CLOCK
DESCRIPTION
The Analog Clock is located in the Instrument
Panel Switch Pod within the instrument cluster
bezel, just to the right of the instrument cluster (Fig.
1). It is of analog type and has one adjustment but-
ton that will forward the clocks hand position.
The clock is not serviced separately from the
instrument panel switch pod. If found defective, the
entire switch assembly must be replaced (Refer to 8 -
ELECTRICAL/INSTRUMENT
CLUSTER/INSTRU-
MENT PANEL SWITCH POD - REMOVAL).
OPERATION
To set the analog clock, at the top center of the
instrument panel, press and hold the button (Fig. 2)
until the setting is correct.

DIAGNOSIS AND TESTING - CLOCK
Refer to Wiring for the appropriate wiring informa-
tion and connector views. Check for 12v battery
power and ground at the instrument panel connector
end of the instrument panel switch pod. If both are
present, replace instrument panel switch pod (Refer
to 8 - ELECTRICAL/INSTRUMENT CLUSTER/IN-
STRUMENT PANEL SWITCH POD - REMOVAL). If
one or both are not present, repair short/open wire.

BODY CONTROL MODULE
DESCRIPTION
CAUTION: Do not swap BCM’s between vehicles or
with BCM’s off the shelf.
The Body Control Module (BCM) is located on the
bulkhead left side, underneath the instrument panel
(Fig. 1). The BCM utilizes integrated circuitry and
information carried on the Programmable Communi-
cations Interface (PCI) data bus network along with
many hard wired inputs to monitor many sensor and
switch inputs throughout the vehicle. In response to
those inputs, the internal circuitry and programming
of the BCM allow it to control and integrate many
electronic functions and features of the vehicle
through both hard wired outputs and the transmis-
sion of electronic message outputs to other electronic
modules in the vehicle over the PCI data bus.
OPERATION
The Body Control Module (BCM) is operational
when supplied with 12v battery power. The BCM
controls various vehicle functions. It also supplies
information to the instrument cluster to provide
visual and audible information to the vehicle occu-
pants. To provide and receive information, the mod-
ule
interfaces
with
the
vehicle’s
Programmable
Communication Interface (PCI) data bus network.
This network consists of the:
• Integrated Power Module (IPM) - which
incorporates the Power Distribution Center (PDC)
and the Front Control Module (FCM) into one assem-
bly.
• Next Generation Controller (NGC) - which
incorporates the Powertrain Control Module (PCM)
and the Transmission Control Module (TCM) into one
module.
• Instrument Cluster (IC)

(SKREEM) - which performs the functions of the

and Sentry Key Immobilizer Module (SKIM).
• Driver Door Module (DDM) and the Passen-
ger Door Module (PDM)
The BCM provides:
• A battery protection feature. - The BCM will
send a message to the IPM to turn off all exterior
lamps after 3 minutes and all interior lamps after 15
minutes after the ignition is turned off, if they are
not turned off by the driver.
• Compass/Minitrip support.
• Interior lighting (courtesy/reading lamps).
• Diagnostic reporting.
• Electronic liftgate release (with power door
locks).
• Exterior lighting.
• Headlamp time delay (with/without auto head-
lamps).
• Automatic headlamps (with electrochromatic
mirror).
• Illuminated entry.
• A fade to off feature. - This feature dims the
interior lighting (courtesy lamps) gradually if the
BCM does not receive any new input that would
cause the interior lamps to remain on.
• Pulse Width Modulated (PWM) instrument
panel dimming.
• Power liftgate switch input. - The BCM has 1
Liftgate switch input located in the overhead console.
• All stalk switch inputs including wipers and
light switches.
• Seat belt position input, indicating a buckled or
unbuckled seat belt.
• Turn signal operation.
• Fuel Level inputs.
• Monitors rear-door ajar switches, liftgate ajar
switches,
multi-function
switches,
multi-function
headlight switch, ignition switch, PCI Bus, and diag-
nostic tool. Based on input from these components,
the BCM will send requests over the PCI Bus to have
the Instrument Cluster perform various chime oper-
ations.
The BCM has internal diagnostic capabilities that
assist in diagnosing the vehicle’s body system. When
an
9Open9 or a 9Short9 circuit exists, the DRBIIIt
scan tool can read the stored BCM Diagnostic Trou-
ble Codes (DTC’s). The DTC’s are very descriptive in
identifying the appropriate feature that has faulted.
Refer to the appropriate Body Diagnostic Proce-
dures manual for Diagnosis and Testing.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the lower instrument panel silencer.
(3) Remove the knee blocker airbag (Refer to 8 -
ELECTRICAL/RESTRAINTS/KNEE BLOCKER AIR-
BAG - REMOVAL).
(4) Unclip the 72-way bulkhead connector from the
Body Control Module (BCM) mounting assembly.
(5) Move bulkhead wiring aside.
(6) Disconnect the five wire connectors from the
BCM.
(7) Remove the four screws holding the BCM to
the bulkhead (Fig. 2).
(8) Remove the BCM from the mounting bracket.
