2002 JEEP LIBERTY turn signal bulb

system. Constant battery voltage is supplied to the
flasher so that it can perform the hazard warning func-
tion, and ignition switched battery voltage is supplied
for the turn signal function. The Integrated Circuit (IC)
within the combination flasher contains the logic that
controls the flasher operation and the flash rate. The
IC receives separate sense ground inputs from the
multi-function switch for the right and left turn sig-
nals, and from the hazard switch contacts or the BCM
for the hazard warning signals. A special design feature
of the combination flasher allows it to9sense9that a
turn signal circuit or bulb is not operating, and provide
the driver an indication of the condition by flashing the
remaining bulbs in the affected circuit at a higher rate
(120 flashes-per-minute or higher). Conventional flash-
ers either continue flashing at their typical rate (heavy-
duty type), or discontinue flashing the affected circuit
entirely (standard-duty type).
Because of the active electronic elements within
the combination flasher, it cannot be tested with con-
ventional automotive electrical test equipment. If the
combination flasher is believed to be faulty, test the
turn signal and hazard warning system. Then
replace the hazard switch with a known good unit to
confirm system operation.
DAYTIME RUNNING LAMP
RELAY
DESCRIPTION
The Daytime Running Lamp (DRL) relay (Fig. 8) is
a solid state relay that is used only on vehicles man-
ufactured for sale in Canada. The DRL relay featuresa die cast aluminum housing with integral cooling
fins that act as a heat sink for the solid state DRL
circuitry. Four male spade terminals extend from the
base of the relay through a potting material that
encloses and protects the DRL circuitry. Although the
DRL relay has four terminals that are laid out in a
footprint that is similar to that of a conventional
International Standards Organization (ISO) relay, a
standard ISO relay should never be installed in place
of the DRL relay. The DRL relay is installed in the
Junction Block (JB) on the driver side outboard end
of the instrument panel. Vehicles equipped with this
relay do not have a headlamp high beam relay
installed in the JB.
The DRL relay cannot be adjusted or repaired and,
if faulty or damaged, the unit must be replaced.
OPERATION
The Daytime Running Lamp (DRL) relay is a solid
state relay that controls the flow of battery current
to the high beam filaments of both headlamp bulbs
based upon a duty cycled control input received from
the Body Control Module (BCM) of vehicles equipped
with the DRL feature. By cycling the DRL relay out-
put, the BCM controls the illumination intensity of
the high beam filaments. The DRL relay terminals
are connected to the vehicle electrical system through
a connector receptacle in the Junction Block (JB).
The inputs and outputs of the DRL relay include:
²Battery Current Input- The DRL relay
receives battery current on a fused B(+) circuit from
a fuse in the Power Distribution Center (PDC).
²Ground Input- The DRL relay receives a path
to ground through a splice block located in the
instrument panel wire harness with an eyelet termi-
nal connector that is secured by a nut to a ground
stud on the driver side instrument panel end bracket
near the Junction Block (JB).
²Control Input- The DRL relay control input is
received from the BCM and/or the momentary optical
horn (flash-to-pass) output of the multi-function
switch through a high beam relay control circuit.
²Control Output- The DRL relay supplies bat-
tery current output to the headlamp high beam fila-
ments through the high beam relay output circuit.
Because of active electronic elements within the
DRL relay, it cannot be tested with conventional
automotive electrical test equipment. If the DRL
relay is believed to be faulty, replace the relay with a
known good unit to confirm system operation.

