the vehicle speed remains greater than about twenty-
four kilometers-per-hour (fifteen miles-per-hour).
•
Vacuum Fluorescent Display Synchroniza-
tion - The EMIC transmits electronic panel lamp
dimming level messages which allows all other elec-
tronic modules on the PCI data bus with Vacuum
Fluorescent Display (VFD) units to coordinate their
illumination intensity with that of the EMIC VFD
units.
•
Vehicle Theft Security System - The EMIC
monitors inputs from the door cylinder lock switch-
(es), the door ajar switches, the ignition switch, and
the Remote Keyless Entry (RKE) receiver module,
then provides electronic horn and lighting request
messages to the Front Control Module (FCM) located
on the Integrated Power Module (IPM) for the appro-
priate VTSS alarm output features.
•
Wiper/Washer System Control - The EMIC
provides electronic wiper and/or washer request mes-
sages to the Front Control Module (FCM) located on
the Integrated Power Module (IPM) for the appropri-
ate wiper and washer system features. (Refer to 8 -
ELECTRICAL/WIPERS/WASHERS
- DESCRIP-
TION).
The EMIC houses six analog gauges and has pro-
visions for up to twenty-three indicators (Fig. 3) or
(Fig. 4). The EMIC includes the following analog
gauges:
•
Coolant Temperature Gauge
•
Fuel Gauge
•
Oil Pressure Gauge
•
Speedometer
•
Tachometer
•
Voltage Gauge
Some of the EMIC indicators are automatically
configured when the EMIC is connected to the vehi-
cle electrical system for compatibility with certain
optional equipment or equipment required for regula-
tory 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 provisions for the following indicators (Fig.
3) or (Fig. 4):
•
Airbag Indicator (with Airbag System only)
•
Antilock Brake System (ABS) Indicator
(with ABS or Rear Wheel Anti-Lock [RWAL]
brakes only)
•
Brake Indicator
•
Cargo Lamp Indicator
•
Check Gauges Indicator
•
Cruise Indicator (with Speed Control only)
•
Door Ajar Indicator
•
Electronic Throttle Control (ETC) Indicator
(with 5.7L Gasoline Engine only)
•
Gear Selector Indicator (with Automatic
Transmission only)
•
High Beam Indicator
•
Lamp Out Indicator
•
Low Fuel Indicator
•
Malfunction Indicator Lamp (MIL)
•
Overdrive-Off Indicator (with Automatic
Transmission only)
•
Seatbelt Indicator
•
Security Indicator (with Sentry Key Immo-
bilizer & Vehicle Theft Security Systems only)
•
Service Four-Wheel Drive Indicator (with
Four-Wheel Drive only)
•
Transmission Overtemp Indicator (with
Automatic Transmission only)
•
Turn Signal (Right and Left) Indicators
•
Upshift Indicator (with Manual Transmis-
sion only)
•
Washer Fluid Indicator
•
Wait-To-Start Indicator (with Diesel Engine
only)
•
Water-In-Fuel Indicator (with Diesel Engine
only)
Each indicator in the EMIC, except those located
within one of the VFD units, is illuminated by a ded-
icated LED that is soldered 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. Cluster illumination
is accomplished by dimmable incandescent back
lighting, which illuminates the gauges for visibility
when the exterior lighting is turned on. Each of the
incandescent bulbs is secured by an integral bulb
holder to the electronic circuit board from the back of
the cluster housing.
Hard wired circuitry connects the EMIC to the
electrical system of the vehicle. These hard wired cir-
cuits are integral to several wire harnesses, which
are routed throughout the vehicle and retained by
many different methods. These circuits may be con-
nected to each other, to the vehicle electrical system
and to the EMIC through the use of a combination of
soldered splices, splice block connectors, and many
different types of wire harness terminal connectors
and insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
The EMIC modules for this model are serviced only
as complete units. The EMIC module cannot be
adjusted or repaired. If a gauge, an LED indicator, a
VFD unit, the electronic circuit board, the circuit
board hardware, the cluster overlay, or the EMIC
housing are damaged or faulty, the entire EMIC mod-
