Ifneither of the following codes is an active code:
ACTIVE DTC SQUIB STATUS
Driver squib 1 open Status of Airbag is
Driver Squib 2 open Unknown.
3.1.2 CLOCKSPRING
The clockspring is mounted on the steering col-
umn behind the steering wheel. This assembly
consist of a plastic housing which contains a flat,
ribbon-like, electrically conductive tape that winds
and unwinds with the steering wheel rotation. The
clockspring is used to maintain a continuous elec-
trical circuit between the instrument panel wiring
and the driver airbag, the horn, and the vehicle
speed control switches if equipped. The clockspring
must be properly centered when it is reinstalled on
the steering column following any service proce-
dure, or it could be damaged. The clockspring can-
not be repaired and it must be replaced.
3.1.3 PASSENGER AIRBAG
The airbag door in the instrument panel top cover
the glove box is the most visible part of the passen-
ger side airbag system. The airbag door has a living
hinge at the top, which is secured to the instrument
panel top cover. Located under the airbag door is
the airbag cushion and its supporting components.
The airbag module includes a housing to which the
cushion and hybrid inflators are attached and
sealed. The 2001 Minivan is equipped with front
passenger airbag with dual stage inflators that
include a small canister of highly compressed argon
gas. The ORC uses vehicle crash severity, front
passenger seat belt switch status (buckled or un-
buckled) inputs to determine the level of airbag
deployment. When supplied with the proper electri-
cal signal, the hybrid inflator or inflators discharge
the compressed gas it contains directly into the
cushion. The airbag module cannot be repaired, and
must be replaced if deployed or in any way dam-
aged.
WARNING: THE PASSENGER AIRBAG
MODULE CONTAINS ARGON GAS
PRESSURIZED TO 17236.89 Kpa (2500 PSI).
DO NOT ATTEMPT TO DISMANTLE AN
AIRBAG MODULE OR TAMPER WITH ITS
INFLATOR. DO NOT PUNCTURE,
INCINERATE, OR BRING INTO CONTACT
WITH ELECTRICITY. DO NOT STORE AT
TEMPERATURE EXCEEDING 93ÉC (200ÉF).
REPLACE AIRBAG SYSTEM COMPONENTS
ONLY WITH PARTS SPECIFIED IN THE
MOPAR PARTS CATALOG. SUBSTITUTE
PARTS MAY APPEAR INTERCHANGEABLE,
BUT INTERNAL DIFFERENCES MAY RESULT
IN INFERIOR OCCUPANT PROTECTION. THE
FASTENERS, SCREWS, AND BOLTS
ORIGINALLY USED FOR THE AIRBAG
SYSTEM COMPONENTS HAVE SPECIAL
COATINGS AND ARE SPECIFICALLY
DESIGNED FOR THE AIRBAG SYSTEM. THEY
MUST NEVER BE REPLACED WITH ANY
SUBSTITUTES. ANY TIME A NEW FASTENER
IS NEEDED, REPLACE IT WITH THE
CORRECT FASTENERS PROVIDED IN THE
SERVICE PACKAGE OR SPECIFIED IN THE
MOPAR PARTS CATALOG.

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
