Instrument Cluster - Service Information - Nitro
INSTRUMENT CLUSTER
DESCRIPTION




The EMIC gauges and indicators are visible through three dedicated openings in the cluster bezel and are
protected by a clear plastic cluster lens (5). Nine integral latch formations on the lens secure it to the cluster
hood and mask unit (4) as well as the cluster housing (2). Just behind the cluster lens is the cluster hood and
integral mask, which is constructed of molded black plastic. The hood serves as a visor and shields the face of
the cluster from ambient light and reflections to reduce glare, while the cluster mask serves to separate and
define the individual gauges and trims the outside perimeter of the cluster overlay. The hood and mask unit has
eight integral latch features that secure it to the outer perimeter of the cluster housing. The hood and mask unit
also has two integral mounting tabs on the lower corners that combine with the tabs integral to the cluster
housing to secure the bottom of the EMIC to the molded plastic instrument panel cluster carrier with two
screws.
The rear of the cluster housing and the EMIC electronic circuitry are protected by a molded white plastic rear
cover (1), which is also secured to the cluster housing by integral latch features. The rear cover includes
clearance holes for the four cluster connector receptacles. The connector receptacles on the back of the cluster
electronic circuit board connect the EMIC to the vehicle electrical system through four take outs with
connectors from the instrument panel wire harness.
Sandwiched between the rear cover and the lens and hood unit is the cluster housing. The molded white plastic
cluster housing serves as the carrier for the cluster circuit board and circuitry, the cluster connector receptacles,
the two major and two minor gauges, a Light Emitting Diode (LED) for each cluster indicator, the VFD display
units, an audible tone transducer, several LED units for general cluster illumination, the cluster overlay, and the
gauge pointers. The standard equipment molded black plastic odometer/trip odometer switch button (3) extends
from the face of the cluster housing through dedicated holes in the cluster mask and the cluster lens adjacent to
their respective VFD units. A black rubber grommet seals the switch button to the clearance hole in the lens.
The cluster housing also has four integral mounting tabs, one on each upper and lower corner of the housing.

The cluster overlay is a laminated plastic unit. The dark, visible, outer surface of the overlay is marked with all
of the gauge dial faces and graduations, but this layer is also translucent. The darkness of this outer layer
prevents the cluster from appearing cluttered or busy by concealing the cluster indicators that are not
illuminated, while the translucence of this layer allows those indicators and icons that are illuminated to be readily visible. The underlying layer of the overlay is opaque and allows light from the LED for each of the
various indicators and illumination lamps behind it to be visible through the outer layer of the overlay through
predetermined stencil-like cutouts. Openings in the overlay at the base of the tachometer and the minor gauge
set dial faces have smoked clear lenses through which the illuminated VFD units can be viewed.
Several versions of the EMIC module are offered on this vehicle. These versions accommodate all of the
variations of optional equipment and regulatory requirements for the various markets in which the vehicle is
offered. The microprocessor-based EMIC utilizes integrated circuitry and information carried on the Controller
Area Network (CAN) data bus and the Local Interface Network (LIN) data bus along with several hard wired
analog and multiplexed inputs to monitor sensors and switches throughout the vehicle. In response to those
inputs, the internal circuitry and programming of the EMIC allow it to control and integrate many electronic
functions and features of the vehicle through both hard wired outputs and the transmission of electronic
message outputs to other electronic modules in the vehicle over the CAN and LIN data busses.

