and a good ground. There should be no continuity. If
OK, go to Step 3. If not OK, repair the shorted panel
lamp dimmer signal circuit between the instrument
cluster and the left multi-function switch as required.
(3) Check for continuity between the panel lamp
dimmer signal circuit cavities of the instrument
panel wire harness connector (Connector C2) for the
instrument cluster and the cross body wire harness
connector for the left multi-function switch. There
should be continuity. If OK, use a DRBIII scan tool
to complete the diagnosis of the instrument cluster
illumination lighting. Refer to the appropriate diag-
nostic information. If not OK, repair the open panel
lamp dimmer signal circuit between the instrument
cluster and the left multi-function switch as required.

COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the cluster bezel from the instrument

(3) Remove the four screws that secure the instru-
ment cluster to the instrument panel structural sup-
port (Fig. 2).
(4) Pull the instrument cluster forward far enough
to access and disconnect the two instrument panel
wire harness connectors for the instrument cluster
from the connector receptacles on the back of the
cluster housing.

CLUSTER BULB

This procedure applies to each of the incandescent
cluster illumination lamp or indicator bulb and bulb
holder units. However, the illumination lamps and
the indicators use different bulb and bulb holder unit
sizes. They must never be interchanged.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the instrument cluster from the instru-
ment panel. (Refer to 8 - ELECTRICAL/INSTRU-
MENT CLUSTER - REMOVAL).
(3) Turn the bulb holder counterclockwise about
sixty degrees on the cluster electronic circuit board
(Fig. 3).
