POWER DISTRIBUTION

CENTER
DESCRIPTION
All of the electrical current distributed throughout
this vehicle is directed through the standard equip-
ment Power Distribution Center (PDC) (Fig. 5). The
molded plastic PDC housing is located in the left
front corner of the engine compartment, just in front
of the coolant reservoir bottle. The PDC housing has
a molded plastic cover. The PDC cover is easily
removed for service access and has a convenient fuse
and relay layout label affixed to the inside surface of
the cover to ensure proper component identification.
The PDC housing is secured in the engine compart-
ment by one screw to the rear of the PDC and two
clips on the front side. A small molded plastic protec-
tive cover on the front right side of the engine com-
partment is unsnapped to access the battery/
generator cable input connection studs.

OPERATION

All of the PDC outputs are through the integral
engine compartment wire harness, which exits from
the front of the PDC housing.
All of the current from the battery/generator cable
connection enters the PDC that is secured with nuts

just inside the left end of the PDC housing. The PDC
houses up to fourteen maxi-fuse cartridges, which
replace all in-line fusible links. The PDC also houses
up to six blade-type fuses, up to four full Interna-
tional Standards Organization (ISO) relays, and up
to seven ISO micro-relays. Internal connection of all
the PDC circuits is accomplished by an intricate net-
work of hard wiring and bus bars. Refer to the appro-
priate wiring information. The wiring information
includes wiring diagrams, proper wire and connector
repair procedures, details of wire harness routing
and retention, connector pin-out information and
location views for the various wire harness connec-
tors, splices and grounds.
The fusible link, fuse cartridges, fuses and relays
are available for service replacement. The PDC unit
cannot be repaired and is only serviced as a unit
with the engine compartment wire harness. If the
PDC is faulty or damaged, the engine compartment
wire harness assembly must be replaced.

REMOVAL

The Power Distribution Center (PDC) is serviced
as a unit with the engine compartment wire harness.
If any internal circuit of the PDC or the PDC hous-
ing is faulty or damaged, the entire PDC and engine
compartment wire harness unit must be replaced.
(1) Disconnect and isolate the battery negative
remote cable.
(2) Disconnect each of the engine compartment
wire harness connectors. (Refer to 8 - ELECTRICAL/