Besides typical instrument cluster gauge and indicator support, the electronic functions and features that the
EMIC supports or controls include the following:
 Audible Warnings - The EMIC electronic circuit board is equipped with an audible tone transducer and
programming that allows it to provide various audible alerts to the vehicle operator. These alerts include
single chime tones and continuous slow or fast tones. An electromechanical relay is also soldered onto the
circuit board to produce audible clicks that are used to emulate the sound of a conventional turn signal or
hazard warning flasher.
 Compass/Temperature Display Support - The EMIC provides support for each of the functions and
features of the compass/temperature display, as well as for the odometer push button switch, which also
provides user inputs to control the compass/temperature display options.
 Electronic Vehicle Information Center Display Support - The EMIC provides support for each of the
functions and features of the Electronic Vehicle Information Center (EVIC) display. This includes
support for the compass, thermometer and audio system mode, customer programmable features, textual
warnings, premium Tire Pressure Monitor (TPM), trip computer, U-Connect™ Hands-Free
communication and the switch inputs from the two EVIC rocker switches located on the front surface of
the steering wheel spokes that are used to control and configure many of the displays. This also includes
display arbitrator programming, which controls the priorities, sequences, and transition of information
that is displayed in the EVIC display, particularly when multiple display requests are received
simultaneously.
 Enhanced Accident Response Support - The EMIC monitors inputs from the Occupant Restraint
Controller (ORC) and the Powertrain Control Module (PCM) to automatically turn ON the interior
lighting after an airbag deployment event, 10 seconds after the vehicle speed is zero. The interior lighting
remains illuminated until the key is removed from the ignition switch lock cylinder, at which time the
interior lighting returns to normal operation and control. These Enhanced Accident Response System
(EARS) features are each dependent upon a functional vehicle electrical system following the vehicle
impact event.
 Exterior Lighting Switch Support - The EMIC monitors electronic exterior lighting switch , and turn
signal switch status messages from the Steering Control Module (SCM) on the steering column over the
LIN data bus and transmits the appropriate electronic exterior lighting and turn signal request messages
to the Totally Integrated Power Module (TIPM) over the CAN data bus to support the exterior lighting functions.
 Horn Switch Support - On vehicles without the optional EVIC, the EMIC receives a hard wired input
from the horn switch on the steering wheel. On vehicles with the optional EVIC, the EMIC receives
electronic horn switch status messages from the Steering Wheel Switch Module (SWSM) over the LIN
bus. In either case, the EMIC then provides electronic horn request messages over the CAN data bus to
support the horn function.
 Interior Lamp Load Shedding - The EMIC provides a battery saver feature which will automatically
turn OFF all interior lamps if they remain ON after a timed interval of about ten minutes.
 Interior Lighting Control - The EMIC monitors electronic messages and hard wired inputs from the
reading lamp switches, the Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless
Control Module/WCM), the Steering Control Module (SCM) and the Totally Integrated Power Module
(TIPM) to provide courtesy lamp control. This includes support for timed illuminated entry with theaterstyle
fade-to-OFF and courtesy illumination DEFEAT features.
 Local Interface Network Master Module - The EMIC is the master module for the LIN data bus. In this
role it gathers information from the compass sensor, the Heated Seat Module (HSM), the instrument
panel switch pod, the Steering Wheel Switch Module (SWSM), the SCM and the remote compass
module, then either acts on that information directly or places electronic messages on the CAN data bus
for use by other modules
 Panel Lamps Dimming Control - The EMIC monitors electronic dimming level messages received
from the panel lamps dimmer switch input to the SCM over the LIN data bus, then provides both a hard
wired 12-volt Pulse-Width Modulated (PWM) output and electronic message outputs over the CAN data
bus and the LIN data bus that synchronizes the dimming level of all panel lamps dimmer controlled lamps
with that of the cluster general illumination lighting.
 Wiper and Washer Switch Support - The EMIC monitors electronic wiper switch and washer switch
status messages from the SCM on the steering column over the LIN data bus and transmits the
appropriate electronic wiper and washer request messages to the TIPM over the CAN data bus to
support the wiper and washer system functions, including the headlamps-on with wipers programmable
feature.

