Power Distribution Center: Description

The electrical current distributed throughout this vehicle is directed through the Power Distribution Center (PDC) (1) and Integrated Power Module (IPM) (2). The PDC is located in the left front corner of the engine compartment, between the IPM and the brake master cylinder. The PDC houses maxi-type cartridge fuses, which replace most in-line fusible links. Some fusible links still exist in the electrical harness depending on powertrain combination. The PDC also houses blade-type mini fuses, and International Standards Organization (ISO) relays.

The PDC housing is secured in the engine compartment at three points. Integral mounts on both sides of the PDC housing engage and latch to stanchions that are integral to the molded plastic support bracket. The PDC is integral to the headlamp and dash wire harness, which exits from the bottom of the PDC housing. The PDC housing has a molded plastic cover that includes two integral latches and pivot hooks that snap over a hinge pin on the side of the PDC housing. The PDC cover is easily opened or 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 cannot be repaired and is only serviced as a unit with the headlamp and dash wire harness. If the PDC main housing unit, fuse wedges or the bus bars are inoperative or damaged, the complete headlamp and dash wire harness unit must be replaced.
