0 - 8 LUBRICATION & MAINTENANCEVA

Located between the rear cover and the cluster
hood is the cluster housing. The molded plastic clus-
ter housing serves as the carrier for the cluster elec-
tronic circuit board and circuitry, the cluster
connector receptacles, the gauges, a Light Emitting
Diode (LED) for each cluster indicator and general
illumination lamp, the multi-function indicator LCD
unit, electronic tone generators, the cluster overlay,
the gauge pointers, the multi-function indicator
switches and the four switch push buttons.
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 clut-
tered 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 illu-
mination lamps behind it to be visible through the
outer layer of the overlay only through predeter-
mined cutouts. A rectangular opening in the overlay
at the base of the speedometer provides a window
through which the illuminated multi-function indica-
tor LCD unit can be viewed.
Several versions of the EMIC module are offered
on this model. These versions accommodate all of the
variations of optional equipment and regulatory
requirements for the various markets in which the
vehicle will be offered. The microprocessor-based
EMIC utilizes integrated circuitry, Electrically Eras-
able Programmable Read Only Memory (EEPROM)
type memory storage, information carried on the
Controller Area Network (CAN) data bus, along with
several hard wired analog and multiplexed inputs to
monitor systems, sensors and switches throughout
the vehicle.
In response to those inputs, the hardware and soft-
ware of the EMIC allow it to control and integrate
many electronic functions and features of the vehicle
through both hard wired outputs and the transmis-
sion of electronic message outputs to other electronic
modules in the vehicle over the CAN data bus. (Refer
to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/COMMUNICATION - DESCRIPTION -
CAN BUS).
Besides typical instrument cluster gauge and indi-
cator support, the electronic functions and features
that the EMIC supports or controls include the fol-
lowing:
²Active Service System- In vehicles equipped
with the Active Service SYSTem (ASSYST) engine oil
maintenance indicator option, the EMIC electronic
circuit board includes a second dedicated micropro-
cessor. This second microprocessor evaluates various
data including time, mileage, and driving conditionsto calculate the required engine oil service intervals,
and provides both visual and audible alerts to the
vehicle operator when certain engine oil maintenance
services are required.
²Audible Warnings- The EMIC electronic cir-
cuit board is equipped with an audible tone generator
and programming that allows it to provide various
audible alerts to the vehicle operator, including buzz-
ing and chime tones. An audible contactless elec-
tronic relay is also soldered onto the circuit board to
produce audible clicks that is synchronized with turn
signal indicator flashing to emulate the sounds of a
conventional turn signal or hazard warning flasher.
These audible clicks can occur at one of two rates to
emulate both normal and bulb-out turn or hazard
flasher operation. (Refer to 8 - ELECTRICAL/
CHIME/BUZZER - DESCRIPTION).
²Panel Lamps Dimming Control- The EMIC
provides a hard wired 12-volt Pulse-Width Modulated
(PWM) output that synchronizes the dimming level
of all panel lamps dimmer controlled lamps with that
of the cluster general illumination lamps and multi-
function indicator.
The EMIC houses four analog gauges and has pro-
visions for up to nineteen indicators (Fig. 3). The
EMIC includes the following analog gauges:
²Coolant Temperature Gauge
²Fuel Gauge
²Speedometer
²Tachometer
The EMIC includes provisions for the following
indicators (Fig. 3):
²Airbag (SRS) Indicator
²Antilock Brake System (ABS) Indicator
²Brake Indicator
²Brake Wear Indicator
²Charging Indicator
²Clogged Fuel Filter Indicator
²Constant Engine Speed (ADR) Indicator

VAINSTRUMENT CLUSTER 8J - 3

Except for the indications provided within the
multi-function indicator LCD unit, each indicator in
the EMIC is illuminated by a dedicated LED that is
soldered onto the EMIC electronic circuit board.
Cluster illumination is accomplished by dimmable
LED back lighting, which illuminates the gauges for
visibility when the exterior lighting is turned on. The
cluster general illumination LED units are also sol-
dered onto the EMIC electronic circuit board. The
LED units are not available for service replacement
and, if damaged or faulty, the entire EMIC must be
replaced.Hard wired circuitry connects the EMIC to the
electrical system of the vehicle. These hard wired cir-
cuits are integral to the vehicle wire harnesses,
which are routed throughout the vehicle and retained
by many different methods. These circuits may be
connected to each other, to the vehicle electrical sys-
tem and to the EMIC through the use of a combina-
tion of soldered splices, splice block connectors, and
many different types of wire harness terminal con-
nectors and insulators. Refer to the appropriate wir-
ing information. The wiring information includes
wiring diagrams, proper wire and connector repair