The EMIC houses four analog gauges and has provisions for up to 25 indicators. Some of the EMIC indicators are automatically configured when the EMIC is connected to the vehicle electrical system for compatibility with
certain optional equipment or equipment required for regulatory purposes in certain markets. While each EMIC
may have provisions for indicators to support every available option, the configurable indicators will not be
functional in a vehicle that does not have the equipment that an indicator supports.
The EMIC includes the following analog gauges:
 Engine Temperature Gauge (5)
 Fuel Gauge (1)
 Speedometer (6)
 Tachometer (11)
The EMIC includes the following VFD display units:
 Odometer Display (15) - includes Cruise indicator (13), Gear Selector indicator (12), Malfunction
Indicator Lamp (MIL) (16) and Tire Pressure Monitor (TPM) indicator (14).
 Compass-Temperature or Electronic Vehicle Information Center Display (31)
The EMIC includes provisions for the following indicators:
 Airbag Indicator (30)
 Ajar Indicators (15 or 31) - text in odometer display for doors and liftgate in clusters without EVIC, or
icons in the EVIC display of vehicles with that option
 Antilock Brake System (ABS) Indicator (27)
 Brake Indicator (19) - text only for U.S. market, icon only for markets outside U.S.
 Charging Indicator (23)
 Cruise Indicator (13)
 Electronic Stability Program (ESP)/Brake Assist System (BAS) Indicator (9)
 Electronic Throttle Control (ETC) Indicator (20)
 Engine Coolant Temperature Indicator (4)
 Front Fog Lamp Indicator (28) - with optional front fog lamps only
 Gas Cap Indicator - textual message in odometer display (15)
 Gear Selector Indicator (12) - with automatic transmission only
 High Beam Indicator (7)
 Low Fuel Indicator (2)
 Low Oil Pressure Indicator (29)
 Malfunction Indicator Lamp (MIL) (16)
 Rear Fog Lamp Indicator (21) - in markets where rear fog lamps are available only
 Seat Belt Indicator (3)
 Security Indicator (8)
 Service Four-Wheel Drive (4WD) Indicator (26) - with optional four-wheel drive system only The microprocessor-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 messages that are transmitted by other electronic modules over the Controller Area Network (CAN)
data bus or the Local Interface Network (LIN) data bus. The EMIC is the master node for the LIN data bus.
Refer to OPERATION .
The EMIC microprocessor smooths the input data using algorithms to provide gauge readings that are accurate,
stable and responsive to operating conditions. These algorithms are designed to provide gauge readings during
normal operation that are consistent with customer expectations. However, when abnormal conditions exist
such as high coolant temperature, the algorithm can drive the gauge pointer to an extreme position and the
microprocessor can sound a chime through the on-board audible tone transducer to provide distinct visual and
audible indications of a problem to the vehicle operator. The EMIC may also produce audible warnings for
other electronic modules in the vehicle based upon electronic tone request messages received over the CAN or
LIN data bus. Each audible warning is intended to provide the vehicle operator with an audible alert to
supplement a visual indication.
The EMIC circuitry operates on battery current received through a fused B(+) fuse on a non-switched fused B
(+) circuit, and on battery current received through a fused ignition switch output (run-start) fuse on a fused
ignition switch output (run-start) circuit. This arrangement allows the EMIC to provide some features regardless
of the ignition switch position, while other features will operate only with the ignition switch in the ON or
START positions. The EMIC circuitry is grounded through a ground circuit and take out of the instrument panel
wire harness with an eyelet terminal connector that is secured by a ground screw to a ground location on the
instrument panel structural support.
The EMIC also has a self-diagnostic actuator test capability, which will test each of the CAN or LIN bus
message-controlled functions of the cluster by lighting the appropriate indicators, positioning the gauge needles
at several predetermined calibration points across the gauge faces, and illuminating all segments of the
Vacuum-Fluorescent Display (VFD) units. See DIAGNOSIS AND TESTING.
GAUGES
All gauges receive battery current through the EMIC circuitry only when the ignition switch is in the ON or
START positions. With the ignition switch in the OFF position battery current is not supplied to any gauges,
and the EMIC circuitry is programmed to move all of the gauge needles back to the low end of their respective
scales. Therefore, the gauges do not accurately indicate any vehicle condition unless the ignition switch is in the
ON or START positions.
Each of the EMIC gauges contains an electronically controlled stepper motor unit. The EMIC circuitry
completely controls the activation and deactivation of these stepper motors to position each gauge needle in the
appropriate position based upon cluster programming and electronic messages received over the CAN or LIN
data bus.
The gauges are diagnosed using the self-diagnostic Cab Compartment Node (CCN) actuator test. Proper testing
of the CAN or LIN data bus and the electronic data bus message inputs to the EMIC that control each gauge
requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information. Specific operation
details for each gauge may be found elsewhere in this service information.
VACUUM-FLUORESCENT DISPLAYS

