eco JEEP LIBERTY 2002 KJ / 1.G Workshop Manual

The tailgate will lock and can not be unlocked if
the rear wiper switch is activated. The tailgate will
also lock if battery power is lost and then restored.
The tailgate/flip-up glass will not function with the
battery discharged or disconnected.
COMBINATION FLASHER
This flasher can be energized by the BCM to flash
all of the park/turn signal lamps as a optical alert for
the RKE panic function and, if the Flash Lights with
Lock programmable feature is enabled, as an optical
verification for the RKE lock event.
HORN RELAY
This relay can be energized by the BCM to sound
the horns as an audible alert for the RKE panic func-
tion and, if the Sound Horn on Lock programmable
feature is enabled, as an audible verification for the
RKE lock event.
LOW BEAM HEADLAMP RELAY
This relay can be energized by the BCM to flash
the headlamp low beams as an optical alert for the
RKE panic function.
OPERATION
POWER LOCKS
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 turns on the output drivers
and provides a voltage level to the door lock motor
for a specified time. All passenger doors can be
locked or unlocked using a mechanical button
mounted on the door trim panel. The front passenger
doors and tailgate can be locked or unlocked by using
the key cylinder (tailgate cylinder does not lock/un-
lock vehicle. It only unlocks the tailgate). The tail-
gate will lock and can not be unlocked if the rear
wiper switch is activated (this prevents the wiper
from operating when the tailgate is ajar). The tail-
gate will also lock if battery power is lost and then
restored.
AUTOMATIC DOOR LOCKS
When the automatic door locks are ENABLED the
door locks will lock when the vehicle is moving at
about 25.7 Km/h (15 mph), all doors are closed and
the accelerator pedal is depressed. This feature can
be switched ON or OFF as desired. When the system
is DISABLED the door locks will operate normally,
but will not lock automatically when the vehicle is
rolling. Once the automatic door locks have been
actuated, they will not try to lock the doors again
until a door is opened.
DOOR LOCK INHIBIT
If the key is in the ignition, in any position, and
either front door is ajar, the doors can not be locked,
but the unlock function still operates. Pressing the
RKE lock/unlock button under these conditions will
result in a normal lock/unlock activation.
After the key is removed from the Ignition Switch,
or the doors are closed, the power door locks will
operate normally.
DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock relays. If the door
lock switch is actuated continuously for more than
five seconds the BCM will turn the output driver
OFF (the BCM would consider the switch stuck).
Each lock motor is protected with a Positive Temper-
ature Coefficient device that prevents motor burn
out.
REMOTE KEYLESS ENTRY
²LOCK: Pressing the LOCK button locks all
doors, sounds horn (chirp) if enabled, and arms the
Vehicle Theft Security System, if enabled. The chirp
verifies that the RKE receiver has sent a message to
the BCM for door lock operation. If a door has not
been closed before pressing the LOCK button, the
vehicle may not be secured and the VTSS (if
equipped) will not arm until the door is closed.
²UNLOCK: Pressing the UNLOCK button once
will unlock the driver's door and activate the illumi-
nated entry system and disarm Vehicle Theft Secu-
rity System, if equipped. Pressing the UNLOCK
button twice within five seconds will unlock all doors.
²TAILGATE: Pressing the TAILGATE BUTTON
unlocks the tailgate remotely and opens the flip-up
glass.
²PANIC: Pressing the PANIC button sounds the
horns at half second intervals, flashes the exterior
lamps, and turns ON the interior lamps. The panic
alarm will remain on for three minutes, or until the
PANIC button is actuated again or the ignition
switch is turned to the RUN position.
The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code(s) in
its memory even after vehicle power has been inter-
rupted.
DIAGNOSIS AND TESTING - POWER LOCKS
The Body Control Module (BCM) enters a
reduced power mode after the key is turned
OFF. All diagnosis and testing of the power lock
system must be done with the key in the ON
position unless otherwise stated.
The most reliable, efficient, and accurate
means to diagnose the power lock system
requires the use of a DRBIIItscan tool and the

REMOTE KEYLESS ENTRY
MODULE
DESCRIPTION
When an RKE lock message is sent to the Body
Control Module (BCM), the BCM actuates the doors
and the tailgate lock, the interior lighting is turned
off, the horn chirps (if this feature is enabled), the
exterior lamps flash (if this feature is enabled) and, if
the vehicle is so equipped, the Vehicle Theft Security
System (VTSS) is armed. When an RKE unlock mes-
sage is sent to the BCM, the BCM actuates the
driver side front door (or all doors and the tailgate if
this feature is enabled) unlock, the interior lighting
is turned on and, if the vehicle is so equipped, the
VTSS is disarmed.When an RKE panic message is sent to the BCM,
the BCM actuates the driver side front door (or all
doors and the tailgate if this feature is enabled)
unlock, the interior lighting is turned on and, if the
vehicle is so equipped, the VTSS is disarmed. The
panic message will also cause the exterior lamps
(including the headlights) to flash, and the horn to
pulse for about three minutes, or until a second panic
message is sent to the BCM. A vehicle speed of about
25.7 kilometers-per-hour (15 miles-per-hour) will also
cancel the panic event.
Refer to the owner's manual for more information
on the features, use and operation of the RKE sys-
tem.
OPERATION
Whenever the vehicle battery power is interrupted,
the Remote Keyless Module (RKE) Module will retain
all vehicle access codes in its memory. When replac-
ing or adding a key fob transmitter (maximum of 4) a
DRB IIItscan tool is required to program the RKE
Module to accept the new Vehicle Access Code if a
customer owned transmitter is not available.

