DESCRIPTION AND OPERATION (Continued)
DOOR LOCK INHIBIT
When the Key-In switch is CLOSED (circuit G26
connected to circuit Z1) the Body Control Module
(BCM) ignores the operators request for power door
lock operation.
KEY-IN IGNITION WARNING
The Key-In chime is used to indicate to the opera-
tor that the key is in the ignition with the driver's
door OPEN. If the key is in the ignition, a ground
path is completed from the G26 circuit at the Body
Control Module (BCM), through the CLOSED switch,
to the Z1 circuit. The Z1 circuit is the ground circuit
and terminates at the body ground located at the left
kick panel.
When the driver's door is open the normally OPEN
door ajar switch CLOSES completing a path to
ground on circuit G75. The BCM processes this infor-
mation and turns on the chime.
FUNERAL MODE DISPLAY ILLUMINATION
The Body Control Module (BCM) controls the
intensity of the instrument cluster vacuum florescent
displays. This is accomplished using the input from
the headlamp dimmer switch on circuit E19. When
the exterior lamps are ON, and the dimmer switch is
moved to the high end of it's travel, the BCM sends a
message over the CCD Bus to the instrument cluster
for full lamp intensity.
8W - 45 BODY CONTROL MODULE
INSTRUMENT PANEL LAMP DIMMING
The Body Control Module (BCM) controls the
instrument panel lamp intensity using input from
the dimmer switch, circuit E19. The BCM uses the
CCD Bus to send a signal to the instrument cluster
for proper lamp intensity.
VEHICLE IMMOBILIZER MODULE
The vehicle immobilizer module is interfaces with
the Body Control Module (BCM). Circuits D1 and D2
are used to provide CCD communications between
the BCM and the module. Ground for the module is
supplied on circuit Z1.
Battery voltage for the module is supplied on cir-
cuit A15. This circuit is HOT at all times and pro-
tected by a 20 amp fuse located in the Power
Distribution Center (PDC). Circuit F18 is used to
provide a RUN/START input to the module.
Circuit G37 is connected between the module and
the Powertrain Control Module (PCM). Circuit P102
is used as a wake up signal from the BCM.

ual of the Diagnostic Test Procedures Manual.
