Ram 4500 - 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.

CAUTION!
When installing the totally integrated power mod-
ule cover, it is important to ensure the cover is
properly positioned and fully latched. Failure to
do so may allow water to get into the totally
integrated power module and possibly result in a
electrical system failure.
(Continued)
440
MAINTAINING YOUR VEHICLE
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 storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
Disconnect the Ignition-Off Draw (IOD) fuse located in
the Integrated Power Module, located in the engine
compartment. The IOD cavity includes a snap-in re-
tainer that allows the fuse to be disconnected without
removing it from the fuse block.
As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:
When reinstalling the IOD fuse push firmly until fully
seated; the gauges in the instrument cluster will do a
full sweep when the ignition switch is turned to the
RUN position. This is a normal condition.
When the vehicle is shipped from the factory, the IOD
fuse is in the up or extracted position. If the radio,
interior lamps, keyless entry or other features do not
work with the key OFF, check the position of the fuse

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this vehi-
cle’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 con-
nection 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 accu-
racy 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 nor-
mal may require special precautions.
All installations should be checked for possible interference
between the communications equipment and the vehicle’s
electronic systems.

POWER OUTLETS
• There are three possible 12 Volt power outlets located in the vehicle. Lower left
and lower right of the instrument panel and inside the upper lid of the center
storage compartment. A key symbol on the outlet cover indicates that the key
must be in the ON or ACC positions for the outlet to provide power. The
battery symbol on the outlet cover indicates that the outlet is connected to the
battery, and can provide power at all times. All accessories connected to the
outlet(s) should be removed or turned off when the vehicle is not in use to
protect the battery against discharge.
NOTE:
• 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 outlet 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 warranty.