The airbag used in this model is a Next Genera-
tion-type that complies with revised federal airbag
standards to deploy with less force than those used
in some prior models. A radial deploying fabric cush-
ion with internal tethers is used. The airbag inflator
is a solid fuel, pyrotechnic-type unit with four studs
and is secured by four hex nuts to four studs on the
airbag cushion retainer ring to the back of the
stamped metal airbag housing. A keyed connector
receptacle on the driver airbag inflator connects the
inflator initiator to the vehicle electrical system
through a yellow-jacketed, two-wire pigtail harness of
the clockspring.
The driver airbag and trim cover unit cannot be
repaired, and must be replaced if deployed, faulty, or
in any way damaged.
OPERATION
The driver airbag is deployed by electrical signals
generated by the Airbag Control Module (ACM)
through the driver airbag squib circuit to the initia-
tor in the airbag inflator (Fig. 20). When the ACM
sends the proper electrical signal to the initiator the
electrical energy generates enough heat to initiate a
small pyrotechnic charge which, in turn, ignites
chemical pellets within the inflator. Once ignited,
these chemical pellets burn rapidly and produce a
large quantity of inert gas. The inflator is sealed to
the back of the airbag housing and a diffuser in the
inflator directs all of the inert gas into the airbag
cushion, causing the cushion to inflate. As the cush-
ion inflates, the driver airbag trim cover will split at
predetermined breakout lines, then fold back out of
the way. Following an airbag deployment, the airbag
cushion quickly deflates by venting the inert gas
towards the instrument panel through filtered vents
within the fabric used to construct the back (steering
wheel side) panel of the airbag cushion.
Some of the chemicals used to create the inert gas
may be considered hazardous while in their solid
state before they are burned, but they are securely

PASSENGER AIRBAG
DESCRIPTION
The rearward facing surface of the injection
molded, thermoplastic passenger airbag door is the
most visible part of the optional passenger airbag
(Fig. 27). The passenger airbag door is located above
the glove box opening in front of the front seat pas-
senger seating position on the instrument panel. The
upper and lower edges of the airbag door are secured
by a snap-fit to molded plastic clips. The two clips at
the top are each secured by a screw to the instru-
ment panel base trim, while the clips at the bottom
are integral to the panel that surrounds the passen-
ger airbag door opening in the instrument panel base
trim. The airbag door is also secured to the airbag
housing by two wide woven straps that serve as
hinges for the door upon an airbag deployment.
Located behind the passenger airbag door is the
passenger airbag unit (Fig. 28). The airbag housing
is constructed of a long U-shaped aluminum extru-
sion with two stamped steel end plates. A stepped
flange that extends from the back of the extrusion
serves as the airbag mounting flange. This mountingflange is secured with screws to a stamped steel air-
bag mounting bracket that is secured with screws to
the tubular steel instrument panel structural support
above the glove box opening. The end plates are
secured to each side of the passenger airbag housing
with screws.
The passenger airbag unit used in this model is a
Next Generation-type that complies with revised fed-
eral airbag standards to deploy with less force than
those used in some prior models. The airbag housing
contains the folded airbag cushion, the airbag
retainer, and the airbag inflator. The airbag is a rect-
angular fabric cushion. The airbag inflator is a solid
fuel, pyrotechnic-type unit that is secured to and
sealed within the airbag housing along with the
folded airbag cushion. The inflator initiator connector
receptacle is connected to the vehicle electrical sys-
tem through a dedicated take out of the vehicle wire
harness with a yellow connector insulator.
The passenger airbag and airbag door unit cannot
be repaired, and must be replaced if deployed, faulty
or in any way damaged.
OPERATION
The passenger airbag is deployed by an electrical
signal generated by the Airbag Control Module
(ACM) through the passenger airbag squib circuits to
the initiator in the airbag inflator. When the ACM
sends the proper electrical signal to the initiator the
electrical energy generates enough heat to initiate a
small pyrotechnic charge which, in turn, ignites
chemical pellets within the inflator. Once ignited,
these chemical pellets burn rapidly and produce a
large quantity of inert gas. The inflator is sealed to
the back of the airbag housing and a diffuser in the

TURBOCHARGER SYSTEM
DESCRIPTION
CAUTION: The turbocharger is a performance part
and must not be tampered with. The boost pressure
bracket is an integral part of the turbocharger. Tam-
pering with the boost pressure components can
reduce durability by increasing cylinder pressure
and thermal loading due to incorrect inlet and
exhaust manifold pressure. Poor fuel economy and
failure to meet regulatory emissions laws may
result. Increasing the turbocharger boost WILL NOT
increase engine power.
The turbocharger used on this vehicle is of the
variable turbine type. These turbochargers use the
entire exhaust energy to boost efficiency of the turbo-
charger and the engine.
The advantages of a turbocharger with variable
turbine geometry are:
²Higher charge pressure already in the lower and
in upper engine speed ranges.
²Higher torque as a result of improved cylinder
charge.
