VEHICLE EMISSION CONTROL
INFORMATION (VECI)
DESCRIPTION
All vehicles are equipped with a combined vehicle
emission control information (VECI) label(s). The
label is located in the engine compartment on the
vehicle hood (Fig. 6). Two labels are used for vehicles
built for sale in the country of Canada.
The VECI label(s) contain the following:
²Engine family and displacement
²Evaporative family
²Emission control system schematic
²Certification application
²Spark plug and gap
The label also contains an engine vacuum sche-
matic. There are unique labels for vehicles built for
sale in the state of California and the country of
Canada. Canadian labels are written in both the
English and French languages. These labels are per-
manently attached and cannot be removed without
defacing information and destroying label.
VEHICLE IDENTIFICATION
NUMBER
DESCRIPTION
The Vehicle Identification Number (VIN) plate is
attached to the top left side of the instrument panel.The VIN contains 17 characters that provide data
concerning the vehicle. Refer to the decoding chart to
determine the identification of a vehicle.

of the preparation procedures performed just prior to
new vehicle delivery.
The PDC has a molded plastic cover that can be
removed to provide service access to all of the fuses
and relays in the PDC. An integral latch and hinges
are molded into the PDC cover for easy removal. A
fuse layout map is integral to the underside of the
PDC cover to ensure proper fuse and relay identifica-
tion. The IOD fuse is a 50 ampere maxi-type car-
tridge fuse and, when removed, it is stored in a spare
fuse cavity within the PDC.
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
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 operation so that the
vehicle can be loaded, unloaded and moved as needed
by both vehicle transportation company and dealer
personnel.
The IOD fuse is removed from PDC fuse cavity 15
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 toexceed 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.
REMOVAL
The Ignition-Off Draw (IOD) fuses normal installa-
tion location is cavity 15 in the power distribution
center. When the vehicle is shipped from the assem-
bly plant the fuse is removed to maintain proper bat-
tery voltage during vehicle storage (in some cases).
Dealer personnel must install the IOD fuse when the
vehicle is being prepared for customer delivery in
order to restore full electrical system operation.
(1) Turn the ignition switch to the Off position.
(2) Unlatch and open the cover of the power distri-
bution center.
(3) Remove the IOD fuse from fusecavity 15of
the power distribution center (Fig. 2).
(4) Store the removed IOD fuse by installing it in
the unused fuse storagecavity 11of the PDC (Fig.
2).
(5) Close and latch the power distribution center
cover.
INSTALLATION
(1) Be certain the ignition switch is in the Off posi-
tion.
(2) Unlatch and open the cover of the power distri-
bution center.
(3) Remove the stored IOD fuse from fuse storage
cavity 11of the power distribution center.
(4) Use a thumb to press the IOD fuse firmly down
into power distribution center fusecavity 15.
(5) Close and latch the power distribution center
cover.
