surface of the hinged cover. As well as housing fuses
and relays, the IPM is an electrical control and inter-
face center in the engine compartment. It provides
and distributes information to the rest of the vehicle.
The IPM controls the following features:

CONTROLLED POWER FEEDS

• BTSI

• EATX module power

• Front airbag system

• Front and rear marker lamps

• Front and rear park lamps

• Front fog lamps

• Headlamp power (High/Low beam)

• License plate lamp

RELAY CONTROLS

• Accessory relay

• Door node relay

• EBL relay

• Front and rear blower relay

• Front wiper HI/LOW relay

• Front wiper ON relay

• Horn relay

• Run relay

• Fuel pump relay

REMOVAL

NOTE: When a replacement IPM is installed in the
vehicle, the IOD fuse must be rotated to the “cus-
tomer” position.

(1) Disconnect and isolate the battery negative

cable.

(2) Remove the hood cable retaining clip near the

Integrated Power Module (IPM).

(3) Using a flat bladed tool, depress the four lock-

ing tabs on the side of the IPM (Fig. 1).

(4) Lift the IPM from the bracket.
(5) Disconnect the electrical harness connectors

from the IPM.

(6) Disconnect the battery connection to the IPM

by removing the nut attaching the connection to the
bolt.

INSTALLATION

NOTE: When a replacement IPM is installed in the
vehicle, the IOD fuse must be rotated to the “cus-
tomer” position.

(1) Install battery connection and retaining nut.

Tighten nut to 28 N·m (250 in. lbs.)

(2) Connect the electrical harness connectors to

the Integrated Power Module (IPM).

(3) Position IPM into place, and lock into position.
(4) Install the hood cable retaining clip.
(5) Connect battery negative cable.

IOD FUSE

DESCRIPTION

All vehicles are equipped with an Ignition-Off

Draw (IOD) fuse that is mounted in an asymmetrical
holder within the Integrated Power Module (IPM).
Prior to delivery to the customer, this fuse is posi-
tioned (shipping mode) for the “always on” equipment
only when the ignition is in the ON position. This
avoids long term drain on the battery during ship-
ping and storage. The IOD fuse will be aligned with
the other fuses on the same row it is in when in the
shipping mode. Dealer personnel are to reverse the
IOD fuse to “customer mode” by rotating the asym-
metrical fuse holder (with the IOD fuse in it) 180
degrees in its position to switch these features to bat-
tery power just prior to new vehicle delivery. The
fuse will NOT be aligned to the other fuses in the
row it is in when it is in the customer mode. When a
replacement IPM is installed in the vehicle, the
IOD fuse must be rotated to the “customer”
position.

OPERATION

The term ignition-off draw identifies a normal con-

dition 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 cur-
rent when the ignition switch is in the Off position,
including the clock. The only reason the IOD fuse is
reversed in its holder is to reduce the normal IOD of
the vehicle electrical system during new vehicle
transportation and pre-delivery storage to reduce
battery depletion, while still allowing vehicle opera-
tion so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation com-
pany and dealer personnel.

POWER OUTLET

DESCRIPTION

This vehicle is equipped with four electrical power

outlets. Two are located in the instrument panel cen-
ter stack, one in the rear of the center console and
one in the left quarter trim panel behind the rear
seats.

One instrument panel and the center console outlet

are battery powered - on at all times. The other out-
lets receive power only when the ignition is ON. The
ignition powered instrument panel outlet will accept
a cigar lighter element.

The operator can choose to make the ignition pow-

ered left rear quarter panel outlet battery powered

by repositioning a fuse in the Integrated Power Mod-
ule (IPM).

All outlets include tethered caps with ISO “bat-

tery” or “key” icons indicating whether they are bat-
tery or ignition powered.

REMOVAL

(1) Disconnect and isolate the battery negative

cable.

(2) Look inside and note position of the retaining

bosses (Fig. 2).

(3) Using external snap ring pliers with 90 degree

tips. Insert pliers with tips against bosses and
squeeze forcing bosses out of base.
