2001 CHRYSLER VOYAGER low oil pressure

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.
²PWM Instrument Panel Dimming
²Door Lock Inhibit
This feature disables the door lock functions if the
key is in the ignition and either front door is ajar.
Pressing the RKE lock/unlock button under these
conditions, result in normal lock/unlock activation.
²Power Sliding Door Switch Inputs
The BCM has 4 switch inputs for the power
sliding door feature: Located in the overhead con-
sole are the Left and Right side sliding door
switches to activate either or both sliding doors
under the proper conditions. Also are B-Pillar
switches located on the Left and Right B-pillar
posts.
²Power Liftgate Switch Input
The BCM has 1 Liftgate switch input located in
the overhead console
²Power Lockout Switch Input
The BCM has 1 Lockout switch that when en-
abled will disable the B-Pillar sliding door switches
from activating either sliding door when depressed.
When replacing a body control module there are 2
modules available, a Base and a Midline. The
Midline controller is used on vehicles that have
Power Door Locks. If a vehicle is equipped with the
Vehicle Theft Security System, the midline control-
ler becomes a premium when the theft feature is
enabled.
NOTE: DO NOT SWAP THE BODY CONTROL
MODULE BETWEEN VEHICLES OR BODY
CONTROL MODULES OFF THE SHELF.
Engineering does not recommend that service,
dealers or the plant swap Body Control Modules
(BCM) between vehicles or off the shelf. The BCM
has internal diagnostic capability that assists in
diagnosing the system. When an ªOpenº or a
ªShortº circuit exists, the diagnostic tool can be
used to read the BCM codes. The codes are very
descriptive in identifying the appropriate feature
that has faulted.
3.4 CHIME WARNING SYSTEM
The BCM monitors the door/liftgate ajar
switches, multifunction switches, headlight switch,
ignition switch, PCI bus, and the diagnostic tool to
perform various chime operations. The BCM uses a
low-side driver to control the chime located in the
cluster.
The chime system provides the Driver with warn-
ing chimes for:
²Seat belt
²Exterior lights on
²Key-in Ignition
²Key-in Accessory
²Engine temperature critical
²Low washer fluid
²Turn signals on
²Dome light on
²Low oil pressure
²Any warning lamp announcement
²High-speed warning Gulf Coast Countries (GCC)
only
The output sound intensity of the chime is ap-
proximately 72 decibels.
3.4.1 CHIME PRIORITY
The following list indicates the priority of the
chime when more than one chime is active at the
same time:
²Seat belt warning
²High-speed warning Gulf Coast Countries (GCC)
only
²Turn signal on
²Chime request
²Warning lamp announcement
The cluster is responsible to set priority on all
warning lamp announcement chimes.
3.4.2 CHIME ON CONDITIONS
The following is a list of the chime warnings and
when they will sound.

GENERAL INFORMATION

On vehicles equipped with AutoStick, the display
includes an O/D OFF indicator that is illuminated
when the driver presses the Overdrive Off button
on the transaxle shifter.
3.11.1 INSTRUMENT CLUSTER SELF TEST
1. Depress and hold the Odometer Reset button.
2. Turn the ignition switch to the RUN/START
position.
3. Release the Odometer reset button.
The Instrument Cluster will illuminate all indi-
cators and step the gauges through several calibra-
tion points. Also, the odometer will display any
stored codes that may have set.
3.11.2 MESSAGE CENTER
The Message Center is located above the brow of
the Instrument Cluster. It houses the following
warning indicators: Check Engine/Service Engine
Soon, high beam, left and right turn signals, Secu-
rity Alarm Set, and low oil pressure. On base
models equipped with the three-speed transaxle,
these indicators appear in the face of the cluster.
The Security Alarm set indicator is a red circle.
Activation of Instrument Cluster indicators is
coordinated with indicators in the message center
and EVIC to avoid redundancy. A revised safety
standard now requires that the seat belt warning
lamp in the Instrument Cluster remain lit if the
driver seat belt is not buckled. A headlamp out ISO
indicator has been added to the Instrument Cluster
to alert the driver when a headlamp is not function-
ing.
3.12 INTERIOR LIGHTING
3.12.1 COURTESY LAMP CONTROL
The body controller has direct control over all of
the vehicle's courtesy lamps. The body computer
will illuminate the courtesy lamps under any of the
following conditions:
1. Any door ajar and courtesy lamp switch on the
headlamp switch is not in the dome off position.
2. The courtesy lamp switch on the headlamp
switch is in the dome on position.
3. A Remote Keyless Entry unlock message is re-
ceived.
4. Driver door unlocked with key (with VTSS only).
3.12.2 ILLUMINATED ENTRY
Illuminated entry will be initiated when the cus-
tomer enters the vehicle by unlocking the doors
with the key fob, or with the key if the vehicle is
equipped with vehicle theft alarm. Upon exiting thevehicle, if the lock button is pressed with a door
open, illuminated entry will cancel when the door
closes. If the doors are closed and the ignition
switch is turned on, the illuminated entry also
cancels. The illuminated entry feature will not
operate if the courtesy lamp switch is in the dome
off position.
3.12.3 INTERIOR LIGHTING BATTERY
SAVER
If any of the interior lamps are left on after the
ignition is turned off, the BCM will turn them off
after 8 minutes. To return to normal operation, the
courtesy lamps will operate after the dome lamp
switch or door ajar switch changes state. The glove
box and switched reading lamps require that the
ignition be turned to the on/acc position.
3.13 MEMORY SYSTEM
The memory system consists of power driver 's
seat, power mirrors and radio presets. The Memory
Seat/Mirror Module (MSMM) is located under the
driver 's seat. It receives input from the following:
driver 's manual 8-way seat switch, driver 's seat
position sensors, PCI bus circuits, and the power
mirror sensors. The module uses these inputs to
perform the following functions: position the driv-
er 's memory seat, both exterior mirrors (during
recalls), and send/receive the memory system infor-
mation over the PCI bus.
The Memory Set Switch is wired to the Body
Control Module (BCM). When a button (either #1 or
#2) is pressed on the set switch causes the to BCM
send a message to the MSMM which in turn sends
a motion status messages to the BCM. If the BCM
receives no motion from the MSMM it will send a
recall message to the MSMM and radio (once igni-
tion is in run or accessory). The MSMM will in turn
position the drivers seat, both mirrors along with
recalling the radio presets. If the drivers seat or
either exterior mirror is inoperative from its own
respective switches, use the service information
and schematic to diagnose the problem. This man-
ual addresses the memory problems only and it is
assumed there is not a basic component failure.
3.13.1 POWER SEAT
The memory power seat provides the driver with
2 position settings for the driver 's seat. Each power
seat motor is connected to the MSMM with two
motor drive circuits. Each circuit is switched be-
tween battery and ground. By being able to bi-
directionally drive the circuits, the MSMM controls
the movement of the motors based on input from
the power seat switch or from the position sensors
when performing a memory recall. Each motor
