troMechanical Instrument Cluster (EMIC) module
that is located in the instrument panel above the
steering column opening, directly in front of the
driver (Fig. 1). The remainder of the EMIC, including
the mounts and the electrical connections, are con-
cealed at the back of the cluster housing or behind
the cluster bezel. The molded plastic EMIC housing
has four integral mounting tabs, two on the lower
edge of the housing and two on the upper edge. The
EMIC is secured to the molded plastic instrument
panel cluster carrier with two screws, and to the
underside of the instrument panel top pad hood for-
mation with two screws. All electrical connections to
the EMIC are made at the back of the cluster hous-
ing through a single take out and connector of the
instrument panel wire harness.

The EMIC gauges and indicators are protected by

an integral clear plastic cluster lens, and are visible
through a dedicated hooded opening in the instru-

ment panel top pad. Just behind the cluster lens is
the cluster hood and mask. The cluster hood serves
as a visor and shields the face of the cluster from
ambient light and reflections to reduce glare. The
cluster mask and the dial faces of the gauges are
multi-layered units. The mask features two large
round openings near its center through which the
two major gauges are visible, and two smaller round
openings stacked at the outboard side of each of the
large openings through which the four minor gauges
are visible. The dark, visible surface of the mask and
the gauge dial faces are the outer layer or overlay,
which is translucent. The darkness of this outer layer
prevents the cluster from appearing too 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 illumi-
nated to be readily visible. The underlying layer of
the overlay is opaque and allows light from the var-
ious indicator lamps behind it to be visible through
the outer layer of the mask and gauge dial faces only
through predetermined cutouts. The graphics, incre-
ments, and numerals on the gauge faces are also
translucent and illuminated from behind, while the
orange gauge pointers are illuminated internally. On
the lower edge of the cluster lens just right of center,
a small molded plastic odometer/trip odometer switch
knob protrudes through a dedicated hole in the lens.

Two EMIC modules are offered on this model, one

for Laredo models featuring black gauge dial faces,
and one for Limited models with gauge dial faces
that feature a brushed aluminum appearance. This
module utilizes integrated circuitry and information
carried on the Programmable Communications Inter-
face (PCI) data bus network for control of all gauges
and many of the indicator lamps. (Refer to 8 - ELEC-

also uses several hard wired inputs in order to per-
form its many functions. The EMIC module incorpo-

for

displaying odometer and trip odometer information,
as well as the cruise-on indicator display function.
Some variations of this cluster exist due to optional
equipment and regulatory requirements. The EMIC
includes the following analog gauges:

• Coolant Temperature Gauge

• Fuel Gauge

• Oil Pressure Gauge

• Speedometer

• Tachometer

• Voltage Gauge
This EMIC also includes provisions for the follow-

ing indicator lamps:

• Airbag Indicator

• Antilock Brake System (ABS) Indicator
