2005 JEEP LIBERTY wiring

WARNING!
•Relying on the airbags alone could lead to more
severe injuries in a collision. The airbags work
with your seat belt to restrain you properly. In
some collisions the airbags won’t deploy at all.
Always wear your seat belts even though you
have airbags.
•Being too close to the steering wheel or instru-
ment panel during airbag deployment could cause
serious injury. Airbags need room to inflate. Sit
back, comfortably extending your arms to reach
the steering wheel or instrument panel.
•If the vehicle has window bags, they also need
room to inflate. Do not lean against the door or
window. Sit upright in the center of the seat.
Airbag System Components
The airbag system consists of the following:
•Occupant Restraint Controller
•Remote Acceleration Sensors
•Airbag Warning Light
•Driver Airbag
•Passenger Airbag
•Window Bags above Side Windows (If Equipped)
•Steering Wheel and Column
•Instrument Panel
•Interconnecting Wiring
•Knee Impact Bolsters
•Front Acceleration Sensors

How The Airbag System Works
•
TheOccupant Restraint Controller (ORC)determines
if a frontal collision is severe enough to require the
airbags to inflate. Based on the level of collision
severity, the front control module determines the
proper rate of inflation. The front airbag inflators are
designed to provide different rates of airbag inflation
from direction provided by the ORC. The ORC maymodify the rate of inflation based on the occupant size
provided by the Occupant Classification Module. The
ORC will not detect roll over, or rear impacts.
The ORC monitors the readiness of the electronic parts
of the system whenever the ignition switch is in the
START or RUN positions. These include all of the
items listed above except the steering wheel and
column, and knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.
Also, the ORC turns on the AIRBAG warning light
(located in the instrument cluster) and PAD indicator
light (located in the front passenger grab handle) for 6 to
8 seconds for a self-check when the ignition is first turned
on. After the self-check, the AIRBAG warning light will
turn off. The PAD indicator light will function normally
(Refer to “Passenger Airbag Disable (PAD) Indicator
Light” in this section). If the ORC detects a malfunction

Maintaining Your Airbag System
WARNING!
•Modifications to any part of the airbag system could cause
it to fail when you need it. You could be injured if the
airbag system is not there to protect you. Do not modify the
components or wiring, including adding any kind of
badges or stickers to the steering wheel hub trim cover or
the upper right side of the instrument panel. Do not modify
the front bumper, vehicle body structure, or add aftermar-
ket side steps or running boards.
•Do not attempt to modify any part of your advanced airbag
system. The airbag may inflate accidentally or may not
function properly if modifications are made. Take your
vehicle to an authorized dealer for any advanced airbag
system service. If your seat including your trim cover and
cushion needs to be serviced in any way, take the vehicle to
your authorized dealer. Only manufacturer approved seat
accessories may be used. If it is necessary to modify an
advanced airbag system for persons with disabilities, con-
tact your authorized dealer.
WARNING!
•You need proper knee impact protection in a colli-
sion. Do not mount or locate any aftermarket equip-
ment on or behind the knee bolsters.
•It is dangerous to try to repair any part of the airbag
system yourself. Be sure to tell anyone who works on
your vehicle that it has an airbag system.
Airbag Warning Light
You will want to have the airbag system ready to inflate for
your protection in an impact. The airbag system is designed
to be maintenance free. If any of the following occurs, have
an authorized dealer service the system promptly:
•Does not come on during the 6 to 8 seconds after the
ignition switch is first turned on.
•Remains on after the 6 to 8 second interval.
•Comes on for any period of time while driving.

Engine Timing Belt — 2.4L Engine
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Ignition Wiring System — 2.4L Engine
Replace the ignition cables at the intervals described in
the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on “Maintenance Schedule A.” If,
however, you drive the vehicle frequently under dusty or
severe conditions, the filter element should be inspected
periodically and replaced if necessary at the intervals
shown on “Maintenance Schedule B.”
WARNING!
The air cleaner can provide protection in the case of
engine backfire. Do not remove the air cleaner
unless it is necessary for repair or maintenance.
Make sure that no one is near the engine compart-
ment before starting the vehicle with the air cleaner
removed. Failure to do so can result in serious
personal injury.
