2015 JEEP CHEROKEE wiring

•After any collision, the vehicle should be taken to an
authorized dealer immediately.
Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition switch is turned to the “OFF” posi-
tion.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition switch is
turned to the “OFF” position.
•Unlock the doors automatically.
System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition
OFF.
Air Bag Warning Light
The air bags must be ready to inflate for your protection
in a collision. The Occupant Restraint Control-
ler (ORC) monitors the internal circuits and
interconnecting wiring associated with air bag
system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the air bag
system is not on and the air bags will not inflate.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 87

Maintaining Your Air Bag System
WARNING!
•Modifications to any part of the air bag system
could cause it to fail when you need it. You could
be injured if the air bag 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 aftermarket side steps or running boards.
•It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag system.

WARNING!(Continued)
•Do not attempt to modify any part of your air bag
system. The air bag may inflate accidentally or may
not function properly if modifications are made.
Take your vehicle to an authorized dealer for any
air bag system service. If your seat, including your
trim cover and cushion, needs to be serviced in any
way (including removal or loosening/tightening of
seat attachment bolts), take the vehicle to your
authorized dealer. Only manufacturer approved
seat accessories may be used. If it is necessary to
modify the air bag system for persons with dis-
abilities, contact your authorized dealer.
90 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!(Continued)
•Towing any trailer will increase your stopping
distance. When towing you should allow for addi-
tional space between your vehicle and the vehicle
in front of you. Failure to do so could result in a
collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

CAUTION!
Do not touch the new bulb with your fingers. Oil
contamination will severely shorten bulb life. If the
bulb comes in contact with any oily surface, clean the
bulb with rubbing alcohol.
5. Reconnect the wiring harness to the new bulb and
reinstall by inserting the new bulb straight into the fog
lamp housing until it locks in place.
6. Lock the lower door in the wheel liner.
Bodyside Mounted Back-up Lamp
1. Open the liftgate.
2. Remove the screws that fasten the tail lamp housing to
the vehicle.
3. Grasp the tail lamp and pull firmly rearward to
disengage the lamp from the vehicle.
4. Disconnect the electrical connector.
5. Twist the socket counterclockwise and remove from
housing.
6. Pull the bulb to remove it from the socket.
7. Replace the bulb and install the socket.

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into
this vehicle’s electronic system to provide immunity
to radio frequency signals. Mobile two-way radios
and telephone equipment must be installed prop-
erly by trained personnel. The following must be
observed during installation.
The positive power connection should be made
directly to the battery and fused as close to the
battery as possible. The negative power connection
should be made to body sheet metal adjacent to the
negative battery connection. This connection
should not be fused.
Antennas for two-way radios should be mounted on
the roof or the rear area of the vehicle. Care should
be used in mounting antennas with magnet bases.
Magnets may affect the accuracy or operation of
the compass on vehicles so equipped.
The antenna cable should be as short as practical
and routed away from the vehicle wiring when pos-
sible. Use only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio
to ensure a low Standing Wave Ratio (SWR).
Mobile radio equipment with output power greater
than normal may require special precautions.
All installations should be checked for possible in-
terference between the communications equip-
ment and the vehicle’s electronic systems.