switch module housing is the hazard switch circuitry
and an electronic circuit board with the integral com-
bination flasher circuitry. The electronic combination
flasher circuitry performs both the hazard flasher
and turn signal flasher functions.
The hazard switch module cannot be adjusted or
repaired and, if faulty or damaged, the unit must be
replaced.
OPERATION
The hazard switch button is slightly recessed in
the instrument panel when the switch is in the Off
position, and latches at a position that is flush with
the outer surface of the instrument panel when in
the On position. The hazard switch module produces
an audible clicking sound that emulates the sound of
a conventional flasher whenever the turn signals or
the hazard warning system are activated. The hazard
switch module receives battery current on a fused
B(+) circuit from a fuse in the Junction Block (JB) at
all times for operation of the hazard warning, and on
a fused ignition switch output (run) circuit from
another fuse in the JB whenever the ignition switch
is in the On position for operation of the turn signals.
The module receives a path to ground through a
splice block located in the instrument panel wire har-
ness with an eyelet terminal connector that is
secured by a nut to a ground stud on the driver side
instrument panel end bracket near the JB. Inputs to
and outputs from the hazard switch module include:
²Panel Lamps Dimmer Input- A non-service-
able incandescent bulb soldered onto the hazard
switch module circuit board provides illumination of
the switch button when the exterior lighting is
turned On through an input received on the fusedpanel lamps dimmer switch signal circuit. However,
this bulb flashes on and off at full intensity whenever
the hazard switch button is in the On position,
regardless of the status of the exterior lighting.
²Hazard Switch Input- The combination
flasher circuitry of the hazard switch module receives
an internal ground input from the hazard switch to
request hazard flasher operation.
²Multi-Function Switch Input- The combina-
tion flasher circuitry of the hazard switch module
receives separate ground inputs from the turn signal
switch circuitry of the multi-function switch on right
and left turn switch sense circuits to request right or
left turn signal flasher operation.
²Body Control Module Input- The Body Con-
trol Module (BCM) can request hazard flasher opera-
tion by providing a ground path to the combination
flasher circuitry of the hazard switch module through
a hazard lamp control circuit.
²Turn Signal Output- The combination flasher
circuitry within the hazard switch module responds
to the flasher request inputs by energizing and
de-energizing two miniature relays on the module
circuit board. These relays control the switch output
through the right and left turn signal circuits. One
relay controls the right lamps, while the other con-
trols the left.
Because of active electronic elements within the
hazard switch module, it cannot be tested with con-
ventional automotive electrical test equipment. If the
hazard switch module is believed to be faulty, replace
the switch with a known good unit to confirm system
operation.

HAZARD SWITCH (Continued)

OPERATION
The controller board and logic circuitry of the
headlamp leveling motor will energize the motor and
extend or retract the motor pushrod through the
integral screw-drive transmission based upon the
voltage signal input received from the resistor multi-
plexed headlamp leveling switch. The ball formation
on the end of the headlamp leveling motor pushrod is
snapped into a socket formation on the back of the
movable reflector within the headlamp unit housing.
The headlamp leveling motors and switch have a
path to ground at all times. The headlamp leveling
components operate on battery current received
through the fused park lamp relay output circuit so
that the system will only operate when the exterior
lighting is turned On.
Because of active electronic elements within the
headlamp leveling motor, it cannot be tested with
conventional automotive electrical test equipment. If
the headlamp leveling motor is believed to be faulty,
replace the motor with a known good unit to confirm
system operation.

HEADLAMP LEVELING
SWITCH
DESCRIPTION
The headlamp leveling switch (Fig. 34) is used only
on vehicles manufactured for certain markets where
the headlamp leveling system is required. The head-
lamp leveling switch is mounted in the driver side
inboard trim bezel on the instrument panel, where it
is secured by molded latch features that are integral
to the switch housing. Only the switch bezel and
thumbwheel are visible on the outer surface of the
instrument panel trim bezel. The black plastic switch
thumbwheel is marked with white numbers ª0,º ª1,º
ª2,º and ª3,º each of which indicates one of the four
switch detent positions. Each higher number repre-sents a lower aiming position of the headlamp beam
relative to the road surface. The black, molded plas-
tic switch housing has an integral connector recepta-
cle on the back, a single latch feature on the top, and
two latch features (one on each side) on the bottom.
The switch is connected to the vehicle electrical sys-
tem through a dedicated take out and connector of
the instrument panel wire harness. Within the
switch housing is the leveling switch circuitry includ-
ing the switch contacts and a series resistor configu-
ration.
The headlamp leveling switch cannot be adjusted
or repaired and, if faulty or damaged, the unit must
be replaced.
OPERATION
The headlamp leveling switch receives battery cur-
rent on a fused park lamp relay output circuit from a
fuse in the Junction Block (JB) whenever the park
lamp relay is energized (park lamps are turned On).
The switch receives a path to ground through a splice
block located in the instrument panel wire harness
with an eyelet terminal connector that is secured by
a nut to a ground stud on the driver side instrument
panel end bracket near the JB. The only output from
the switch is a voltage signal that it provides to the
headlamp leveling motors on a headlamp adjust sig-
nal circuit. Each switch position selects a different
tap on a series resistor within the switch to provide a
different voltage signal to the leveling motors. The
higher the switch position number, the higher the
output voltage level.
The headlamp leveling switch can be tested using
conventional diagnostic tools and methods.

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.
(Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/COMMUNICATION - DESCRIP-
TION).
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.
