BODY CONTROL MODULE
DESCRIPTION
The Body Control Module (BCM) is located in the
passenger compartment, attached to the bulkhead
underneath the left side of the instrument panel. The BCM utilizes integrated circuitry and informa-
tion carried on the Programmable Communications
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) supplies vehicle
occupants with visual and audible information and
controls various vehicle functions. To provide and
receive information, the BCM is interfaced to the
vehicle's serial bus communications network, referred
to as the Programmable Communications Interface
(PCI) bus. This network consists of the;
² Powertrain Control Module (PCM)
² Transmission Control Module (TCM)
² Mechanical Instrument Cluster (MIC)
² Occupant Restraint Controller (ORC)
² Compass/Mini-Trip Computer (CMTC)
² Electronic Vehicle Information Center (EVIC)
² Controller Antilock Brake (CAB)
² HVAC Control Module
² Sliding Door Control Modules (driver and pas-
senger side doors) ² Power Liftgate Module (PLG) ²
Audio system equipped with RAZ, RBU, RBK,
and RBB radios. ² Sentry Key Remote Entry Module (SKREEM).
² Side Impact Airbag Control Module (SIACM)
² Memory Seat Module (MSM)
² Sentry Key Immobilizer Module (SKIM)
The BCM is operational when battery power is
supplied to the module. The BCM provides the following features:
² Power Door Locks
² Automatic Door Locks
² Battery Protection - The BCM will automatically
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. ² Chime Control
² Compass/Mini-Trip support.
² Interior Lighting (Courtesy/Reading Lamps)
² BCM Diagnostic Reporting
² Electronic Liftgate Release (with Power Door
Locks) ² Exterior Lighting
² Headlamp Time Delay (with/without Automatic
Headlamps) ² Illuminated Entry
² Fade to Off Interior Lamps - This feature dims
the interior lighting (courtesy lamps) gradually if the
BCM does not receive any new inputs that would
cause the interior lamps to remain on. ² Pulse Width Modulated Instrument Panel Dim-
ming ² Door Lock Inhibit - This feature disables the
door lock functions if the key is in the ignition and
either front door is ajar. Pressing the Remote Keyless
Entry (RKE) lock/unlock button under these condi-
tions result in normal lock/unlock activation. The BCM has the ability to LEARN additional fea-
tures in the vehicle, provided the appropriate switch
input and PCI data bus messages are received. Refer
to the LEARNED FEATURES table.

DESCRIPTION - CIRCUIT FUNCTIONS
All circuits in the diagrams use an alpha/numeric
code to identify the wire and it's function. To identify
which circuit code applies to a system, refer to the
Circuit Identification Code Chart. This chart shows
the main circuits only and does not show the second-
ary codes that may apply to some models.

DESCRIPTION - SECTION IDENTIFICATION AND
INFORMATION
The wiring diagrams are grouped into individual
sections. If a component is most likely found in a par-
ticular group, it will be shown complete (all wires,
connectors, and pins) within that group. For exam-
ple, the Auto Shutdown Relay is most likely to be
found in Group 30, so it is shown there complete. It
can, however, be shown partially in another group if
it contains some associated wiring.
Splice diagrams in Section 8W-70 show the entire
splice and provide references to other sections the
splices serves. Section 8W-70 only contains splice dia-
grams that are not shown in their entirety some-
where else in the wiring diagrams.
Section 8W-80 shows each connector and the cir-
cuits involved with that connector. The connectors
are identified using the name/number on the dia-
gram pages.

CAUTION: Do not bump or hammer on steering col-
umn or steering column shaft when removing steer-
ing wheel from steering column shaft.
CAUTION: When installing steering wheel puller
bolts in steering wheel, do not thread bolt into
steering wheel more than a half inch. If bolts are
threaded into the steering wheel more than a half
inch they will contact and damage the clockspring.
(7) While holding steering wheel firmly in the
straight-aheadposition, remove the steering wheel
from steering column shaft using a steering wheel
puller (Fig. 37).
(8) Remove the puller from the steering wheel.
(9) If the remote radio switches need removed
from the steering wheel, (Refer to 8 - ELECTRICAL/
AUDIO/REMOTE SWITCHES - REMOVAL).
INSTALLATION
(1) If the remote radio switches need to be
installed on the steering wheel, (Refer to 8 - ELEC-
TRICAL/AUDIO/REMOTE SWITCHES - INSTALLA-
TION).
CAUTION: Do not force steering wheel onto steer-
ing column shaft by driving it on. Pull steeringwheel down onto shaft using only the steering
wheel retaining nut.
(2) Feed and route wiring from clockspring
through upper access hole in steering wheel.
(3) Align master serrations in steering wheel with
omitted spline on steering column shaft (at 12 o'clock
position). Align pin on lower half of clockspring with
slot in rear of steering wheel (Fig. 36) and slide the
