Power Distribution Center: Description and Operation
Power Distribution Center
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 behind the battery. The PDC housing has a molded
plastic cover that includes two integral latches, one on each side. The PDC cover is easily removed for service access and has a convenient fuse
and relay layout map integral to the inside surface of the cover to ensure proper component identification.
The PDC housing is secured in the engine compartment at three points. Integral mounts on the front and inboard end of the PDC housing engage
and latch to stanchions that are integral to the molded plastic battery tray. An integral bracket on the rear of the PDC housing is secured with a
screw to the top of the left front inner wheel house. The PDC cover is unlatched and removed to access the battery/ generator cable input and
output connection studs. The PDC is integral to the headlamp and dash wire harness, which exits from the outboard end of the PDC housing.
All of the current from the battery/generator cable connections enters the PDC through a 140 ampere generator cartridge fuse that is secured with
screws just inside the inboard end of the PDC housing. The PDC houses up to ten maxi-type cartridge fuses, which replace all in-line fusible links.
The PDC also houses up to seven blade-type mini fuses, up to thirteen International Standards Organization (ISO) relays (one standard-type and
twelve micro-type), two joint connectors (one sixteen-way and one twenty-six-way) and a sixteen-way engine wire harness in-line connector.
Internal connection of all of the PDC circuits is accomplished by an intricate combination of hard wiring and bus bars.
The cartridge fuses, blade-type fuses and relays are available for service replacement. The PDC unit cannot be repaired and is only serviced as a
unit with the headlamp and dash wire harness. If the internal circuits or the PDC housing are faulty or damaged, the headlamp and dash wire
harness unit must be replaced.
