INSTRUMENT CLUSTER
DESCRIPTION
The instrumentation gauges are contained in a
subdial assembly within the instrument cluster. The
individual gauges are not serviceable. If one of the
cluster gauges becomes faulty, the entire cluster
would require replacement.
The mechanical instrument cluster with a tachom-
eter is equipped with a electronic vacuum fluorescent
transmission range indicator (PRND3L), odometer,
and trip odometer display.
The mechanical instrument cluster without a
tachometer is equipped with a cable operated trans-
mission range indicator (PRND21) and a vacuum flu-
orescent odometer display. It also has the following
indicators:
• Turn Signals
• High Beam
• Oil Pressure
• MIL
The instrument cluster is equipped with the follow-
ing warning lamps.
• Lift Gate Ajar
• Low Fuel Level
• Low Windshield Washer Fluid Level
• Cruise
• Battery Voltage
• Fasten Seat Belt
• Door Ajar
• Coolant Temperature
• Anti-Lock Brake
• Brake
• Airbag
• Traction Control
• Autostick
The mechanical instrument cluster without a
tachometer also has the following warning lamps:
• Turns Signals
• High Beam
• Oil Pressure
• Malfunction Indicator Lamp (MIL)
WATER IN FUEL LAMP - EXPORT
The Water In Fuel Lamp is located in the instru-
ment cluster. When moisture is found within the fuel
system, the sensor sends a message via the PCI data
bus to the instrument cluster. The sensor is located
underneath the vehicle, directly above the rear axle.
The sensor is housed within the fuel filter/water sep-
arator assembly cover. The sensor is not serviced sep-
arately. If found defective, the entire assembly cover
must be replaced.
OPERATION
Refer to the vehicle Owner’s Manual for operation
instructions and conditions for the Instrument Clus-
ter Gauges.
WATER IN FUEL LAMP - EXPORT
The Water In Fuel Sensor is a resistive type
switch. It is calibrated to sense the different resis-
tance between diesel fuel and water. When water
enters the fuel system, it is caught in the bottom of
the fuel filter/water separator assembly, where the
sensor is located. Water has less resistance than die-
sel fuel. The sensor then sends a PCI data bus mes-
sage to the instrument cluster to illuminate the
lamp.
If the lamp is inoperative, perform the self diag-
nostic test on the instrument cluster to check the
lamp operation before continuing diagnosis.