TAILGATE CYLINDER LOCK
SWITCH
DESCRIPTION
The tailgate cylinder lock switch is integral to the
key lock cylinder inside the tailgate. The tailgate cyl-
inder lock switch is a normally-open momentary
switch that is hard wired directly to the Body Con-
trol Module (BCM), and closes a path to ground
through an internal resistor when the lock cylinder is
rotated to the unlock or lock position.
The tailgate cylinder lock switch cannot be
adjusted or repaired.
OPERATION
The tailgate cylinder lock switch is actuated when
the key is inserted in the lock cylinder and turned to
the unlock or lock position. The tailgate cylinder lock
switch closes a path to ground through an internal
resistor for the Body Control Module (BCM) when
the tailgate key lock cylinder is in the lock or unlock
position, and opens the ground path when the lock
cylinder is in the neutral position. The BCM reads
the switch status, then sends the proper switch sta-
tus messages to other electronic modules over the
Programmable Communications Interface (PCI) data
bus network. The tailgate cylinder lock switch unlock
status message is used by the BCM as an input for
Vehicle Theft Security System (VTSS) operation and
to tell the BCM to lock or unlock the tailgate. There
is no mechanical linkage between the tailgate key
cylinder and the latches.
DIAGNOSIS AND TESTING - TAILGATE
CYLINDER LOCK SWITCH

to be employed (Fig. 1).
ACTIVE RESTRAINTS The active restraints for
this model include:
²Front Seat Belts- Both front seating positions
are equipped with three-point seat belt systems
employing a lower B-pillar mounted inertia latch-
type retractor, height-adjustable upper B-pillar
mounted turning loops, a traveling lower seat belt
anchor secured to the outboard side of the seat
frame, and a traveling end-release seat belt buckle
secured to the inboard side of the seat frame. Both
front seat belt buckles include an integral Hall-effect
seat belt switch that detects whether its respective
seat belt has been fastened.
²Rear Seat Belts- All three rear seating posi-
tions are equipped with three-point seat belt sys-
tems. The outboard seating position belts employ a
lower C-pillar mounted inertia latch-type retractor, a
fixed position upper C-pillar mounted turning loop,
and a fixed lower seat belt anchor secured to the
floor panel. The rear seat center seating position belt
has an inertia latch-type retractor that is integral to
the rear seat back panel, and a cable from the seat
back latch locks the center belt retractor spool unless
the seat back is fully latched. The rear seat center
seating position belt lower anchor is secured to the
floor panel. All three rear seat belts have fixed end-
release seat belt buckles secured to the floor panel, a
single buckle unit on the right side and a double

equipped with three, fixed-position, child seat tether
anchors. Two anchors are integral to the back of the
right rear seat back panel, and one is integral to the
left rear seat back panel.
PASSIVE RESTRAINTS The passive restraints
available for this model include the following:
²Dual Front Airbags- Multistage driver and
front passenger airbags are available for this model.
This airbag system is a passive, inflatable, Supple-
mental Restraint System (SRS) and vehicles with
this equipment can be readily identified by the ªSRS
- AIRBAGº logo molded into the driver airbag trim
cover in the center of the steering wheel and also
into the passenger airbag door on the instrument
panel above the glove box (Fig. 2). Vehicles with the
airbag system can also be identified by the airbag

cluster for about seven seconds as a bulb test eachtime the ignition switch is turned to the On position.
A pyrotechnic-type seat belt tensioner is integral to
the driver side front seat belt retractor mounted on
the lower B-pillar of all models equipped with dual
front airbags.
²Side Curtain Airbags- Optional side curtain
airbags are available for this model when it is also
equipped with dual front airbags. This airbag system
is a passive, inflatable, Supplemental Restraint Sys-
tem (SRS) and vehicles with this equipment can be
readily identified by a molded identification trim but-
ton with the ªSRS - AIRBAGº logo located on the
headliner above each B-pillar (Fig. 2).
The supplemental restraint system includes the
following major components, which are described in
further detail elsewhere in this service information:
²Airbag Control Module- The Airbag Control
Module (ACM) is also sometimes referred to as the
Occupant Restraint Controller (ORC). The ACM is
located on a mount on the floor panel transmission
tunnel, below the center of the instrument panel.
²Airbag Indicator- The airbag indicator is inte-
gral to the ElectroMechanical Instrument Cluster
(EMIC), which is located on the instrument panel in
front of the driver.
²Clockspring- The clockspring is located near
the top of the steering column, directly beneath the
steering wheel.
²Driver Airbag- The driver airbag is located in
the center of the steering wheel, beneath the driver
airbag trim cover.
²Driver Knee Blocker- The driver knee blocker
is a structural unit secured to the back side of and
integral to the instrument panel steering column
opening cover.
²Front Impact Sensor- Two front impact sen-
sors are used on vehicles equipped with dual front
airbags, one left side and one right side. One sensor

