(6) Depress the release (Arrow A) and lift the lever
arm (Arrow B) to disconnect each of the two frame
wire harness connectors for the cluster from the con-
nector receptacles on the back of the cluster housing
(Fig. 6).
(7) Lift the instrument cluster upward far enough
to disengage the two molded plastic pivot loops inte-
gral to the base of the cluster hood from the two
pairs of molded plastic pivot hooks that are integral
to the top of the instrument panel base structure.
(8) Remove the instrument cluster from the instru-
ment panel.
INSTALLATION
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for
the system capacitor to discharge before perform-
ing further diagnosis or service. This is the only
sure way to disable the supplemental restraint sys-
tem. Failure to take the proper precautions could
result in accidental airbag deployment.
(1) Position the instrument cluster to the instru-
ment panel.
(2) Align the two molded plastic pivot loops inte-
gral to the base of the cluster hood between the twopairs of molded plastic pivot hooks that are integral
to the top of instrument panel base structure, then
push downward on the top of the cluster until the
loops snap into engagement with the hooks (Fig. 6).
(3) Roll the top of the instrument cluster rearward
to access, reconnect, and latch the two frame wire
harness connectors for the cluster to the connector
receptacles on the back of the cluster housing.
(4) Engage and latch the Remote Keyless Entry
(RKE)/immobilizer module to the back of the instru-
ment cluster rear cover (Fig. 5)
(5) Roll the top of the instrument cluster forward
to position the instrument cluster into the instru-
ment panel.
(6) Install and tighten the two screws that secure
the instrument cluster mounting ears to the instru-
ment panel base structure (Fig. 4). Tighten the
screws to 2 N´m (20 in. lbs.).
(7) Reinstall the cluster top cover onto the instru-
ment panel. (Refer to 23 - BODY/INSTRUMENT
PANEL/TOP COVER - CLUSTER - INSTALLA-
TION).
(8) Reinstall the cluster bezel onto the instrument
panel. (Refer to 23 - BODY/INSTRUMENT PANEL/
CLUSTER BEZEL - INSTALLATION).
(9) Reconnect the battery negative cable.
CAUTION: If an ineffective and unresponsive Instru-
ment Cluster (IC) has been replaced with a new
unit, the new IC must be initialized and configured
for certain optional equipment on the vehicle using
a cluster programming procedure. (Refer to 8 -
ELECTRICAL/INSTRUMENT CLUSTER - STANDARD
PROCEDURE - CLUSTER PROGRAMMING). Failure
to correctly perform this programming procedure
(also referred to as parameterization) prior to the IC
being electronically locked down will result in the
IC being incorrectly and irreversibly configured for
improper vehicle equipment options, which will
require the IC be replaced again with another new
and unused unit to resolve.
ABS INDICATOR
DESCRIPTION
An Anti-lock Brake System (ABS) indicator is stan-
dard equipment on all instrument clusters. The ABS
indicator is located near the lower edge of the instru-
ment cluster, to the right of the multi-function indi-
cator display. The ABS indicator consists of the
International Control and Display Symbol icon for
ªFailure of Anti-lock Braking Systemº imprinted
within a rectangular cutout in the opaque layer of
the instrument cluster overlay. The dark outer layer
of the overlay prevents the indicator from being
clearly visible when it is not illuminated. An amber

tensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for

tem. Failure to take the proper precautions could
result in accidental airbag deployment.
(1) Disconnect and isolate the battery negative
cable.
(2) Locate the brake lamp switch on the pedal
bracket underneath the instrument panel (Fig. 4).(3) Depress the locking tab on the brake lamp
switch body behind the pedal bracket and rotate the

(1) Pull the plunger of the brake lamp switch out-
ward from the switch body to its travel limit (Fig. 5).
(2) Reconnect the vehicle wire harness to the
brake lamp switch connector receptacle.
(3) Depress and hold the brake pedal in the
depressed position until the brake lamp switch
installation is completed (Fig. 4).
(4) Insert the brake lamp switch plunger through
the mounting hole from behind until the switch lock-
ing collar is fully seated against the pedal bracket.
(5) Rotate the brake lamp switch clockwise until
the locking tab on the switch body fully engages the
pedal bracket. Full locking tab engagement will be
accompanied by an audible click.
