1996 CHRYSLER VOYAGER key battery

ACM monitors the system to determine the system
readiness. The ACM contains on-board diagnostics
and will light the AIRBAG warning lamp in the mes-
sage center when a problem occurs.
The driver and passenger airbag system is a safety
device designed to reduce the risk of fatality or seri-
ous injury, caused by a frontal impact of the vehicle.
The impact sensor provides verification of the
direction and severity of the impact. One impact sen-
sor is used. It is located inside the Airbag Control
Module (ACM) which is mounted on a bracket, just
forward of the center console. The impact sensor is
an accelerometer that senses deceleration. The decel-
eration pulses are sent to a microprocessor which
contains a decision algorithm. When an impact is
severe enough to require airbag protection, the ACM
micro processor sends a signal that completes the
electrical circuit to the driver and passenger airbags.
The sensor is calibrated for the specific vehicle and
reacts to the severity and direction of the impact.
CLOCKSPRING
The clockspring is snapped into a plastic mounting
platform on the steering column behind the steering
wheel. The clockspring is used to maintain a contin-
uous electrical circuit between the wiring harness
and the driver's airbag module. This assembly con-
sists of a flat ribbon like electrically conductive tape
which winds and unwinds with the steering wheel
rotation.
DRIVER AND PASSENGER AIRBAG MODULES
The Driver Airbag Module is located in the center
of the steering wheel. The Passenger Airbag Module
is located in the instrument panel above the glove
box (Fig. 1). The Driver Airbag Module cover contains
the horn switch, inflator device, and a fabric bag. The
airbag cover/horn switch is serviced separately from
the inflator and bag components. Refer to Group 8G,
Horns for proper service procedure for horn switch.
The Passenger Airbag Module is serviced as an
assembly.

GENERAL INFORMATION
INTRODUCTION
The Body Control Module (BCM) locks or unlocks
the doors when an actuation input signal from a door
lock switch or Remote Keyless Entry Module (RKE)
is received. The BCM signals lock and unlock relays
in the Junction Block to actuate the door lock motors.
The front doors, sliding door(s) and liftgate are
equipped with actuator motors to lock or unlock the
latch mechanisms. The front door lock actuator motor
is not serviced separately from the door latch. The
BCM locks the doors and liftgate automatically when
the vehicle is driven beyond the speed of 25.7 Km/h
(16 mph). The automatic door lock feature can be dis-
abled if desired. All doors and liftgate can be locked
or unlocked using mechanical button or key cylinder
methods.
DESCRIPTION AND OPERATION
AUTOMATIC DOOR LOCK FEATURE
The vehicle comes with two options for power door
locks:
²Rolling automatic lock (ENABLE), doors auto-
matically lock at approximately at 25.7 Km/h (16
mph).
²No rolling automatic lock (DISABLE), doors do
not automatically lock when the vehicle is moving.
The BCM is equipped with a disable feature to
stop the speed sensitive automatic door locks from
functioning. The DISABLE feature can be switched
ON or OFF as desired. When the system is DIS-
ABLED the door locks will operate normally, but will
not lock automatically when the vehicle is rolling.
When the door locks are ENABLED the door locks
will automatically lock when the vehicle is moving at
about 25.7 Km/h (16 mph).
DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock relay's operation.
If the door lock switch is actuated continuously for
more than one second the BCM will interrupt the
relay circuit. The door lock system is protected by a
40 amp fuse located in the Power Distribution Center
(PDC). The LOCK and UNLOCK relays are located
in the Junction Block. The Power Distribution Center
is located along side of the battery. The lock motors
are protected with Positive Temperature Coefficient
(PTC) device that prevents motor burn out.
NSPOWER DOOR LOCKS 8P - 1

DOOR LOCK INHIBIT FEATURE
The BCM cancels out the door lock switch actua-
tion, when the key is in the Ignition Switch and a
door is open. After the key is removed from the Igni-
tion Switch, or the doors are closed, the power door
locks will operate normally.
SLIDING DOOR LOCK MEMORY FEATURE
The door locks on the sliding door(s) can be actu-
ated when the door(s) are closed. If the sliding
door(s) are open when the door locks are actuated,
the BCM will hold the lock command in memory
until the door(s) is closed. When the door is closed
and the door jamb terminals make contact, signaling
the BCM to lock the sliding door(s) automatically.
Actuating the door lock switch to the unlock position
before the sliding door(s) are closed will cancel the
lock request.
DIAGNOSIS AND TESTING
AUTOMATIC DOOR LOCK SYSTEM TEST
When using a scan tool (DRB) for testing the auto-
matic door lock system, refer to the Body Diagnostic
Procedures Manual. Refer to Group 8W, Wiring Dia-
grams for circuit information and component loca-
tions.
DOOR LOCK MOTOR
Verify battery condition before testing door lock
motor(s), refer to Group 8A, Battery for proper diag-
nosis procedures.
To determine which motor is faulty, check each
individual door for electrical lock and unlock or dis-
connect the motor connectors one at a time, while
operating the door lock switch. In the event that
none of the motors work, the problem may be caused
by a shorted motor, a relay or a bad switch. Discon-
necting the defective motor will allow the others to
work.
To test an individual door lock motor, disconnect
the electrical connector from the motor. To lock the
door, connect a 12 volt power source to the positive
pin of the lock motor and a ground wire to the other
pin (Fig. 1), (Fig. 2), (Fig. 3) and refer to Group 8W,
Wiring Diagrams for pin locations. To unlock the door
reverse the wire connections at the motor pin termi-
nals. If these results are NOT obtained, replace the
motor.
DOOR LOCK SWITCH TEST
(1) Remove door lock switch bezel assembly from
door. Refer to Group 23, Body for removal proce-
dures.
(2) Disconnect wire connector from back of door
lock switch.(3) Depress switch to LOCK position.
(4) Using an ohmmeter, test switch resistance
between Pins 2 and 3. Refer to Door Lock Switch
Test and (Fig. 4).
(5) Depress switch to UNLOCK position.
(6) Test resistance between Pins 2 and 3.
(7) If resistance values are not within the param-
eters shown replace the door lock switch.