RESTRAINTS (Continued)

is located on the back side of each vertical member of
the radiator support.
²Passenger Airbag- The passenger airbag is
located on the instrument panel, beneath the passen-
ger airbag door on the instrument panel above the
glove box on the passenger side of the vehicle.
²Passenger Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door.
²Seat Belt Tensioner- The seat belt tensioner
is integral to the driver side front seat belt retractor
unit on vehicles equipped with dual front airbags.
²Side Impact Airbag Control Module-Two
Side Impact Airbag Control Modules (SIACM) are
used on vehicles with the optional side curtain air-
bags, one left side and one right side. One SIACM is
located behind the B-pillar trim near the base of each
B-pillar.
²Side Curtain Airbag- In vehicles equipped
with this option, a side curtain airbag is located on
each inside roof side rail above the headliner, and
extends from the A-pillar to just beyond the C-pillar.
The ACM, both SIACMs, and the EMIC each con-
tain a central processing unit and programming that
allow them to communicate with each other using
the Programmable Communication Interface (PCI)
data bus network. This method of communication is
used by the ACM for control of the airbag indicator
on all models equipped with dual front airbags.

Hard wired circuitry connects the supplemental
restraint system components to each other through
the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which
are routed throughout the vehicle and retained by
many different methods. These circuits may be con-
nected to each other, to the vehicle electrical system,
and to the supplemental restraint system compo-
nents through the use of a combination of soldered
splices, splice block connectors, and many different
types of wire harness terminal connectors and insu-
lators. Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further
details on wire harness routing and retention, as well
as pin-out and location views for the various wire
harness connectors, splices and grounds.
OPERATION
ACTIVE RESTRAINTS The primary passenger
restraints in this or any other vehicle are the stan-
dard equipment factory-installed seat belts. Seat
belts are referred to as an active restraint because
the vehicle occupants are required to physically fas-ten and properly adjust these restraints in order to
benefit from them. See the owner's manual in the
vehicle glove box for more information on the fea-
tures, use and operation of all of the factory-installed
active restraints.
PASSIVE RESTRAINTS The passive restraints
system is referred to as a supplemental restraint sys-
tem because they were designed and are intended to
enhance the protection for the vehicle occupants of
the vehicleonlywhen used in conjunction with the
seat belts. They are referred to as passive systems
because the vehicle occupants are not required to do
anything to make them operate; however, the vehicle
occupants must be wearing their seat belts in order
to obtain the maximum safety benefit from the facto-
ry-installed supplemental restraint systems.
The supplemental restraint system electrical cir-
cuits are continuously monitored and controlled by a
microprocessor and software contained within the
Airbag Control Module (ACM) and, on vehicles
equipped with the side curtain airbags, both Side
Impact Airbag Control Modules (SIACM). An airbag
indicator in the ElectroMechanical Instrument Clus-
ter (EMIC) illuminates for about seven seconds as a
bulb test each time the ignition switch is turned to
the On or Start positions. Following the bulb test,
the airbag indicator is turned on or off by the ACM
to indicate the status of the supplemental restraint
system. If the airbag indicator comes on at any time
other than during the bulb test, it indicates that
there is a problem in the supplemental restraint sys-
tem electrical circuits. Such a problem may cause air-
bags not to deploy when required, or to deploy when
not required.
Deployment of the supplemental restraints
depends upon the angle and severity of an impact.
Deployment is not based upon vehicle speed; rather,
deployment is based upon the rate of deceleration as
measured by the forces of gravity (G force) upon the
impact sensors. When an impact is severe enough,
the microprocessor in the ACM or the SIACM signals
the inflator unit of the airbag module to deploy the
airbag. The seat belt tensioner is provided with a
deployment signal by the ACM in conjunction with
the driver airbag. During a frontal vehicle impact,
the knee blockers work in concert with properly fas-
tened and adjusted seat belts to restrain both the
driver and the front seat passenger in the proper
position for an airbag deployment. The knee blockers
also absorb and distribute the crash energy from the
driver and the front seat passenger to the structure
of the instrument panel. The seat belt tensioner
removes the slack from the driver side front seat belt
to provide further assurance that the driver is prop-
erly positioned and restrained for an airbag deploy-
ment.
