INTEGRATED POWER MODULE
DESCRIPTION
The Integrated Power Module (IPM) is a combina-
tion of the Power Distribution Center (PDC) and the
Front Control Module (FCM). The IPM is located in
the engine compartment, next to the battery on this
model (Fig. 1). The power distribution center mates
directly with the Front Control Module (FCM) to
form the IPM Fuse and Relay Center. The power dis-
tribution center (PDC) is a printed circuit board
based module that contains fuses and relays, while
the front control module contains the electronics con-
trolling the IPM and other functions. This IPM con-
nects directly to the battery positive via a four pin
connector. The ground connection is via two other
connectors. The IPM provides the primary means of
voltage distribution and protection for the entire
vehicle.
The molded plastic IPM housing includes a base
and cover. The IPM cover is easily opened or removed
for service access by squeezing the two marked cover
latches and has a fuse and relay layout map integral
to the inside surface of the cover. This IPM housing
base and cover are secured in place by an IPM
mounting bracket. This mounting bracket is designed
to allow the IPM to rotate counter-clockwise once the
locking tab is disengaged. The IPM mounting bracketis secured in place by bolts threaded into the left
front wheel house.
OPERATION
All of the current from the battery and the gener-
ator output enters the Integrated Power Module
(IPM) via a four- pin connector on the bottom of the
module. The IPM cover is unlatched and opened or
removed to access the fuses or relays. Internal con-
nections of all of the power distribution center cir-
cuits is accomplished by a combination of bus bars
and a printed circuit board. Refer to the Wiring sec-
tion of the service manual for complete IPM circuit
schematics.
REMOVAL
(1) Disconnect the negative and positive battery
cables.
(2) Remove the battery thermal guard from the
vehicle. Refer to the Battery section for the proce-
dure.
(3) Remove the battery from the vehicle. Refer to
the Battery section for the procedure.
(4) Using a flat-bladed screwdriver, twist the Inte-
grated Power Module (IPM) bracket retaining latch
outward to free the intelligent power module from its
mounting bracket (Fig. 2).
(5) Rotate the IPM counter-clockwise to access and
disconnect the various electrical connectors (Fig. 3).
(6) Free the IPM from its mounting bracket by
removing the IPM bracket clips from the hinge. A
screwdriver slipped up from under the hinge will free
the clips.

INSTALLATION
(1) Snap the left side of the Integrated Power Mod-
ule (IPM) housing in its mounting bracket and con-
nect the various electrical connectors. Care must be
taken that the Connector Positive Assurance (CPA)
on the five-pin B+ connector is positively engaged to
prevent generating a Diagnostic Trouble Code (DTC).
NOTE: IPM electrical connectors are color coded to
ease location reference.
(2) Being certain no wires are stressed or pinched,
rotate the IPM clock-wise until secured in mounting
bracket. An audible click may be heard.
(3) Install the battery in the vehicle. Refer to the
Battery section for the procedure.
(4) Install the battery thermal guard in the vehi-
cle. Refer to the Battery section for the procedure.
(5)
Connect the negative and positive battery cables.
(6) Using a diagnostic scan tool, check for any
stored diagnostic trouble codes and correct, check
that all vehicle options are operational before return-
ing the vehicle to service.
IOD FUSE
DESCRIPTION
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed from its normal
cavity in the Integrated Power Module (IPM) whenthe vehicle is shipped from the factory. Dealer per-
sonnel are to remove the IOD fuse from the storage
location and install it into the IPM fuse cavity
marked IOD as part of the preparation procedures
performed just prior to new vehicle delivery.
The IPM has a molded plastic cover that can be
removed to provide service access to all of the fuses
and relays in the IPM. An integral latch and hinges
are molded into the IPM cover for easy removal. A
fuse layout map is integral to the underside of the
IPM cover to ensure proper fuse and relay identifica-
tion. The IOD fuse is a 20 ampere blade-type mini
fuse and, when removed, it is stored in a fuse cavity
adjacent to the washer fuse within the IPM.
OPERATION
The term ignition-off draw identifies a normal condi-
tion where power is being drained from the battery with
the ignition switch in the Off position. The IOD fuse
feeds the memory and sleep mode functions for some of
the electronic modules in the vehicle as well as various
other accessories that require battery current when the
ignition switch is in the Off position, including the
clock. The only reason the IOD fuse is removed is to
reduce the normal IOD of the vehicle electrical system
during new vehicle transportation and pre-delivery stor-
age to reduce battery depletion, while still allowing
vehicle operation so that the vehicle can be loaded,
unloaded and moved as needed by both vehicle trans-
portation company and dealer personnel.
The IOD fuse is removed from the IPM fuse cavity
when the vehicle is shipped from the assembly plant.
Dealer personnel must install the IOD fuse when the
vehicle is being prepared for delivery in order to
restore full electrical system operation. Once the
vehicle is prepared for delivery, the IOD function of
this fuse becomes transparent and the fuse that has
been assigned the IOD designation becomes only
another Fused B(+) circuit fuse. The IOD fuse serves
no useful purpose to the dealer technician in the ser-
vice or diagnosis of any vehicle system or condition,
other than the same purpose as that of any other
standard circuit protection device.
The IOD fuse can be used by the vehicle owner as
a convenient means of reducing battery depletion
when a vehicle is to be stored for periods not to
exceed about thirty days. However, it must be
remembered that removing the IOD fuse will not
eliminate IOD, but only reduce this normal condition.
If a vehicle will be stored for more than about thirty
days, the battery negative cable should be discon-
nected to eliminate normal IOD; and, the battery
should be tested and recharged at regular intervals
during the vehicle storage period to prevent the bat-
tery from becoming discharged or damaged. Refer to
Battery Systemfor additional service information.

POWER OUTLET
DESCRIPTION
Accessory power outlets are standard equipment on
this model. Two power outlets are installed in the
instrument panel center lower bezel, which is located
near the bottom of the instrument panel center stack
area. Two additional power outlets are also incorpo-
rated into the vehicle, one on the left rear C-pillar
trim and the other in the center console, if equipped.
The power outlets bases are secured by a snap fit in
the appropriate bezels. A hinged plug flips closed to
conceal and protect the power outlet base when the
power outlet is not being used.
The power outlet receptacle unit and the power
outlet plugs are each available for service replace-
ment.
OPERATION
The power outlet base or receptacle shell is con-
nected to ground, and an insulated contact in the
bottom of the shell is connected to battery current.
The power outlet on the instrument panel marked
with a battery receives battery voltage from a fuse in
the Integrated Power Module (IPM) at all times. The
other power outlet on the instrument panel marked
with a key receives battery voltage only when the
key is in the on position.
The power outlet located in the center console
receives battery voltage all the time when positioned
between thefront seatsand key-on voltage when
positioned between therear seats. The power outlet
located on the C-pillar receives battery voltage only
when the key is in the on position.
