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) when
the 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 IOD fuse is a 20 ampere blade-type mini fuse
and, when removed, it is stored in a fuse cavity adja-
cent to the washer fuse within the IPM.
OPERATION
The term ignition-off draw (IOD) identifies a nor-
mal condition 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 func-
tions for some of the electronic modules in the vehicle
as well as various other accessories that require bat-
tery 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 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.
The IOD fuse is removed from the Integrated
Power Module (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 trans-
parent 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 service or diagnosis of any
vehicle system or condition, other than the same pur-
pose 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 approximately thirty days. However, it mustbe 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 thirty days,
the battery negative cable should be disconnected to
eliminate normal IOD; and, the battery should be
tested and recharged at regular intervals during the
vehicle storage period to prevent the battery from
becoming discharged or damaged.
POWER OUTLET
DESCRIPTION
Two power outlets are installed in the instrument
panel center lower bezel. Two additional power out-
lets are incorporated into the left rear C-pillar and
the center console (if equipped). The power outlets
bases are secured by a snap fit. A hinged plug flips
closed to conceal and protect the power outlet base
when not in use.
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.

whenever the ignition switch is in the On position
and the A/C-heater control power is turned on.
The blower motor receives battery current when-
ever the front blower motor relay is energized. The
front blower motor relay output circuit is protected
by a fuse in the Integrated Power Module (IPM)
located in the engine compartment near the battery.
In the manual heater-A/C system, the blower motor
speed is controlled by regulating the path to ground
through the blower control switch and the blower
motor resistor. In the ATC system, the blower motor
speed is controlled by an electronic blower motor
power module, which uses a pulse width modulated
input from the ATC module and feedback from the
blower motor to regulate the blower motor ground
path it provides. The blower motor and wheel are
used to control the velocity of air moving through the
HVAC housing by spinning the blower wheel within
the housing at the selected speed or, in the ATC sys-
tem, at the selected or programmed speed.

For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring, diagrams, proper wire and con-
nector repair procedures, further details on wire
harness routing and retention, as well as pin-out and
location views for the various wire harness connec-
tors, splices and grounds.BLOWER MOTOR ELECTRICAL DIAGNOSIS
(1) Check the fuse (Fuse 10 - 40 ampere) in the
Integrated Power Module (IPM). If OK, go to Step 2.
If not OK, repair the shorted circuit or component as
required and replace the faulty fuse.
(2) Turn the ignition switch to the On position. Be
certain that the A/C-heater control power is turned
on. Check for battery voltage at the fuse (Fuse 10 -
40 ampere) in the IPM. If OK, go to Step 3. If not
OK, check the front blower motor relay.
(3) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the front HVAC wire harness connector
for the front blower motor resistor block (Manual
Temperature Control) or the front blower motor
power module (Automatic Temperature Control) from
the resistor or module connector receptacle. Recon-
nect the battery negative cable. Turn the ignition
switch to the On position. Be certain that the A/C-
heater control power is turned on. Check for battery
voltage at the fused front blower motor relay output
circuit cavity of the front HVAC wire harness connec-
tor for the front blower motor resistor block (MTC) or
the front blower motor power module (ATC). If OK,
go to Step 4. If not OK, repair the open fused front
blower motor relay output circuit to the IPM as
required.
(4) Turn the ignition switch to the Off position.
Disconnect and isolate the battery negative cable.
Disconnect the front blower motor pigtail wire con-
nector from the connector receptacle of the front
blower motor resistor block (MTC) or the front
blower motor power module (ATC). Use jumper wires
to connect a battery and ground feeds to the blower
motor pigtail wire connector. The blower motor
should operate. If OK with MTC, proceed to diagno-
sis of the front blower motor resistor block (Refer to
24 - HEATING & AIR CONDITIONING/CONTROLS
- FRONT/BLOWER MOTOR RESISTOR - DIAGNO-
SIS AND TESTING). If OK with ATC, use a DRBIII
scan tool to diagnose the front blower motor power
module. Refer to Body Diagnostic information. If not
OK with MTC or ATC, replace the faulty front blower
motor.
