Power Distribution Center (PDC): Description and Operation
Fig.6 Power Distribution Center Location
POWER DISTRIBUTION CENTER
All of the electrical current distributed throughout this vehicle is directed through the standard equipment Power Distribution Center (PDC). 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 compartment by one screw to
the rear of the PDC and two clips on the front side. A small molded plastic protective cover on the front right side of the engine compartment is
unsnapped to access the battery/generator cable input connection studs.
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 through a 140 ampere fusible link that is secured with screws 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 International Standards Organization (ISO) relays, and up to seven ISO micro-relays. Internal
connection of all the PDC circuits is accomplished by an intricate network of hard wiring and bus bars. Refer to the appropriate 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 connectors, 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.