compass/temperature display, the EVIC and the various warning and reminder indicator functions of the VFD
units may be found elsewhere in this service information.
INDICATORS
Indicators are located in various positions within the EMIC and are all connected to the EMIC electronic circuit
board. Some indicators operate based upon hard wired inputs to the EMIC, but most are controlled by CAN or
LIN data bus messages from other electronic modules in the vehicle. Some are controlled by a combination of
hard wired inputs, electronic messaging and EMIC programming. If the EMIC loses CAN data bus
communication, the EMIC circuitry will automatically turn ON the Malfunction Indicator Lamp (MIL) until
CAN data bus communication is restored.
The various EMIC indicators are controlled by different strategies; some receive fused ignition switch output
from the EMIC circuitry and have a switched ground, while others are grounded through the EMIC circuitry
and have a switched battery feed. However, all indicators are completely controlled by the EMIC
microprocessor based upon various hard wired and electronic message inputs. The cruise and 4WD indicators
located within the odometer VFD unit are dimmable. All other indicators are illuminated at a fixed intensity,
which is not affected by the selected illumination intensity of the EMIC general illumination LED units. The
illumination intensity of the dimmable indicators is synchronized with that of the general illumination lighting.
In addition, certain indicators in this instrument cluster are automatically or self-configured. This feature allows
the configurable indicators to be enabled by the EMIC circuitry for compatibility with certain optional
equipment. These indicators are enabled or disabled by an electronic configuration message sent to the EMIC
by the Totally Integrated Power Module (TIPM). The TIPM defaults for the ABS indicator and airbag indicator
are enabled, and these configuration settings must be programmatically disabled in the TIPM using a diagnostic
scan tool for vehicles that do not have this equipment. The automatically or self-configured indicators remain
latent in each EMIC at all times and will be active only when the EMIC receives the appropriate CAN or LIN
bus message inputs for that optional system or equipment.
The hard wired indicator inputs may be diagnosed using conventional diagnostic tools and procedures.
However, the EMIC circuitry and electronic CAN or LIN data bus message controlled indicators are diagnosed
using the self-diagnostic Cab Compartment Node (CCN) actuator test. See DIAGNOSIS AND TESTING.
Proper testing of the CAN or LIN data bus and the electronic data bus message inputs to the EMIC that control
each indicator requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
Specific details of the operation for each indicator may be found elsewhere in this service information.

CLUSTER ILLUMINATION

The EMIC has several Light Emitting Diode (LED) units that provide cluster back lighting whenever the
exterior lighting is turned ON. The illumination intensity of these LED units is adjusted when the panel lamps
dimmer function of the control sleeve on the control stalk of the left (lighting) multi-function switch is rotated
to one of six available minor detent positions. The EMIC monitors an electronic dimming level message input
received over the LIN data bus from the Steering Control Module (SCM) to determine the selected lighting
level. In response to that input, the EMIC electronic circuitry converts a fused 12-volt input it receives on a hard
wired panel lamps dimmer switch signal circuit into a 12-volt Pulse Width Modulated (PWM) output.

The EMIC uses this PWM output to control the illumination intensity of the cluster general illumination lighting
and the VFD units on the EMIC circuit board, then provides a synchronized PWM output on various hard wired fused panel lamps dimmer switch signal circuits to control and synchronize the illumination intensity of other incandescent illumination lamps in the vehicle. The EMIC also transmits electronic dimming level messages over the CAN and LIN data bus to other electronic modules in the vehicle to control and synchronize the
illumination intensity of their display units to that of the EMIC displays.

The hard wired panel lamps dimmer outputs from the EMIC may be diagnosed using conventional diagnostic
tools and procedures. However, proper testing of the PWM processing of the EMIC and the electronic dimming
level messages received by the EMIC over the LIN data bus requires the use of a diagnostic scan tool.
