator is dimmable,
which is adjusted using the panel lamps dimmer con-
trol ring on the control stalk of the left multi-func-
tion switch. The rear fog lamp indicator lens is
serviced as a unit with the instrument cluster lens,
hood and mask unit.
OPERATION
The rear fog lamp indicator gives an indication to
the vehicle operator whenever the rear fog lamps are
illuminated. This indicator is controlled by a transis-
tor on the instrument cluster electronic circuit board
based upon cluster programming and electronic mes-
sages received by the cluster from the Body Control
Module (BCM) over the Programmable Communica-
tions Interface (PCI) data bus. The rear fog lamp
indicator bulb is completely controlled by the instru-
ment cluster logic circuit, and that logic will allow
this indicator to operate whenever the instrument
cluster receives a battery current input on the fused
B(+) circuit. Therefore, the indicator can be illumi-
nated regardless of the ignition switch position. The
bulb only illuminates when it is provided a path to
ground by the instrument cluster transistor. The
instrument cluster will turn on the rear fog lamp
indicator for the following reasons:
²Rear Fog Lamp Indicator Lamp-On Mes-
sage- Each time the cluster receives a rear fog lamp
indicator lamp-on message from the BCM indicating
that the rear fog lamps are turned On, the rear fog
lamp indicator will be illuminated. The indicator
remains illuminated until the cluster receives a rear
fog lamp indicator lamp-off message from the BCM.
²Actuator Test- Each time the cluster is put
through the actuator test, the rear fog lamp indicator
will be turned on for the duration of the test to con-
firm the functionality of the bulb and the cluster con-
trol circuitry.
The BCM continually monitors the exterior light-
ing (left multi-function) switch to determine the
proper outputs to the rear fog lamp relay. The BCM

then sends the proper rear fog lamp indicator
lamp-on and lamp-off messages to the instrument
cluster. If the rear fog lamp indicator fails to light
during the actuator test, replace the bulb with a
known good unit. For further diagnosis of the rear
fog lamp indicator or the instrument cluster circuitry
that controls the indicator, (Refer to 8 - ELECTRI-
CAL/INSTRUMENT CLUSTER - DIAGNOSIS AND

the rear fog lamp indicator, a DRBIIItscan tool is
required. Refer to the appropriate diagnostic infor-
mation.
SEATBELT INDICATOR
DESCRIPTION
A seatbelt indicator is standard equipment on all
instrument clusters. The seatbelt indicator is located
near the lower edge of the instrument cluster, to the
left of the tachometer. The seatbelt indicator consists
of an International Control and Display Symbol icon
for ªSeat Beltº imprinted on a red lens. The lens is
located behind a cutout in the opaque layer of the
instrument cluster overlay. The dark outer layer of
the overlay prevents the icon from being clearly vis-
ible when the indicator is not illuminated. The icon
appears silhouetted against a red field through the
translucent outer layer of the overlay when it is illu-
minated from behind by a Light Emitting Diode
(LED), which is soldered onto the instrument cluster
electronic circuit board. The seatbelt indicator lens is
serviced as a unit with the instrument cluster lens,
hood and mask unit.
OPERATION
The seatbelt indicator gives an indication to the
vehicle operator of the status of the driver side front
seatbelt. This indicator is controlled by a transistor
on the instrument cluster electronic circuit board
based upon cluster programming. On models
equipped with airbags the indicator is also controlled
by electronic messages received by the cluster from
the Airbag Control Module (ACM) over the Program-
mable Communications Interface (PCI) data bus. The
seatbelt indicator Light Emitting Diode (LED) is
completely controlled by the instrument cluster logic
circuit, and that logic will only allow this indicator to
operate when the instrument cluster receives a bat-
tery current input on the fused ignition switch out-
put (run-start) circuit. Therefore, the indicator willalways be off when the ignition switch is in any posi-
tion except On or Start. The LED only illuminates
when it is provided a path to ground by the instru-
ment cluster transistor. The instrument cluster will
turn on the seatbelt indicator for the following rea-
sons:
²Seatbelt Reminder Function- Each time the
cluster receives a battery current input on the fused
ignition switch output (run-start) circuit, the indica-
tor will be illuminated as a seatbelt reminder for
about six seconds, or until the ignition switch is
turned to the Off position, whichever occurs first.
This reminder function will occur regardless of the
status of the electronic seat belt lamp-on or lamp-off
messages received by the cluster from the ACM.
²Seat Belt Indicator Lamp-On Message-On
models equipped with airbags, following the seatbelt
reminder function, each time the cluster receives a
seat belt indicator lamp-on message from the ACM
indicating the driver side front seat belt is not fas-
tened with the ignition switch in the Start or On
positions, the seatbelt indicator will be illuminated.
The indicator remains illuminated until the cluster
receives a seat belt indicator lamp-off message from
the ACM, or until the ignition switch is turned to the
Off position, whichever occurs first.
²Actuator Test- Each time the cluster is put
through the actuator test, the seatbelt indicator will
be turned on for the duration of the test to confirm
the functionality of the LED and the cluster control
circuitry.
The instrument cluster continually monitors the
status of the ignition switch through the hard wired
fused ignition switch output (run-start) circuit to
determine when to provide the seatbelt reminder
function. On models equipped with airbags, the ACM
continually monitors the status of both front seat belt
switches to determine the proper airbag system
response to a frontal impact of the vehicle. The ACM
then sends the proper seatbelt indicator lamp-on and
lamp-off messages to the instrument cluster based
upon the status of the driver side front seat belt
switch input. For further diagnosis of the seatbelt
indicator or the instrument cluster circuitry that con-
trols the indicator, (Refer to 8 - ELECTRICAL/IN-
STRUMENT CLUSTER - DIAGNOSIS AND
TESTING). For proper diagnosis of the seatbelt
switches, the ACM, the PCI data bus, or the elec-
tronic message inputs to the instrument cluster that
control the seatbelt indicator, a DRBIIItscan tool is
required. Refer to the appropriate diagnostic infor-
mation.
