INSTRUMENT CLUSTER
DESCRIPTION
The mechanical instrument cluster is an electro-
mechanical module which receives most of its infor-
mation directly from the various control modules, via
the PCI data bus.
The cluster includes:
• Speedometer
• Tachometer
• Vacuum Fluorescent Display (VF) odometer/trip
odometer and transmission range indicator with
automatic transmission
• Fuel gauge
• Temperature gauge
The warning and information indicators include
the following:
• Check Engine
• Airbag
• Charging system
• Low oil pressure
• High temperature
• Low fuel
• Seat belt
• Cruise (optional)
• Brake/park brake
• Anti-lock brake system (optional)
• High beam
• Front and Rear Fog lamps (optional)
• Vehicle Theft Security System alarm LED indi-
cator (optional)
• Turn signals
• Traction Control (Optional)
VF display warnings:
• Door
• Deck
OPERATION
The gauges are the magnetic air-core type. Point-
ers should rest at or below the low graduation.

gear information upon receipt of vehicle configuration
from the PCM. At initial power-up, you might be able
to potentially see the ATX gear letters. Once the
MTX information is received, the gear letters will be
turned off.
DIAGNOSIS AND TESTING - INSTRUMENT
CLUSTER
functional check of the odometer display, transmis-
sion range display and warning indicators after the
ignition is switched to RUN/START. If the cluster is
not receiving any PCI bus messages, the cluster will
appear non functional and "no bus" will appear in
the odometer display.
