Power Distribution Module: Description and Operation

POWER DISTRIBUTION CENTER (PDC)
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 side of the engine compartment, below and to the outboard side of the master cylinder. 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.

All of the PDC outputs are through the integral engine compartment wire harness.

The PDC houses up to nine maxi-fuses. The PDC also houses up to ten mini-fuses, up to four full International Standards Organization (ISO) relays, and up to eight ISO micro-relays. Internal connection of all the PDC circuits is accomplished by an intricate network of hard wiring and bus bars. Refer to Power Distribution.

The fusible link, 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.
