Jeep Wrangler - 2012 Fuse Box Diagram

NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. The air bags may
not be ready to inflate for your protection. Promptly
check the fuse block for blown fuses. Refer to the label
located on the inside of the fuse block cover for the
proper air bag fuses. See your authorized dealer if the
fuse is good.
Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle’s systems per-
formed. The EDR is designed to record data related to
vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this vehicle
is designed to record such data as:
How various systems in your vehicle were operating;
Whether or not the driver and passenger safety belts
were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better understanding of
the circumstances in which crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no per-
sonal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law en-
forcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a
crash investigation.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
The front power outlet is powered from the ignition
switch. Power is available when the ignition switch is in
the ON or ACC position.
When the optional cigar lighter heating element is used
in the power outlet, it heats when pushed in and pops out
automatically when ready for use.
To preserve the heat-
ing element, do not hold the lighter in the heating
position.
A second power outlet is located inside the center console
and is powered directly from the vehicle battery.
CAUTION!
Do not exceed the maximum power of 160 Watts
(13 Amps) at 12 Volts. If the 160 Watt (13 Amp)
power rating is exceeded the fuse protecting the
system will need to be replaced.
Power outlets are designed for accessory plugs
only. Do not insert any other object in the power
outlets as this will damage the outlet and blow the
fuse. Improper use of the power outlet can cause
damage not covered by your New Vehicle Limited
Warranty.

CAUTION!
Continuous driving with the Transmission Tempera-
ture “HOTOIL” Warning message illuminated will
eventually
cause
severe
transmission
damage
or
transmission failure.
WARNING!
If the Transmission Temperature “HOTOIL” Warn-
ing message is illuminated and you continue operat-
ing the vehicle, in some circumstances you could
cause the fluid to boil over, come in contact with hot
engine or exhaust components and cause a fire.
gASCAP
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer display
area. Tighten the fuel filler cap properly and press the
TRIP ODOMETER button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
noFUSE
If the vehicle diagnostic system determines that the
Ignition Off Draw (IOD) fuse is improperly installed, or
damaged, a “noFUSE” message will display in the odom-
eter display area. For further information on fuses and
fuse locations refer to “Fuses” in “Maintaining Your
Vehicle”.
CHAngE OIL Message
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer for approximately
12 seconds after a single chime has sounded to indicate
the next scheduled oil change interval. The engine oil
change
indicator
system
is

CAUTION!
When
installing
the
Integrated
Power
Module
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Integrated Power
Module, and possibly result in an electrical system
failure.
(Continued)
CAUTION! (Continued)
When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than
21 days, you may want to take steps to protect your
battery. You may:
Remove Cartridge fuse #J13 in the Power Distribution
Center (PDC) labeled Ignition-Off Draw (IOD) and
store it in a safe location within the PDC.
Or, disconnect the negative cable from the battery.

MAINTAINING YOUR VEHICLE
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 properly 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 possible. 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 interference
between the communications equipment and the vehicle’s
electronic systems.
