This group covers the various standard and optional power distribution components used on this model. The power
distribution system for this vehicle consists of the following components:

•

Front Control Module (FCM)

•

Integrated Power Module (IPM)

•

Power Distribution Center (PDC)

•

Junction Block (JB)

•

Power Outlets

The power distribution system also incorporates various types of circuit control and protection features, including:

•

Automatic resetting circuit breakers

•

Blade-type fuses

•

Bus bars

•

Cartridge fuses

•

Circuit splice blocks

•

Flashers

•

Fusible links

•

Standard and Micro-Relays

Following are general descriptions of the major components in the power distribution system. See the owner’s man-
ual in the vehicle glove box for more information on the features and use of all of the power distribution system
components. Refer to Wiring Diagrams for complete circuit diagrams.

OPERATION

The power distribution system for this vehicle is designed to provide safe, reliable, and centralized distribution points
for the electrical current required to operate all of the standard and optional factory-installed electrical and electronic
powertrain, chassis, safety, security, comfort and convenience systems. At the same time, the power distribution
system was designed to provide ready access to these electrical distribution points for the vehicle technician to use
when conducting diagnosis and repair of faulty circuits. The power distribution system can also prove useful for the
sourcing of additional electrical circuits that may be required to provide the electrical current needed to operate
accessories that the vehicle owner may choose to have installed in the aftermarket.

INTEGRATED POWER MODULE

DESCRIPTION

The Integrated Power Module (IPM) (2) is a combina-
tion of a printed circuit board based module that con-
tains fuses and relays and the Front Control Module
(FCM) (3). The FCM contains electronics that control
the IPM as well as other vehicle functions. The IPM
connects directly to the battery positive via a stud
located on top of the unit. The ground connection is
via electrical connectors. The IPM provides the pri-
mary means of voltage distribution and protection for
many vehicle systems.

The IPM (2) is located in the engine compartment,
next to the battery (5) and in front of the Power Dis-
tribution Center (PDC) (1). It is secured to a bracket
with three locating slots that snap onto the bracket
tabs holding it securely in place. The printed circuit
board portion of the IPM cannot be repaired and must
be replaced if inoperative or damaged, (Refer to 8 -
ELECTRICAL/POWER DISTRIBUTION/INTEGRATED
POWER MODULE - REMOVAL).

OPERATION

All of the current from the battery and the generator output enters the integrated power module via a stud on the top
of the module. Internal connections of all of the power distribution center circuits is accomplished by a combination
of bus bars and a printed circuit board.

REMOVAL

1. Disconnect and isolate the battery negative cable.

2. Remove the Integrated Power Module (IPM) cover

by pulling up on the cover tabs (7) and pivoting the
cover outward.
