IOD FUSE

DESCRIPTION

All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is disconnected within the Integrated Power Mod-
ule when the vehicle is shipped from the factory. Dealer personnel are to reconnect the IOD fuse in the Integrated
Power Module as part of the preparation procedures performed just prior to new vehicle delivery. The IOD fuse can
be removed to avoid discharging the battery by disconnecting non-essential, low-current memory functions that are
normally on at all times. A detent on the IOD fuse holder allows it to be stored in its normal cavity but out of contact.
The holder is pushed into place to restore power to the systems it supplies. The following circuits are protected by
the IOD fuse:

•

Cluster (CCN)

•

Diagnostic Connector

•

Map Lamps

•

Glove Box Lamp

•

Courtesy Lamps

•

Radio

•

Underhood Lamp

OPERATION

The term ignition-off draw identifies a normal condition where power is being drained from the battery with the igni-
tion 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. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle elec-
trical system during new vehicle transportation and pre-delivery storage to reduce battery depletion, while still allow-
ing vehicle operation so that the vehicle can be loaded, unloaded and moved as needed.

The IOD fuse is disconnected from Integrated Power Module when the vehicle is shipped from the assembly plant.
Dealer personnel must reconnect 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 another Fused B(+) circuit fuse.

The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery depletion when a vehi-
cle is to be stored for periods not to exceed about thirty days. However, it must be remembered that disconnecting
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 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.

REMOVAL

1. Disconnect and isolate the battery negative cable.

2. Pull the cigar lighter knob and element (1) out of

the cigar lighter receptacle base (6), or unsnap the
protective cap from the power outlet receptacle
base (6).

3. Look inside the cigar lighter or power outlet recep-

tacle base and note the position of the rectangular
retaining bosses (3) of the mount that secures the
receptacle base to the panel (4).

4. Insert a pair of external snap ring pliers (5) into the

cigar lighter or power outlet receptacle base and
engage the tips of the pliers with the retaining
bosses of the mount.

5. Squeeze the pliers to disengage the mount retain-

ing bosses from the receptacle base and, using a
gentle rocking motion, pull the pliers and the recep-
tacle base out of the mount.

6. Pull the receptacle base away from the instrument

panel far enough to access the instrument panel
wire harness connector (2).

7. Disconnect the instrument panel wire harness connector (2) from the cigar lighter or power outlet receptacle base

(6).

8. Remove the cigar lighter or power outlet mount from the instrument panel.

INSTALLATION

1. Connect the instrument panel wire harness connector to the cigar lighter or power outlet receptacle base con-

nector receptacle.

2. Install the cigar lighter or power outlet mount into the instrument panel.

3. Align the splines on the outside of the cigar lighter or power outlet receptacle base connector receptacle with the

grooves on the inside of the mount.

4. Press firmly on the cigar lighter or power outlet receptacle base until the retaining bosses of the mount are fully

engaged in their receptacles.

5. Install the cigar lighter knob and element into the cigar lighter receptacle base, or the protective cap into the

power outlet receptacle base.

6. Connect the battery negative cable.
