Chrysler 300M, Dodge Interpid. Manual — part 82
ANTI-LOCK BRAKE SYSTEM
INDICATOR
DESCRIPTION
The amber Anti-Lock Brake System (ABS) warning
indicator lamp is located on the instrument panel in
the instrument cluster.
OPERATION
When the ignition key is turned to the ON posi-
tion, the amber ABS warning indicator lamp is lit
until the Controller Anti-Lock Brakes (CAB) com-
pletes it’s self-tests and turns off the indicator lamp
(approximately 4 seconds). The amber ABS warning
indicator lamp will illuminate when the CAB detects
a condition that results in the shutdown of ABS func-
tion or when the instrument cluster does not receive
messages from the CAB. The CAB sends a message
across the PCI bus circuit that informs the instru-
ment cluster to turn on the amber ABS warning indi-
cator lamp.
NOTE: If the vehicle is equipped with traction con-
trol, the TRAC OFF indicator lamp will illuminate
anytime the amber ABS warning indicator lamp is
on.
Under most conditions, when the amber ABS warn-
ing indicator lamp is on, only the ABS function of the
brake system is affected; the base brake system and
the ability to stop the vehicle are not affected.

MASK/LENS
REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post.
(2) Remove the instrument panel left end cap.
(3) Remove steering column shroud cover.
(4) Tilt the steering column down into the lowest
position.
(5) Remove one screw (Limited/300M) to cluster
bezel
(6) Remove the items to expose bezel mounting
screws. Items vary depending on model.
(7) Remove two screws over upper cluster bezel in
instrument panel brow area and all remaining
attaching screws (four on Intrepid, Limited, and
300M, and five on Concorde).
(8) Using a trim stick (special tool #C-4755), gently
pry out on the instrument panel cluster bezel, discon-
nect headlamp switch connector, and remove.
(9) Remove the instrument cluster screws.
NOTE: Tilt steering wheel down to gain access for
instrument cluster removal.
(10) Remove the instrument cluster from panel.
The instrument panel wiring harness connectors are
self-aligning, mounted directly to the rear panel. A
force of approximately 9 kilograms (30 lbs.) will be
required to disengage the cluster from the connectors
and upper clips.
(11) Remove two screws to mask/lens (Fig. 3).
(12) Unsnap seven retaining tabs holding mask/
lens to cluster housing (Fig. 4).
(13) Separate mask/lens from instrument cluster
and remove.

INSTALLATION
(1) Align mask/lens with instrument cluster and
snap into place (Fig. 4).
(2) Snap seven retaining tabs holding mask/lens
into place.
(3) Install the two screws to mask/lens (Fig. 3).
NOTE: Tilt steering wheel down to gain access for
instrument cluster installation.
(4) Install the instrument cluster into instrument
panel. The instrument panel wiring harness connec-
tors are self-aligning, mounted directly to the rear
panel. A force of approximately 9 kilograms (30 lbs.)
will be required to engage the cluster to the connec-
tors and upper clips.
(5) Install the instrument cluster screws.
(6) Connect headlamp switch connector. Place the
cluster bezel into position and snap it into place
firmly.
(7) Install the two screws over upper cluster bezel
in instrument panel brow area and all remaining
attaching screws (four on Intrepid, Limited, and
300M, and five on Concorde).
(8) Install the items covering the bezel mounting
screws.
(9) Install the one screw (Limited/300M) to cluster
bezel
To service any instrument cluster component, the
instrument cluster must be removed from the instru-
ment panel. Use the following procedure:
(10) Tilt the steering column down into the highest
position.
(11) Install the steering column shroud cover.
(12) Install the instrument panel left end cap.
(13) Connect the negative battery cable remote ter-
minal to the remote battery post.
ODOMETER
REMOVAL
The instrument cluster must be removed for Odom-
eter service. Refer to Instrument Cluster Removal
and Installation.
On Intrepid, Concorde, and 300M models, the
odometer and PRNDL are one assembly retained by
three screws.
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post.
(2) Remove instrument cluster from vehicle. Refer
to Instrument Cluster Removal and Installation.
(3) Remove
five
cluster
back
cover
retaining
screws and remove the cover.
(4) Unplug connectors from printed circuit board.
(5) Remove cluster mask/lens from instrument
cluster. Refer to Mask/Lens Removal and Installa-
tion.
(6) Remove two screws to Vacuum Fluorescent
(VF) display Odometer and remove from cluster.
INSTALLATION
(1) Install the two screws to Vacuum Fluorescent
(VF) display.
(2) Install the cluster mask/lens on to the instru-
ment cluster. Refer to Mask/Lens Removal and
Installation.
(3) Install connectors to the printed circuit board.
(4) Install the five cluster back cover retaining
screws.
(5) Install the instrument cluster in vehicle. Refer
to Instrument Cluster Removal and Installation.
(6) Connect the negative battery cable remote ter-
minal to the remote battery post.
RED BRAKE WARNING
INDICATOR
DESCRIPTION
The red BRAKE warning indicator lamp is located
on the instrument panel in the instrument cluster.
OPERATION
The red BRAKE warning indicator lamp is sup-
plied 12-volt ignition feed anytime the ignition switch
is on. The indicator lamp is then illuminated by com-
pleting the ground circuit either through the parking
brake warning switch mounted on the parking brake
lever, the brake fluid level switch mounted in the
master cylinder reservoir, or the ignition switch when
in the CRANK position.
TACHOMETER
DESCRIPTION
Refer to Electrical, Instrument Cluster, Description
for more information.
OPERATION
The tachometer receives its information across the
PCI Bus from the Body Control Module (BCM). Infor-
mation on engine RPM is transmitted from the Pow-
ertrain Control Module (PCM) across the PCI Bus to
the BCM. The BCM calculates the position of the
tachometer pointer based on the input from the PCM
and adjusts the position of the gauge pointer to the
necessary position. This signal is sent over the PCI
Bus to the instrument cluster.

TRANSMISSION RANGE
INDICATOR (PRNDL)
DESCRIPTION
The shift position indicator is located in the instru-
ment cluster. It indicates the position of the manual
valve lever by illuminating an LED located under the
P, R, N, D, 3, or L (or Autostick) gear symbol.
OPERATION
The Transmission Range Sensor (TRS) sends a sig-
nal to the Powertrain Control Module (PCM) regard-
ing the position of the manual valve lever. The PCM
converts this signal into a Shift Lever Position (SLP)
and sends the information to the Body Control Mod-
ule (BCM) and the instrument cluster.
DIAGNOSIS AND TESTING - TRANSMISSION
RANGE INDICATOR
The transmission range sensor (on the valve body)
sends a signal to the PCM on the position of the
transaxle manual valve lever. The PCM receives the
switch signal and processes the data. The PCM sends
the Shift Lever Position (SLP) information to the
BCM via the communication bus. The BCM then out-
lines the appropriate transmission range indicator in
the instrument cluster.
If a problem arises with the transmission range
indicator, refer to TRANSMISSION RANGE INDI-
CATOR TEST , and the proper Body Diagnostic Pro-
cedures manual if the problem still exists.
To replace the transmission range indicator (Refer