GENERAL INFORMATION
INTRODUCTION
Vehicles equipped with the Vehicle Theft Security
System (VTSS) system, the doors, liftgate, hood and
ignition circuit are monitored by the Body Control
Module (BCM) when the system is armed. The VTSS
will prevent the engine from starting until the BCM
receives a disarm signal. If the VTSS is triggered,
the horn will pulse, headlamps/marker lamps will
flash, and the VTSS warning lamp will flash. If BCM
determines the threat to be false and the VTSS is not
triggered again, the system will shut down and
rearm itself after three minutes. The VTSS monitor-
ing portion of the system is split into two sections.
The engine compartment section and the passenger
compartment section. If a malfunction occurs in the
engine compartment section, the passenger compart-
ment section would still arm and function normally.
If an electrical malfunction occurs in either section of
the system a Diagnostic Trouble Code (DTC) would
be stored the BCM memory to aid system repair.
DTCs can be retrieved using scan tool (DRB)
attached to the diagnostic connector above the accel-
erator pedal.
ENABLING
To initialize the VTSS feature the operator must,
with the engine compartment hood open, cycle the
key in the liftgate key cylinder to the unlock position
giving the BCM a disarm signal. At this time the
visual alarm outputs the headlamps and marker
lamps will function. However the audio alarm output
the horn and engine disable portion of the VTSS will
not function until there has been twenty consecutiveengine run cycles. When this has occurred the total
VTSS will function.
If during alarm being set the BCM receives a
request from the RKE module to enter PANIC mode
the BCM will cancel the alarm, return VTSS armed
state and then perform the RKE PANIC feature.
DESCRIPTION AND OPERATION
ARMING PROCEDURE
METHOD-A
(1) With the key removed from the ignition lock
and any door open, actuate one of the following:
²Power door lock button to LOCK,
²Key fob LOCK button
²Door lock key cylinder to locked position.
(2) Close all opened doors.
(3) After the last door is closed, an arming time-
out period of sixteen seconds will start, then the
VTSS will become armed.
METHOD-B
Actuating the key fob transmitter LOCK button,
key locking the front doors or liftgate with the doors
closed and the ignition locked will begin the arming
time-out period. If method-A, 16 second time-out
sequence was in process when method-B was actu-
ated, the 16 second time-out will restart from the
time of the second actuation.
If the security lamp does not illuminate at all upon
final door closure, it indicates that the system is not
arming.
The current VTSS status armed or disarmed shall
be maintained in memory to prevent battery discon-
nects from disarming the system.
NSVEHICLE THEFT SECURITY SYSTEM 8Q - 1

TIME-OUT PERIOD
The VTSS requires 16 consecutive seconds to time-
out and arm the alarm. If a door is key unlocked, key
fob unlocked. or the ignition is switched ON, the
VTSS will cancel out. To reset the VTSS, perform
methods A or B.
TRIGGERING THE VTSS
After the VTSS is armed, following actions will
trigger the alarm:
²Opening any door.
²Opening the hood
²Turning the ignition to the ON or unlock posi-
tion.
²The ignition switch can be turned to the acces-
sory position without triggering alarm system.

cylinder.
The Smart Key transponder cannot be repaired
and, if faulty or damaged, it must be replaced.
SMART KEY IMMOBILIZER SYSTEM INDICATOR
LAMP
The Smart Key Immobilizer System (SKIS) indica-
tor lamp gives an indication when the SKIS is faulty
or when the vehicle has been immobilized due to the
use of an invalid ignition key. The lamp is controlled
by the instrument cluster circuitry based upon mes-
sages received from the Smart Key Immobilizer Mod-
ule (SKIM) on the Chrysler Collision Detection (CCD)
data bus.
The SKIM sends messages to the instrument clus-
ter to turn the lamp on for about three seconds when
the ignition switch is turned to the On position as a
bulb test. After completion of the bulb test, the SKIM
sends bus messages to keep the lamp off for a dura-
tion of about one second. Then the SKIM sends mes-
sages to the instrument cluster circuitry to turn the
lamp on or off based upon the results of the SKIS
self-tests. If the SKIS indicator lamp comes on and
stays on after the bulb test, it indicates that the
SKIM has detected a system malfunction and/or that
the SKIS has become inoperative. If the SKIM
detects an invalid key when the ignition switch is
turned to the On position, it sends messages to the
instrument cluster to flash the SKIS indicator lamp.
The SKIM can also send messages to the instru-
ment cluster to flash the lamp and to generate a sin-
gle audible chime tone. These functions serve as an
indication to the customer that the SKIS has been
placed in its ªCustomer Learnº programming mode.
See Smart Key Immobilizer System Transponder Pro-
gramming in this group for more information on the
ªCustomer Learnº programming mode.
The SKIS indicator lamp uses a replaceable incan-
descent bulb and bulb holder on the instrument clus-
ter electronic circuit board. Refer to Group 8E -
Instrument Panel Systems for diagnosis and service
of a faulty SKIS indicator lamp. If the SKIS indicator
lamp comes on and stays on after the bulb test func-
tion, diagnosis of the SKIS should be performed with
a DRB scan tool and the proper Diagnostic Proce-
dures manual.
