Dodge Neon / Neon SRT-4. Manual - part 92
the OFF position, the cluster drives each gauge to its
lowest position. The individual gauges are not ser-
viceable and require complete replacement of the
cluster if one or more gauges are inoperable.
NOTE: If any of the gauge pointers are stuck on the
wrong side of the pointer stop, perform one of the
following:
•
Pull the M1 fuse in the fuseblock (refer to Wir-
ing Diagrams for fuse locations) and key on. The
gauge pointer will “sweep” the gauges and return
all pointers to the correct side of the stop. Key OFF,
reinsert the M1 fuse. The cluster will “sweep” the
gauges
one
additional
time.
The
cluster
will
“sweep” the gauges anytime there was a change in
the state of the M1 fuse.
•
Perform the instrument self-diagnostic check
(Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER -
STANDARD PROCEDURE). This will “sweep” all the
pointers to the correct side of the pointer stop.
One button is used to switch the display from trip
to total mileage. Holding the button when the display
is in the trip mode will reset the trip mileage. This
button is also used to put the cluster in self-diagnos-
tic mode. Refer to Electrical, Instrument Cluster,
Standard Procedures- Cluster Self-Diagnostics. Most
of the indicators will come on briefly for a bulb check
when the ignition is turned from OFF to ON. All of
the LED’s are replaceable.
The cluster calculates the appropriate odometer
mileage based on PCI bus information received from
the PCM. The VF display also displays the “Door”
and “Cruise” messages. If the instrument cluster
experiences a loss of communication with the PCI
bus, the cluster will display “no buS” in the display.
If the cluster determines that there is not 8.0 volts at
the battery input, then the cluster shall alternately
display “FUSE” and the odometer mileage.
• Front Fog Lamp (if so equipped) - Hard wire
input - Cluster will illuminate the indicator when the
front fog lamp input is at Vehicle System Voltage
(VSV).
• Rear Fog Lamp (if so equipped) - Hard wire
input - Cluster will illuminate the indicator when the
rear fog lamp input is at VSV.
• Brake - Hard wire OR PCI bus driven - Cluster
will illuminate the indicator if the park brake switch
is grounded OR after receiving the appropriate mes-
sage from the ABS/PCM modules.
• ABS (if so equipped) - PCI bus driven - Cluster
will illuminate the indicator after receiving the
appropriate message from the ABS module.
• Cruise (if so equipped) - PCI bus driven - Clus-
ter will illuminate the indicator after receiving the
appropriate message from the PCM.
• Door - Hard wire input - Cluster will illuminate
the indicator if either door input is grounded for
more than 250 milliseconds.
• Left Turn Signal - Hard wire input - Cluster
will illuminate the indicator if the left turn signal
input is at VSV.
• Right Turn Signal - Hard wire input - Cluster
will illuminate the indicator if the right turn signal
input is at VSV.
• High Beam - Hard wire input - Cluster will
illuminate the indicator whenever the high beam
switch input is at VSV.
• Malfunction Indicator Lamp (MIL) - PCI bus
driven - Cluster will illuminate the indicator after
receiving the appropriate message from the PCM.
• Low Oil Pressure - PCI bus driven - Cluster
will illuminate the indicator after receiving the
appropriate message from the PCM.
• Low Fuel Indicator - Cluster will illuminate
based upon fuel level calculated by the cluster (using
data received from the hard wire input from the fuel
level sensor).
• Seat Belt - Hard wire - Cluster will illuminate
whenever the seat belt input is grounded with the
ignition in RUN mode.
• Battery - PCI bus driven - Cluster will illumi-
nate after receiving the appropriate message from
the PCM.
• Airbag - PCI bus driven - Cluster will illumi-
nate after receiving the appropriate message from
the airbag control module.
• Security (if so equipped) - PCI bus driven -
Cluster will illuminate whenever the remote keyless
entry (RKE) input is grounded and the cluster has a
battery feed. Cluster will flash the indicator based
upon the message received from the sentry key
immobilizer module (SKIM).
The 7-position dimmer switch input is used by the
cluster to determine lighting intensity. the cluster
transmits dimming information to other modules via
the PCI bus.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - INSTRUMENT
CLUSTER LAMPS
Every time the vehicle is switched to the START/
RUN position, the cluster goes through a BULB
CHECK. This tests most of the indicator lamps and
Vacuum Fluorescent (VF) displays. If only one lamp
is out, remove the instrument cluster and replace the
defective bulb or Light Emitting Diode (LED). If
some or all of the lamps fail to light, refer to the
proper Body Diagnostics Procedures Manual.
